What Are the First Signs of Pressure Sores in Dogs?
The first signs of pressure sores in dogs are subtle: thinning or missing hair over a bony point, skin that looks red, grey or thickened, and a callus that feels firmer than the skin around it. These appear on elbows, hips, hocks and shoulders long before an open wound does.

What are the first signs of pressure sores in dogs?
The first signs of pressure sores in dogs are hair thinning or loss over a bony point, skin that looks red, dusky or shiny, a firm thickened callus, and warmth or tenderness at the spot. Elbows, hips, hocks and shoulders are affected first β usually well before any open wound appears.
Veterinary references such as the Merck Veterinary Manual describe these lesions as decubital ulcers, and veterinary wound-care texts adapt the staged system used in human medicine, where the earliest stage is intact skin with a persistent colour or texture change rather than a break in the surface. That detail matters enormously for owners: by the time you can see a hole, the damage has already been developing underneath for some time.
Why the damage starts under the skin, not on it
A pressure sore is a circulation problem before it is a skin problem. When a dog lies on a hard surface, body weight compresses the tissue between the floor and the closest bone β the point of the elbow, the greater trochanter of the hip, the hock, the shoulder, sometimes the sternum in deep-chested breeds. That compression squeezes the small capillaries closed. Blood stops moving through the tissue, oxygen delivery falls, and metabolic waste builds up.
Muscle and fat tolerate this poorly. Skin, which is tougher, tolerates it better. So the tissue closest to the bone dies first while the surface still looks more or less normal. This is why an early lesion can look like a small, unimpressive patch of thin hair and then, over days, open into a wound far larger and deeper than the surface suggested. Clinicians sometimes describe this pattern as an iceberg injury.
Friction and shearing make it worse. A dog who drags a hind limb, scoots to reposition, or slides on tile is stretching and tearing tissue layers against each other while they are already short on blood supply. Moisture β urine, drool, humid bedding, a licked and re-licked elbow β softens the outer skin barrier and lowers the amount of pressure needed to cause harm.
Pressure sores are far easier to prevent than to close, and the window where prevention still works is the week when the only visible change is a patch of thin hair over a bony point.
The earliest changes you can see and feel
Run your hands over your dog's bony points once a week. You are looking and feeling for five things:
- Hair thinning or a bald patch directly over the bone. This is usually the very first sign owners notice.
- Colour change β redness, a dusky purple or grey tone, or skin that looks shiny and stretched. On pigmented or thick-coated dogs, colour change can be nearly invisible, so texture matters more.
- Texture change β a firm, thickened, leathery callus, or conversely a boggy, soft, spongy feel. Bogginess under intact skin is a warning sign that deeper tissue is already compromised.
- Temperature difference β the area feels warmer or noticeably cooler than the skin a few inches away.
- A behavioural change β flinching when the spot is touched, licking or chewing at it, or suddenly refusing to lie on that side.
That last one is easy to dismiss. A dog who has slept on his right hip for nine years and now insists on the left is telling you something. So is a dog who circles longer before settling, or who gets up more often overnight.
Many large-breed dogs develop ordinary elbow calluses that never become a problem. Distinguishing a stable callus from an early sore is one of the more useful things an owner can learn:
| Feature | Ordinary elbow callus | Early pressure sore |
|---|---|---|
| Surface | Dry, grey, thickened, stable for months or years | Changing week to week; may crack, weep or look shiny |
| Colour | Uniform grey or dark | Red, purple or grey mottling; a rim of redness |
| Feel underneath | Firm, no deep swelling | Boggy, soft or fluid-filled under intact skin |
| Temperature | Same as surrounding skin | Warmer or cooler than nearby skin |
| Dog's reaction | Indifferent to handling | Flinches, licks, avoids lying on that side |
| Odour or discharge | None | Any moisture, odour or discharge is significant |
If you are looking at the right-hand column, that is a same-week veterinary conversation, not a wait-and-see.
