Non-Healing Wounds in Dogs and Cats: When Healing Stalls

It’s day 18. The wound is clean, it’s moist, it’s covered. And it looks exactly the same as it did at day 10. No new granulation islands. No edge contraction. The exudate has shifted from serous to something slightly cloudier. The tissue around the margin is pale instead of the pink-red you’d expect in an actively healing wound.

This wound has stalled — and continuing the current protocol isn’t going to change that.

Chronic non-healing wounds are one of the most frustrating management problems in small animal practice. Not because they’re rare, but because standard wound care is genuinely appropriate for most wounds — and the moment when it stops being appropriate isn’t always obvious. Understanding what biologically derails the healing cascade, which patients are predictably at risk, and what a biologic intervention actually does differently is what separates a wound that closes in five weeks from one that doesn’t close in five months.

The Biology of the Stalled Wound: What Goes Wrong When Healing Stops

Normal wound healing follows a defined sequence: hemostasis, inflammation, proliferation, remodeling. Each phase has a beginning and an end. In a stalled wound, the sequence breaks down at the transition from inflammation to proliferation — and the wound gets stuck cycling through an inflammatory response that can’t resolve.

Three mechanisms drive most of what goes wrong.

Biofilm. Biofilm is present in approximately 60% of chronic wounds, compared to just 6% of acute wounds. That difference isn’t incidental — biofilm is both a consequence of chronicity and a driver of it. The extracellular polymeric substance (EPS) matrix that holds biofilm together creates three compounding barriers: a physical barrier that blocks keratinocyte and fibroblast migration; a metabolic barrier, generating hypoxic and acidic gradients that suppress cell energy production; and an immunological barrier that masks bacterial surface signals from host immune cells while bacterial toxins actively damage wound bed tissue. S. aureus α-toxin depletes ATP in keratinocytes. P. aeruginosa phospholipase causes direct necrosis. The biofilm doesn’t just prevent healing — it actively dismantles the wound bed.

MMP dysregulation. Matrix metalloproteinases are necessary for normal wound remodeling, but in chronic wounds, elevated MMP-9 creates a protease-dominant environment that degrades the extracellular matrix scaffolding before new tissue can form. Bacterial proteases compound this — S. aureus degrades immunoglobulins and complement proteins; certain anaerobes target type IV and V collagen directly. The wound bed loses its structural matrix faster than it can replace it.

Cell cycle arrest. Fibroblasts from chronic wounds exhibit growth arrest driven by elevated CDK inhibitors p21 and p27. These cells accumulate in the wound but can’t proliferate. Meanwhile, excess TGF-β — present in chronically inflamed wounds — imposes a secondary brake on keratinocytes via Smad2/3 phosphorylation, preventing the epithelial migration needed to close the wound surface. The cellular machinery is present but biochemically locked.

The result is a wound that looks stable but is doing nothing — consuming resources, resisting standard dressings, and waiting for a different signal.

Which Patients Get Stuck: Common Causes in Dogs and Cats

Certain wound types and patient profiles are predictably prone to chronicity. Recognizing them early changes the management calculus.

Post-surgical dehiscence. The most common scenario in general practice. A wound that should have closed primarily reopens — most often due to tension, infection, or patient interference — and then fails to granulate adequately over the following weeks. The surgical field has already been traumatized once; fibroblasts in the wound margins may be compromised, and secondary biofilm establishment is common. Revision surgery in a poorly vascularized, previously disrupted field carries its own risks. This is often where a biologic intervention has its clearest return.

Pressure ulcers in recumbent patients. Dogs with neurological or orthopedic conditions who are non-ambulatory develop pressure sores over bony prominences that are mechanically and metabolically difficult to heal. Sustained pressure impairs capillary perfusion, creating a hypoxic wound bed — precisely the environment that prevents normal cellular proliferation and is most permissive to biofilm. These wounds can persist for months to years under standard care.

Bite wounds and infected wounds in immunocompromised patients. FIV-positive cats, patients on chronic corticosteroids, and animals with concurrent systemic disease represent a high-risk group. A bite wound in a healthy cat is an acute problem with a predictable course. The same wound in an immunocompromised patient can fail to resolve for months, particularly when polymicrobial antibiotic-resistant biofilm establishes in the wound bed.

Patients with endocrine disease. Hyperadrenocorticism and diabetes mellitus are well-documented drivers of impaired wound healing in dogs. Elevated cortisol suppresses fibroblast function, impairs collagen synthesis, and blunts the immune response needed to clear early wound contamination. Any patient presenting with a chronically non-healing wound that doesn’t fit the wound’s timeline should be screened for underlying endocrinopathy — no biologic intervention fully compensates for uncontrolled Cushing’s disease.

