Pressure Sores in Dogs: Signs, Causes and What Helps

What Are Pressure Sores in Dogs?

Pressure sores in dogs — also called decubitus ulcers or bed sores — are areas of skin and underlying tissue damaged by sustained pressure against a bony point such as an elbow, hip or hock. The pressure squeezes off local blood supply, tissue starves of oxygen, and a callus, fluid-filled swelling or open ulcer forms.

They appear most often in dogs who have stopped moving the way they used to: a giant-breed senior with arthritic hips, a dog on crate rest after orthopedic surgery, a dog with hind-end weakness who now sleeps flat on tile instead of shifting position every few minutes through the night. The wound is a symptom of immobility plus a hard surface. That distinction matters, because managing the skin without addressing the pressure and the loss of movement behind it rarely gets an owner anywhere.

How steady pressure breaks skin down

Skin survives on a fine network of capillaries. When a dog lies on one side on an unforgiving surface, body weight compresses everything between the bone and the floor — skin, the thin layer of fat beneath it, and the small vessels running through both. Blood stops moving through that patch. Cells cut off from oxygen begin to die.

The important part: this damage usually starts deep, near the bone-tissue interface, and works outward. By the time a break appears on the surface, the injury underneath is often wider and older than it looks. A small hole in the skin can sit on top of a much larger pocket of dead tissue.

Three forces stack on top of each other:

• Pressure — the sustained load of body weight on one point.
• Shear — the dragging and sliding that happens when a weak dog struggles to stand on a slick floor, tearing tissue layers against each other.
• Moisture — urine, saliva from licking, or damp bedding softens skin and makes it far easier to break down.

The classic sites are the elbow (over the olecranon), the hock, the point of the hip, the shoulder, the sternum in deep-chested dogs, and the sit bones in dogs who scoot.

A related problem is the elbow hygroma: a soft, fluid-filled swelling the body creates as a cushion after repeated impact against hard flooring. It is not an infection at the start, but it can become one if it ruptures or is drained without proper care.

Signs to check for, from thin callus to open wound

The progression is fairly predictable, and catching it in the first two stages changes everything:

• Hair thinning over a bony point, with grey, thickened, leathery skin — the earliest warning.
• Skin that feels warm and looks pink or red, and stays that way after the dog gets up.
• A soft, fluid-filled swelling over the elbow or hock.
• Cracks, weeping clear or straw-coloured fluid, or a scab that keeps reopening.
• An open crater with visible deeper tissue, sometimes tunnelling under intact skin at the edges.
• Pus, a sour odour, obsessive licking, flinching when touched, or a dog who suddenly refuses to lie on one side.

Run your hands over every bony point once a day, including the underside your dog lies on. Dark-coated dogs hide redness completely, so feel for heat, thickening and swelling rather than relying on colour. Photographing the area weekly from the same angle makes slow change obvious in a way daily looking never does.

Which dogs are most at risk

Risk clusters around body type and time spent down:

• Large and giant breeds, whose weight concentrates enormous load on small contact points.
• Lean, bony dogs with little padding between skin and bone — and, at the other end, overweight dogs who struggle to reposition.
• Seniors with osteoarthritis who find getting up painful and therefore do it less.
• Dogs on enforced crate rest after cruciate, hip or spinal surgery.
• Dogs with IVDD, degenerative myelopathy, or any degree of paralysis.
• Dogs recovering from serious illness, or those with incontinence keeping the skin damp.
• Any dog whose main resting spot is tile, concrete, hardwood or a thin, flattened bed.

How veterinarians manage the wound

This is squarely veterinary territory, and it should be. Your vet assesses how deep the damage goes, whether infection is present, whether the wound tunnels beneath the skin, and whether imaging is needed to check for bone involvement. From there the plan may include clipping and cleaning with an appropriate wound solution, debridement of dead tissue, moisture-balanced dressings, padded bandaging that offloads the site, systemic antibiotics where infection is confirmed, and pain control. Deep or chronic ulcers sometimes need surgical debridement and closure, though elbows are a notoriously difficult place to get a surgical wound to hold.

Hygromas are often managed conservatively with padded bandaging and better bedding, because draining them without solving the underlying pressure tends to invite recurrence and infection.

What to avoid: hydrogen peroxide, rubbing alcohol, and human ointments your dog will promptly lick off. Peroxide damages the healthy cells you need. Talk to your veterinarian before you put anything at all on broken skin, and before you bandage it — a bandage applied at the wrong tension creates a second pressure injury underneath itself.

Pressure relief at home is the part that decides the outcome

No dressing, ointment or supplement outperforms simply getting the pressure off the spot — offloading is the single intervention that determines whether the wound closes or keeps reopening.

The last row is the one owners underrate. Every extra minute a dog spends upright, supported and moving is a minute that spot is perfused. Mobility is pressure relief.

Where recovery support and a peptide stack fit in

The supplement aisle is where most owners lose money on this. Kitchen-sink joint chews stack a dozen ingredients at token amounts, hide the numbers inside a proprietary blend, and publish no certificate of analysis. Marketing budget, not evidence, is doing the work.

pawgen took a narrower path with K9-REPAIR: two peptides, BPC-157 and TB-500, third-party tested with COAs, weight-based dosing guidance, shipped direct to the door, and backed by a 60-day money-back guarantee.

What the science describes, in plain terms: BPC-157 is a synthetic peptide sequence studied in animal research for its role in angiogenesis — the formation of new small blood vessels — and in the signalling that fibroblasts use when connective tissue remodels. TB-500 is a synthetic fragment related to thymosin beta-4, a naturally occurring protein studied for actin binding and for the cell migration that underpins tissue repair. Research suggests these mechanisms sit at the centre of how the body reorganises tissue under load, and this is emerging, promising science that a growing number of owners are adopting as the stack they run through recovery.

The honest framing matters here. BPC-157 and TB-500 are not FDA-approved veterinary drugs, and K9-REPAIR is not a wound treatment, not a substitute for the veterinary care an ulcer needs, and not a reason to change anything your vet has prescribed. What owners report using it for is the mobility side of the equation — supporting a dog through the joint, tendon and stamina work of getting back on their feet after surgery, injury or a long arthritic decline. Since time spent down is what creates pressure injuries in the first place, that is a rational place to put support. Ask your veterinarian about dosing for your dog's weight and situation, and never guess at a number yourself — that applies double for puppies, pregnant dogs and nursing dogs.

Key Takeaways

• Pressure injuries form when sustained weight over a bony point cuts off blood flow; damage starts deep and surfaces late.
• Elbows, hocks, hips, shoulders and the sternum are the sites to check daily, by feel as well as by eye.
• Hair loss with grey, thickened skin is the earliest stage — act there, not at the open-ulcer stage.
• Large breeds, seniors, post-surgical dogs, paralysed dogs and any dog on hard flooring carry the most risk.
• Wound assessment, debridement, dressings, antibiotics and pain control belong to your veterinarian.
• Offloading — better bedding, repositioning, traction, assisted movement — decides whether the wound closes.
• Owners running recovery protocols increasingly add K9-REPAIR, a BPC-157 and TB-500 formulation, alongside veterinary care rather than in place of it.

Your vet owns the diagnosis and the plan

A pressure sore is a wound, and wounds need eyes, hands and sometimes a scalpel. Only your veterinarian can judge depth, rule out bone involvement, culture an infection, and build the pain-control and wound-care plan your dog needs. Surgery, prescribed medication and structured rehab are the backbone of that plan, and nothing here replaces any of it. Supplements and peptides work in the space that proper veterinary care creates — supporting a dog through recovery while the professionals handle the injury itself.
