Vets use bandages on many kinds of wounds. A bandage protects the wound surface, holds dressings in place and helps control the fluid a wound makes [2]. This guide explains why your vet may bandage your pet and which bandage problems vets watch for. It does not replace your vet’s own instructions.
Do not remove or change a bandage unless your vet says so. Call your vet if a bandage seems too tight or is wet or soiled with urine or feces.
Why vets use bandages
Depending on the wound, a bandage can help to:
- protect the wound from more injury and from dirt [2];
- keep the wound at the right level of moisture, neither drying out nor soaking wet [2];
- soak up fluid that seeps from the wound [2];
- hold dressings on the wound with even pressure [2];
- help the body clear dead tissue from the wound bed, as some dressings that hold in moisture do [2];
- support and steady a leg, when a splint is built into the bandage [1].
A recent case report in a dog describes wound care that balanced moisture and controlled wound fluid, with the wound slowly filling in and closing over several months [2]. For how a wound heals, see how wounds heal in dogs and cats.
For why vets close some wounds and leave others open, see stitched or left open wounds in dogs and cats.
Why bandaging is your vet’s job
Bandages and splints are not risk free and can hurt the tissue under them [1]. The pressure a bandage puts on the skin is hard to get right. In a University of Minnesota study, a second person put back the same custom splint on dogs’ hind legs, and the pressure under the bandage changed by a meaningful amount in 10 of 11 legs [1]. The pressure also shifted when the dog stood up or lay down [1]. Your vet chooses the bandage for your pet’s wound and checks it at each change.
Problems vets watch for
- Too much pressure: pressure on the skin can cut the blood flow to the tissue under it. If it lasts, a patch of tissue can die and form a pressure sore [1]. Bony points, such as the ankle or wrist, seem to get these sores more often [1].
- Skin damage: problems linked to bandages include swelling, redness, scrapes and inflamed skin [1].
- Moisture: a wound needs the right moisture balance to heal [2], and in people, moisture on the skin is one of the things that raises the risk of pressure injury [1]. A bandage that is wet or soiled with urine or feces needs your vet’s attention.
The same study notes that owners spot bandage injuries only about one time in five [1]. That is why the rechecks your vet books matter. For how tight bandages can slow healing, see slow-healing wounds in dogs and cats.
At home, as directed by a vet
- do not remove or change a bandage unless your vet says so;
- keep the bandage clean and dry, and care for it only in the way your vet shows you;
- go back for every bandage change and recheck your vet books.
When to call your vet
Call your vet if your dog or cat has a bandage that:
- seems too tight, or the skin around its edges looks swollen, red or sore [1];
- is wet, or has urine or feces on or in it.
The bottom line
Vets use bandages to protect wounds, hold dressings in place and keep the wound’s moisture in balance. Too much pressure, skin damage and moisture are the main bandage problems, and owners often miss them. Only your vet should put on or change a bandage, and your vet will advise on care.