The common thread across these patients is that their wound biology has been disrupted at a systemic or local level in a way that standard topical care cannot address.

How Amniotic Membrane Powder Restarts the Cascade — Step by Step

Standard wound care — appropriate moisture, debridement, infection control — creates the conditions for healing. What it doesn’t do is provide the biochemical signal the wound needs to move from inflammation to proliferation. That’s the gap a biologic like Healion fills.

Decellularized amniotic membrane powder delivers a preserved payload of growth factors that are absent or depleted in the chronic wound environment. Measured concentrations from amniotic membrane preparations include epidermal growth factor (EGF), fibroblast growth factor (FGF), hepatocyte growth factor (HGF), keratinocyte growth factor (KGF), nerve growth factor (NGF), and TGF-β — the same signals that coordinate normal wound healing but that chronic wounds can no longer generate at adequate levels.

Lyophilized amniotic membrane preparations show significantly higher bioactive factor concentrations than fresh tissue — up to 3.8x the collagen content, 5.2x the VEGF, and 6.8x the bFGF per milligram. That concentration matters clinically: a lyophilized powder applied to a chronic wound bed delivers a more concentrated signal than fresh membrane or simple moist dressings.

The mechanism at the cellular level is well-characterized. In chronic wounds, excess TGF-β locks keratinocytes in a growth-arrested state via Smad2/3 phosphorylation — the cells can’t migrate or proliferate. Amniotic membrane EGF activates MEK and attenuates Smad2/3 phosphorylation, releasing the TGF-β-imposed brake on keratinocyte proliferation. This isn’t blunt inflammation suppression — it’s modulation of a specific pathway that the chronic wound has dysregulated. Minimal TGF-β signaling is still necessary for proper migration; the AM restores balance rather than eliminating a signal.

Simultaneously, amniotic membrane shifts macrophage behavior from pro-inflammatory (M1) toward pro-remodeling (M2), elevating IL-10 (anti-inflammatory), supporting controlled TGF-β for appropriate matrix remodeling, and increasing MMP-1 and MMP-3 for organized ECM turnover. The net effect is a wound environment that can finally transition out of the inflammatory phase and begin building new tissue.

In a controlled study of lyophilized amniotic membrane in dogs with full-thickness wounds, closure rates at week 3 were 88.6% in the treatment group versus 55.7% in controls. By week 5, treatment wounds showed restored epidermis, remodeled dermis, and recovered hair follicles — structural markers of genuine tissue regeneration, not just wound closure. A separate AVMA study of an ECM wound dressing in Beagles showed significantly higher epithelialization percentages at days 7, 9, 12, and 18 compared to standard protocol, with better histologic repair scores.

Healion also retains antimicrobial activity from native amniotic tissue — β-defensins with documented activity against P. aeruginosa and S. aureus including MRSA strains. In a wound where biofilm is part of the problem, this is a clinically meaningful addition to the protocol.

Practical Decision Points: When Should a GP Vet Reach for a Biologic?

The clinical question isn’t whether amniotic membrane powder works — the evidence supports it. The question is when in the management timeline it becomes the right tool.

A reasonable framework: if a wound is not showing clear signs of progression by day 14 to 21 under appropriate standard care, treat that as a stall signal rather than normal variation. Specifically:

  • No granulation islands forming at 14 days
  • Wound edges not contracting
  • Exudate shifting from serous to cloudy or purulent despite appropriate antibiotic coverage
  • Tissue at the wound margin appearing pale or grey rather than pink-red
  • Culture showing resistant organisms or polymicrobial contamination

At that point, consider whether there’s a systemic reason the wound is stalling — run a culture if you haven’t, screen for endocrine disease if the patient profile suggests it, reassess nutrition and pain management. Then layer in the biologic.

Healion’s bellow dispenser allows direct, sterile application to the wound bed without secondary processing — the powder format suits open wounds with irregular geometry and doesn’t require the wound to be prepared beyond standard debridement. It fits into an existing wound care protocol without requiring additional equipment or technique change.

The conversation with the client is straightforward: standard dressings keep the wound clean and provide the right environment. The powder provides the biological signal the wound has lost — growth factors and structural cues that tell the cells what to do next. That framing holds up to client questions and positions the intervention accurately.