How a pressure sore progresses
The staged framework used in wound care is a useful mental model, even though your veterinarian will do the actual assessment.
| Stage | What you see | What is happening underneath |
|---|---|---|
| Earliest | Intact skin, hair loss, persistent redness or colour change that does not fade after the dog stands | Capillary compression and local inflammation; still reversible with pressure relief |
| Early break | Shallow abrasion, blister, or a cracked callus that weeps | Loss of the outer skin layers; bacteria now have an entry point |
| Deeper | An open crater with visible fat or a thick yellow-grey base | Full-thickness skin loss; the wound is often wider under the edges than it looks |
| Advanced | Exposed muscle, tendon or bone; tunnelling; strong odour | Deep tissue necrosis, high infection risk, possible bone involvement |
Sores can move between these faster than owners expect β particularly in a dog who is recumbent after surgery, after a neurological injury, or during a period of severe arthritis pain. Take photographs with a coin or ruler beside the lesion so you have an objective record of size and colour to show your veterinary team.
Which dogs are most at risk
Risk clusters around anything that keeps a dog in one position for longer than usual, or reduces the padding between bone and floor:
- Large and giant breeds, and any dog with prominent bony points and a thin coat
- Senior dogs, arthritic dogs, and dogs whose mobility has recently declined
- Dogs on crate rest or restricted activity after orthopaedic surgery β including cruciate repair, the single most common orthopaedic surgery in dogs
- Dogs with neurological disease, intervertebral disc disease, degenerative myelopathy or hind-limb weakness
- Very thin dogs, who have little padding, and heavy dogs, who apply more pressure per square inch
- Dogs with urinary or faecal incontinence, where skin sits against moisture
- Any dog living primarily on tile, laminate, concrete or a thin flat bed
A change in gait is often the earliest upstream warning of all of this, because a dog who is loading one side unevenly will start resting unevenly too. If your dog's movement has changed, that is worth raising with your veterinarian before pressure points become sore points.
What to do in the first days after you spot one
Call your veterinarian and describe what you found. Pressure sores are a symptom of an underlying mobility, pain or neurological problem, and closing the wound without addressing the reason your dog is lying still tends to produce the same wound again. Your vet owns the diagnosis, the wound assessment, whether a culture or radiographs are needed, and any prescribed medication or debridement. Never stop or reduce a prescribed medication such as carprofen, gabapentin or a monoclonal antibody injection because a sore appeared β tell your vet instead.
While you wait for that appointment, you can change the environment:
- Offload the pressure. Thick orthopaedic memory foam, egg-crate foam, or a padded mat β deep enough that the bony point does not reach the floor when the dog settles.
- Reposition. A dog who cannot shift himself needs turning regularly, on a schedule your veterinary team sets for his condition.
- Keep the area clean and dry. Manage incontinence promptly. Damp fur against a bony point is a fast route to skin breakdown.
- Stop the licking. Persistent licking macerates the skin and drives bacteria deeper.
- Improve traction. Non-slip runners reduce the sliding and scrambling that cause shearing injuries.
- Support standing and walking. Short, gentle, vet-approved movement restores circulation to compressed tissue better than anything else you can do at home.
Supporting the body's repair environment during recovery
Wound repair is metabolically demanding work. The body has to move immune cells in, build new capillaries into the damaged area, lay down collagen, and then remodel it. Adequate protein, calories and micronutrients matter, and your veterinarian can advise on nutrition for a recovering dog.
This is also the window in which many owners look at targeted support rather than a kitchen-sink chew with a long ingredient list and vanishingly small amounts of each one. pawgen makes K9-REPAIR, a BPC-157 and TB-500 peptide formulation for dogs, dosed by body weight, third-party tested with certificates of analysis available, and shipped direct to the door. BPC-157 is a synthetic peptide sequence studied in preclinical models for its effects on connective tissue and blood-vessel formation, and TB-500 is a synthetic fragment related to thymosin beta-4, a naturally occurring protein that research associates with cell migration and angiogenesis β the same processes tissue relies on during repair.