For patients at high risk of chronicity — post-surgical dehiscence in an oncology patient, pressure sores in a recumbent dog, bite wounds in an immunocompromised cat — there’s a reasonable argument for starting the biologic earlier rather than waiting for the stall to establish.

Scar Prevention in Dogs and Cats: What Happens in the First Three Weeks

A client returns for a two-week post-op recheck after a routine mass removal on their dog’s flank. The incision is clean, the dog is comfortable, and healing is progressing normally. Then the client asks the question you’ll hear again and again: “Is the scar going to look like this forever?”

The honest answer is more nuanced than most vets have time to explain in a recheck appointment. Scar formation is a biological process that begins in the first hours after wound closure and is largely determined within the first three weeks — long before the scar is visible enough for an owner to judge. By the time a client notices a raised, thickened, or discolored scar at week six, the biology that created it is already finished.

That window — the acute inflammatory phase — is where intervention matters. And it’s where amniotic membrane powder changes what’s clinically possible.

Why Wounds Scar: The Three-Week Window That Matters

Normal wound healing proceeds in three overlapping phases: inflammation, proliferation, and remodeling. Scar tissue is the product of what happens in the transition between inflammation and proliferation — specifically, how well the wound resolves its inflammatory state before fibroblasts begin depositing collagen.

The key driver is TGF-β (transforming growth factor beta). Released by platelets and inflammatory cells immediately after injury, TGF-β recruits fibroblasts to the wound and signals them to produce collagen. This is necessary for wound closure. The problem arises when TGF-β signaling persists too long or is too intense — fibroblasts overproduce collagen, depositing it in disorganized bundles rather than the aligned architecture of normal dermis. The result is scar tissue.

Critically, research has shown that TGF-β suppression works at the transcriptional level — amniotic membrane downregulates the gene expression of TGF-β2, TGF-β3, and all three TGF-β receptor types in fibroblasts. This isn’t a surface-level effect. It’s an upstream interruption of the signaling cascade that determines whether a wound heals cleanly or scars.

The window for this intervention is weeks one through three. After that, the collagen framework is laid and the remodeling phase determines final scar quality — a slower, less modifiable process. Scars typically appear most pronounced at three to eight weeks post-closure and reach final form at six to twelve months. What they look like at week six was determined biologically in week two.

Can You Actually Prevent Scarring in Post-Surgical Wounds?

The short answer is: not completely, but meaningfully — if the intervention targets the right mechanism at the right time.

Standard post-op care focuses on infection prevention, moisture management, and keeping the patient from disrupting the wound. These are essential. But none of them address the inflammatory signaling driving fibrosis. Suturing technique affects scar width and tension. Infection increases inflammatory load. But the underlying TGF-β cascade runs regardless of how clean the incision is or how well the edges are apposed.

Amniotic membrane works through a distinct pathway. It modulates the macrophage response — shifting the population away from the pro-inflammatory M1 phenotype that amplifies TGF-β signaling, toward the pro-resolving M2 phenotype that supports organized tissue remodeling. This shift matters because macrophage polarization in the first one to two weeks is one of the strongest predictors of scar outcome in healing wounds.

A 2025 study published in Scientific Reports evaluated lyophilized (powdered) amniotic membrane on full-thickness skin wounds in dogs and found efficacy comparable to fresh membrane — validating that the decellularization and powdering process preserves the biologically active components responsible for healing modulation. Studies on canine amniotic-derived products have consistently demonstrated benefits in both in vitro models and in vivo wound healing, with outcomes including accelerated epithelialization and reduced inflammatory burden.

The practical implication: applying amniotic membrane powder during the acute phase — at closure and at early rechecks — gives the wound biology a better trajectory before the collagen deposition phase begins.

Why Cosmetic Outcomes Matter More Than Vets Often Assume

Post-surgical scar appearance is not a vanity concern — it’s a measurable driver of client satisfaction and practice loyalty. A study published in Veterinary Evidence found that cosmetic outcome as judged by the owner accounted for 37% of the variability in overall satisfaction with surgical procedures in dogs. That number is significant: roughly one in three points of client satisfaction after surgery is determined by how the wound looks, not how quickly the patient recovered or how well the procedure went.

There is also documented discordance between how veterinarians and owners assess incision appearance. Vets evaluate healing on clinical criteria — no dehiscence, no infection, appropriate healing progression. Owners evaluate on cosmetic criteria — hair regrowth, scar size, color, texture. These are different standards, and vets who address only the clinical criteria miss the metric that determines whether a client returns.

This matters particularly for procedures in cosmetically visible locations: facial mass removals, limb surgeries, flank incisions on short-coated breeds, and any procedure where hair regrowth may be incomplete. For breeders, show animals, or clients who simply place high value on appearance, the post-surgical cosmetic outcome is often the lasting impression of the entire clinical experience.

Adding Scar Prevention to Your Post-Op Protocol with Healion

Healion delivers decellularized amniotic membrane in a powder format via a sterile bellow dispenser — a practical design for post-surgical wound application where liquid or sheet formats would require more handling or risk of contamination.

The protocol addition is straightforward:

  • At closure — apply Healion to the wound bed before subcuticular or skin closure in cases where scar risk is elevated (cosmetically sensitive location, large wound surface area, high-tension closure, or breed predisposition to scarring)
  • Early post-op rechecks (days 3–7) — apply to the incision line if any wound edge separation, inflammation, or slow re-epithelialization is noted
  • Acute lacerations and traumatic wounds — apply after debridement to contaminated wounds where scar formation is expected given the wound mechanism

Healion modulates inflammation, enhances healing, and reduces scar tissue formation — beginning at the cellular level in the first week before scar architecture is established. The bellow dispenser allows precise, hands-off application directly to the wound surface without the mixing or handling challenges of liquid biologics.

Setting Client Expectations After Application

When you add Healion to a post-surgical protocol, give clients a clear timeline: “The wound will still go through a visible healing phase over the next several weeks. What we’re doing now is giving the tissue the best biological environment to heal with less scar formation. You’ll be able to judge the final result at about six months.” That framing manages expectations while communicating that you took a proactive step most practices don’t offer.

Clinical Bottom Line

Scar formation is determined in the first three weeks of healing — not at the six-week recheck when clients first comment on appearance. The biology is settled before the scar is visible. Intervening during the acute inflammatory phase, when TGF-β signaling and macrophage polarization are still modifiable, is the only window for meaningful scar prevention.

Healion brings an evidence-supported mechanism to that window: amniotic membrane matrix that suppresses fibrotic signaling, modulates inflammation toward resolution, and supports organized tissue remodeling from the first application. For surgical practices where client satisfaction matters — and where cosmetic outcome accounts for more of that satisfaction than most vets realize — it’s a meaningful addition to the post-op toolkit.

Veterinary Amniotic Wound Powder: When Standard Wound Care Isn’t Enough

A 6-year-old mixed-breed dog presents three weeks post-degloving injury. The wound is clean. Granulation tissue started, then stalled. You’ve cycled through wet-to-dry bandages, silver dressings, and a course of systemic antibiotics. The tissue looks flat. No measurable progress. The owner is frustrated and asking what comes next.

This is the chronic wound scenario that sends many practitioners back to the textbook. And it’s exactly the situation decellularized amniotic membrane powder was developed to address.

Healion, Vetrix’s veterinary amniotic wound powder, delivers a concentrated source of bioactive matrix proteins, growth factors, and anti-inflammatory signaling molecules directly to the wound bed. Here’s what the science says — and when to add it to your wound care toolkit.

Why Chronic Wounds Stall — and Why Standard Care Can’t Fix It

Acute wounds heal in a predictable sequence: hemostasis, inflammation, proliferation, remodeling. Chronic wounds don’t follow that sequence. They cycle through inflammation without resolving, accumulate senescent fibroblasts, and fail to transition into the proliferative phase that drives closure.

Repeated bandage changes, antimicrobial dressings, and topical antibiotics address symptoms. They don’t reset the signaling environment. Wound fluid in chronic cases is biochemically different from acute wound fluid — it’s rich in matrix metalloproteinases (MMPs) that degrade growth factors before they can act, and depleted of the cytokines that recruit reparative cells.

Standard moist wound healing (MWH) remains the foundation of veterinary wound management. But for wounds stuck in chronic inflammation, moisture retention alone isn’t sufficient. Something needs to shift the cellular environment — not just cover it.

That’s where amniotic membrane biologics enter the picture. The mechanism isn’t a newer dressing or a better antiseptic. It’s a fundamentally different approach: restoring the biological signals the wound needs to move forward.

How Decellularized Amniotic Membrane Powder Works

Amniotic tissue is uniquely anti-inflammatory by origin. It forms at the maternal-fetal interface — an immunologically privileged environment where the body must suppress rejection while simultaneously supporting rapid new tissue formation. That immunomodulatory capacity is preserved when amniotic membrane is decellularized and processed into powder form.