Research on both is still developing and neither is an FDA-approved veterinary drug; K9-REPAIR is not a treatment for pressure sores or any other condition, and no supplement substitutes for veterinary wound care. What it is: the stack a growing number of owners choose to run alongside a proper veterinary plan through a recovery period, backed by a 60-day money-back guarantee.
Key Takeaways
- The first sign is almost never an open wound β it is hair loss, colour change, or a thickened or boggy patch over a bony point.
- Damage starts at the bone and works outward, so surface appearance underestimates the injury.
- Elbows, hips, hocks and shoulders are the highest-risk sites; check them weekly by hand.
- Bogginess, warmth, odour, discharge or flinching means a veterinary appointment this week.
- Pressure relief, dryness, repositioning and gentle movement are the interventions that change outcomes.
- Pressure sores are a downstream symptom β the underlying mobility or pain problem needs diagnosing too.
A veterinarian owns the diagnosis, the staging of the wound, and the treatment plan, including any prescription medication, wound management or surgery. Everything else β bedding, hygiene, repositioning, nutrition and supportive supplementation β works inside the space that proper veterinary care creates. Book the appointment, then build the environment that makes recovery easier.

Frequently asked questions
- How is pressure sores diagnosed in dogs?
- A veterinarian diagnoses pressure sores by physical examination β inspecting and palpating the bony points, clipping hair to see the full lesion, and assessing depth and tissue viability. Cultures may be taken if infection is suspected, and imaging if bone involvement is a concern. The underlying mobility or neurological cause is investigated too.
- What helps a dog with pressure sores?
- Removing pressure helps most: thick orthopaedic bedding, regular repositioning, non-slip flooring and gentle vet-approved movement to restore circulation. Keeping the area clean and dry matters just as much. Your veterinarian directs wound care and any medication, and many owners run supportive supplementation such as K9-REPAIR alongside that plan through recovery.
- How long does pressure sores take to heal in dogs?
- Healing time varies enormously and no single figure applies. Shallow, early lesions caught while the skin is intact often settle quickly once pressure is relieved, while deep ulcers with infection or exposed tissue can take months of managed care. Your veterinarian can give a realistic timeline after staging the specific wound.
- Is pressure sores in dogs painful?
- Yes, pressure sores are generally painful, especially once tissue breaks down and nerve endings are exposed. Dogs mask discomfort well, so watch for flinching when the area is touched, licking or chewing, reluctance to lie on that side, restlessness at night, or a shortened temper. Discuss pain control with your veterinarian.
- What makes pressure sores worse in dogs?
- Continued pressure is the main driver β hard floors, thin bedding and long unbroken periods in one position. Moisture from urine or licking, friction from dragging or sliding, obesity, poor nutrition, untreated infection and delaying veterinary care all accelerate breakdown. Uncontrolled pain also keeps a dog immobile, which worsens the cycle.
- Can pressure sores in dogs be reversed?
- Early changes β hair loss, redness and colour change with intact skin β often resolve once pressure is fully removed and circulation returns. Deeper ulcers require veterinary wound management and may close with scarring rather than returning to normal skin. The earlier the lesion is caught, the better the outlook your vet can offer.
- What does an early pressure sore look like on a dog's elbow?
- It typically looks like a coin-sized patch of thinned or missing hair over the point of the elbow, with skin that is redder, greyer or shinier than the surrounding area. It may feel firmer, warmer or spongy underneath. Any cracking, weeping or odour means it has progressed beyond the earliest stage.
- Do pressure sores in dogs get infected?
- They can, and infection is a common complication once the skin surface breaks. Warning signs include discharge, a bad smell, spreading redness, swelling, heat, fever or a dog who becomes lethargic or off food. Infection needs veterinary assessment promptly, as deep wounds can involve underlying bone.