Three mechanisms are well-documented in peer-reviewed literature:

Macrophage reprogramming. Amniotic membrane traps pro-inflammatory neutrophils and M1 macrophages and induces apoptosis. At the same time, it skews macrophage differentiation toward the M2 phenotype — the reparative subtype that drives angiogenesis, fibroblast recruitment, and re-epithelialization. In a chronic wound, this shift is often the step that’s missing entirely.

TGF-β suppression. TGF-β (transforming growth factor beta) is the primary driver of fibrosis. In chronic wounds, sustained TGF-β signaling doesn’t produce organized tissue — it produces scar. Amniotic membrane suppresses this pathway, protecting the wound from excessive scar tissue formation. This is the mechanism behind Healion’s documented ability to reduce scarring, an outcome clients often notice and appreciate — particularly in cosmetically sensitive areas like the face or limbs.

Growth factor delivery. Decellularized amniotic matrix retains a preserved scaffold of HGF (hepatocyte growth factor), EGF (epidermal growth factor), FGF (fibroblast growth factor), and PDGF (platelet-derived growth factor). These proteins drive keratinocyte migration, fibroblast proliferation, and vascular ingrowth — the cellular machinery of closure.

A 2025 systematic review published in Springer Nature confirmed that amniotic membrane transplantation reduces inflammatory cytokines and inflammatory cell density in chronic wound biopsies compared to controls. In a canine clinical study, wounds treated with amniotic-derived conditioned media showed a 98.47% reduction in wound surface area at 15 days — compared to 57.14% in the control group — with complete histological regeneration by six weeks. (Source: International Journal of Molecular Sciences, MDPI)

The powder format is clinically significant. Unlike liquid biologics or hydrogel formulations that require mixing or direct manual contact during application, Healion’s bellow dispenser delivers sterile powder directly to the wound bed without introducing handling contamination. In wounds with irregular geometry — undermined edges, exposed tissue pockets, uneven granulation — powder conforms to the wound surface in ways a sheet or hydrogel cannot.

Can You Use Healion on Contaminated or Infected Wounds?

This is the question most practitioners ask first. The short answer: prepare the wound bed before applying.

Healion is not an antimicrobial product. However, amniotic membrane does express antimicrobial peptides — research on canine amniotic tissue has identified β-defensins 1 and 103 and Elafin, which show documented activity against Pseudomonas aeruginosa and Staphylococcus aureus, including MRSA strains. This provides a degree of protection against secondary contamination once the wound is prepared, but it does not substitute for active infection management.

The recommended clinical protocol:

  • Debride to viable, well-vascularized tissue
  • Culture if infection is suspected or the wound has been chronic
  • Resolve active infection with appropriate systemic or topical antimicrobials
  • Apply Healion once the wound bed is clean — granulating or stalled pre-granulation

This sequence matters. Applying a biologic to an infected wound bed doesn’t accelerate healing — the inflammatory burden from active infection will overwhelm the signaling benefit. The goal is to introduce Healion into a wound that’s clean but biologically stuck.

Once applied, re-bandage with a non-adherent primary layer. Standard secondary and tertiary bandage layers apply. Recheck timing depends on wound type and patient compliance, but most chronic wound cases benefit from reassessment at 7–10 days to document progress before the next application decision.

When to Reach for Healion: Clinical Indications and Patient Selection

Healion is indicated where the healing cascade has stalled and conventional management is no longer producing results. Practical trigger points:

  • Chronic wounds >3–4 weeks without measurable closure progress
  • Degloving injuries with large surface area or irregular wound margins
  • Post-surgical dehiscence when primary or delayed closure isn’t viable
  • Pressure wounds and decubital ulcers in debilitated or recumbent patients
  • Traumatic wounds with exposed deep structures as an adjunct to reconstructive planning
  • Cosmetically sensitive locations where scar reduction is a priority — face, limbs, areas of expected hair regrowth

Healion is not a first-line treatment for acute wounds that are progressing on standard protocol. Those wounds heal well with conventional care. Healion is the intervention for cases where you’re three or four weeks in, the wound looks clean, and nothing is moving.

Patient selection is straightforward. Any dog or cat with a nonhealing wound and a prepared wound bed is a candidate. Decellularized amniotic membrane is immunologically inert by structure — the decellularization process removes cellular components that trigger immune response, leaving behind the extracellular matrix scaffold. No documented biocompatibility concerns exist for canine or feline patients.

What Clients Will Notice

For wounds that have plateaued for weeks, client communication is as important as clinical management. When healing accelerates after Healion application, clients see the change — and it shifts their confidence in the treatment plan.

Reduced scar tissue formation is often the outcome clients comment on most, especially in dogs with wounds on the face or legs where cosmetic outcome matters. Setting clear expectations — “we’re introducing a biologic that changes how the tissue signals at the cellular level, not just a different dressing” — helps clients understand why this step is different from everything that’s been tried so far.

Clinical Bottom Line

Chronic wounds are one of the most frustrating problems in small animal practice — not because the diagnosis is unclear, but because standard treatment reaches its ceiling and progress stops. The biology behind that stall is well-understood: the signaling environment is disrupted, and no dressing change will fix it.

Decellularized amniotic membrane powder addresses that directly. Healion modulates inflammation, suppresses fibrosis, and delivers the growth factor signals the wound needs to move forward — in a sterile, easy-to-apply format built for veterinary wound management.

For the cases on your treatment board that aren’t moving, it belongs in the conversation. Explore Healion’s clinical profile and request a sample for your practice at RethinkHealing.com.

How to Treat Bite Wounds in Dogs

Small dog on a vet’s tableBite wounds are one of the most common reasons dogs see their veterinarians. If a dog is bitten or gets into a fight with another dog, this is what needs to happen first:

  1. As the dog’s owner, stay calm. Panic will only make the situation worse.
  2. Don’t get between your dog and the other dog(s) to break up the fight. You could also get bit in the process.
  3. Focus on getting your dog away from the other dog. A loud clap or another distracting sound may help get your dog’s attention so you can call or signal him to you.
  4. Don’t scream at the other dog, as this could make the situation feel even more threatening to the dogs.
  5. Ask the other dog owner (if present) if their dog is up to date on their vaccines. If the pet owner isn’t present or the other dog involved is a stray, try to get pictures at the very least.
  6. Once your dog is safely away from the dog who bit him, contact your vet immediately or head to your nearest emergency animal hospital.

Why Do Dogs Bite?

Biting is often part of play for puppies. In adult dogs, multiple motives or causes for biting can stem from competitive issues or reactions to perceived threats. Additionally, several factors influence the severity of a dog bite and the health risk it can pose to a pet. This is why seeing your veterinarian as quickly as possible after your dog has experienced a bite is a good idea.

Treating Bite Wounds in Dogs

Dog bites can cause significant injury to the skin and soft tissues. A dog’s teeth and jaws are powerful; a bite wound can result in torn muscles and skin. Not all bite wounds are big, though. Just because a bite wound is small doesn’t mean it isn’t a cause for concern. Minor bites can heal themselves quickly but, in doing so, can trap bacteria in the wound that can result in an abscess.

Infections are the primary concern for any dog bite, but other serious issues can develop if not treated properly. Typically, a vet will examine and thoroughly clean the bite wound and then provide a broad-spectrum antibiotic to help fight infection and prevent further complications with the wound site. Or, the vet can use Vetrix’s Healion Amniotic Wound Matrix as part of their patient’s bite wound treatment plan. 

Healion is a decellularized amniotic membrane supplied in fine, dry, sterilized white powder form for veterinary use. Healion amniotic wound matrix leverages the natural healing properties of the amnion to modulate inflammation and create an environment conducive to rapid cell migration.

You apply it to the wound site and appropriately bandage it to create a sterile healing environment. The bite should be re-examined every 4-5 days, and a single application is usually sufficient.

Corneal Ulcer Dog Treatment

The canine eye is much more resilient than a lot of people would expect to trauma, but this is still one of the most at-risk parts of the dog’s body. For this reason, corneal ulcers are quite the common reason for a visit to the vet.

While common, corneal ulcers should never be treated as a general situation that does not require veterinary or medical intervention. If the ulcer does not heal properly, the dog’s visual capabilities can be affected. Below, we will take a look at what a corneal ulcer actually is, what causes it, and how the condition may be treated.

Ask Your Veterinarian About This

What Is the Cornea of a Dog’s Eye?

The cornea, simply put, is the thin membrane that covers the forward-facing part of the eyeball. The membrane is completely transparent, almost like a window that protects the inner structures of the eye. The full cornea is about half as thick as a dime.

The dog’s cornea, much like a human’s cornea, is made up of different layers: the outer layer of epithelium, the interior layer of stroma, and the Descemet membrane at the deepest point. All three layers of the cornea are clear, making it impossible to discern between them with the naked eye. In order to examine the cornea, veterinarians use special pigmented eye drops with a green dye that highlights cells of specific layers of the cornea.

What Is a Corneal Ulcer?

Corneal ulcers are abrasions (sores) of the outer surface of the eye that protects the pupil, iris, and aqueous humor. Medically, corneal ulcers may be referred to as ulcerative keratitis. The abrasion causes inflammation, swelling, and can be slow to heal depending on the depth of the trauma. The ulcers in a dog’s cornea can range in severity from superficial to deep, depending on which layers of the cornea are injured.

Types of Corneal Ulcers in Dogs

Corneal ulceration can be superficial or a deeper problem that reaches into the corneal stroma, and sometimes all the way into the Descemet’s membrane. Here is a more thorough explanation of some of the types of corneal ulcers that dogs can have.

Superficial Ulcers

Superficial ulcers are sometimes referred to as superficial corneal abrasion or corneal erosion, and they affect only the epithelium layer. Superficial corneal ulcers are the easiest to treat and often do not require medical intervention to heal properly. However, topical antibiotics for the corneal surface may be vet-recommended until the ulcer heals.

Stromal Ulcers

Stromal ulcers affect the corneal stroma and can be much more threatening to the eye and the dog’s comfort level. The stroma is actually laced with nerves, which means damage to this layer of the cornea can bring about significant pain for the dog. Stromal ulcers take longer to heal than superficial corneal abrasions, and medical intervention with antibiotic eye drops is often a must to prevent infection.

Descemetoceles and Perforations

Ulcers that reach into the Descemet’s membrane are referred to as descemetoceles. When an ulcer actually goes completely through the Descemet’s membrane, this is referred to as corneal perforation. 

Both descemetoceles and perforations may need to be surgically treated in an effort to preserve the eye, even though an aggressive effort to medicinally manage the problem may suffice for some dogs. Serious complications, such as vision loss and a need to remove the eye are more common with these types of ulcers.

Indolent Ulcers

Indolent ulcers, which are also referred to as spontaneous chronic corneal epithelial defects (SCCEDs), are non-healing ulcers that are usually caused by trauma. These ulcers are more common in older dogs, most often diagnosed around eight or nine years of age. 

Even though by definition an indolent ulcer is superficial, sometimes, an indolent ulcer will actually get infected and affect the stroma. With this particular type of ulcer, improper healing can be to blame; the surface layer epithelium can actually be loosely attached to the underlying stroma.

How a Corneal Ulcer Occurs

Corneal ulcers in dogs can occur for several reasons, even though the biggest causative factor is usually some type of trauma to the dog’s eye. A dog’s eye may sustain trauma by a direct, blunt hit to the eye, foreign material under its eyelid, and even just by scratching with its own paws and nails.

A few other causes of corneal ulcers in dogs include:

  • Illness or disease
  • Lacking tear production
  • Eyelid rolling or inability to close the eyelids
  • Chemical burns
  • Eye infections
  • Facial nerve paralysis that affects eyelid movement

Some dog breeds can actually be more prone to corneal ulcers than others due to the shape of their eyes and the surrounding lids. For example, breeds with shorter noses and prominent eyes that seem to protrude a bit from the face like Pugs and Boxers, are more likely to sustain corneal ulcers.

Signs and Symptoms of a Corneal Ulcer in Dogs

One of the good things about corneal ulcers is the fact that most dog owners will readily recognize that something is wrong with their dog’s eye so they can seek veterinary care. A few signs and symptoms during the initial stages of a corneal ulcer include:

  • Ocular discharge
  • Squinting
  • Sensitivity to light
  • Watery eyes
  • Pawing at the eyes
  • Holding the eye closed
  • Redness or inflammation of the eye
  • Film development over the eye

Usually, dogs will show signs that their eye is injured or causing problems a lot during the first few days after the trauma occurs.

How Does a Corneal Ulcer Affect Your Dog?

Dogs with corneal ulcers may be affected in different ways depending on the severity of the condition. Sometimes, a surface-layer abrasion won’t seem to make much of a difference to the dog or the dog’s ability to see and get around. However, deeper abrasions can be painful and have a higher likelihood of affecting the dog’s vision.

Even though trauma to the eye is assumed to always be painful, this may not be the case with every corneal ulcer. While the issue can be recognizable upon visual inspection, injury to the corneal surface may only cause some slight discomfort, so a dog may not be in pain or show any major signs of distress.

Unfortunately, however, some corneal ulcers can be painful. As noted above, abrasions that go deeper than the corneal epithelium can be extremely uncomfortable for the dog. The vet may offer pain-relieving eye drops because of this.

Can a Dog Go Blind from a Corneal Ulcer?

Dogs can lose their vision to a corneal ulcer, especially if the condition is left untreated or if the proper steps are not taken to promote healing. For example, if the dog has a stromal ulcer, which carries a high risk of infection, and the condition is left untreated with antibiotic drops and gets infected, the chance the dog will lose its sight is high.

Another important factor, a scar on the surface of the cornea that develops during the healing process can lead to corneal opacity. This makes part of the eye appear as if it has clouded over, but it also makes it impossible for light to properly get to the optic nerve. Therefore, the dog’s visual capacity can be affected. In some cases, the right treatments during the healing process can help deter heavy scar formation.

Corneal opacity caused by scarring after an ulcer should not be confused with corneal dystrophy. Corneal dystrophy also causes opacity, but this is a result of some kind of genetic malfunction that interferes with how the dog’s body metabolizes fat. Fatty deposits can collect in the eye and cause similar cloudiness that impedes visual capacity over time.

Typical Corneal Ulcer Dog Treatment

Treatment for corneal ulcers in canines depends on the type of ulcer diagnosed. General corneal abrasions may need no treatment at all; the mild abrasions may heal on their own within a few days. Nevertheless, medication may be used as a preventive measure to prevent an ophthalmic infection. Some of the more typical methods of treating corneal ulcers include:

  • Antibiotic eye drops
  • Topical antibiotic ointments
  • Eye drops with a pain reliever

When surgery is necessary to treat a corneal ulcer, a few different procedures may be used. For example, corneal diamond burr debridement surgery is a procedure performed with a diamond burr that gently removes the damaged corneal tissue to promote proper healing.

Regenerative Care for Canine Corneal Ulcers

Treating corneal defects is not an easy feat; so many things can inhibit the healing process and cause problems for the dog’s vision for the long term. Ideally, treatment would help the corneal tissue regenerate and repair itself with little disruption to the dog’s vision. Therefore, a more modern inclusion tactic in the treatment of corneal ulcers is using regenerative solutions.EyeQ Eye Drops from Vetrix is an easy way to offer regenerative care to the dog’s eye. These amniotic eye drops utilize innate growth factors and other components that modulate inflammation, offer just enough lubrication for protection, and promote healing by encouraging cellular growth.

Dr. Herrington- August’s Featured Case

August 2018

This months’ case comes to us from Dr. Mike Herrington DVM. He leverages Healion, Vetrix’s amnion wound particulate to close a mass removal.

Dr. Herrington practices at Englewood Animal Health Center in Englewood, FL. Read below to learn why he used Healion and his results utilizing this technology.

Case background: “Gracie is a 6yr old F/S Boxer mix who presented for removal of about a 1.5cm dermal mass on the dorsal mid shaft R forelimb. The mass removal was the easy part, but closure was difficult. The mass was directly over the cephalic vein, so I did not want to leave it open. I had to undermine completely around the circumference of the leg and make about 2 dozen mesh incisions, as well subQ anchors just to get the skin apposed. Even so it was tight, so I splinted it and applied a modified Robert Jones bandage. I performed daily wet-dry bandage changes, using Entederm (nystatin-neomycin-triamcinolone) ointment, mainly for the anti-inflammatory properties. The skin just didn’t stretch as much as I was hoping, and the cephalic vein was being compressed, so her foot became edematous and the skin around the incision is showing some focalized necrosis. On April 7th I made 2 releasing incisions under bupivicaine, taking great care to leave the cephalic vein covered. I was able to massage a good amount of the edema out. I replaced the splint & bandage, this time switching to silvadene cream. She is also on carprofen and cephalexin orally BID.” – Dr. Herrington

Initial Healion Application

Healion was initially applied on 4/11/18, 8 days after surgery, to the releasing incision sites. Gracie got her bandage off 3 days later and licked the Healion off the wound.

Reapplying Healion

Healion was reapplied per suggestion from Vetrix on 4/16/18. No further complications occurred.

4 Days Post Second Application

Healing proceeded well, a healthy granulation bed formed by 4/19/18. The splint was removed from the bandage on 4/20/18 (4 days post Healion application), with Gracie able to fully bear weight on the affected leg.

5/4/2018 (18 Days post Healion application)

Bandaging was maintained to protect the healing wound.

5/14/2018 (28 days post Healion application)

Epithelialization proceeded well, and was complete on 5/14/18. Carprofen and cephalexin therapy was maintained until 5/14/18.
