Why Is My Dog’s Wound Bleeding After It Seemed to Be Healing?

Overview
If your dog's wound starts bleeding again after it seemed to be healing, it may simply have been rubbed, licked, bumped or reopened as the skin tightened. It can also happen if the wound is irritated, infected, or if a scab has lifted too early. You can't tell the exact cause just by looking, but you can check for signs that help you judge how urgent it is.
Things To Check
1. See whether the bleeding started after exercise, play, getting wet, grooming or licking.
2. Look for swelling, heat, redness, discharge, a bad smell or extra soreness around the wound.
3. Check whether the wound has opened up again, or whether a scab has been pulled off.
4. Notice if your dog is licking, chewing or scratching the area more than before.
5. Look at the amount of bleeding. A small fresh spot is different from steady bleeding or blood soaking through dressings.
6. Check for dirt, hair, debris or damp fur around the wound that could be irritating it.
7. Watch your dog for changes in comfort, appetite or energy, which can go along with a wound that isn't settling properly.
Common Causes
The most common reason is simple re-injury. A wound that was starting to close can open again if it's rubbed on bedding, tugged during play, or licked enough to soften the scab.
Irritation is another common cause. Moisture, dirt, grooming, or movement over a busy area such as a leg or paw can make fragile healing skin bleed a little.
Infection can also slow healing and make the wound more likely to ooze, bleed or look angrier than before. You may also notice discharge, smell or swelling.
Less commonly, a deeper wound, a foreign body, or a problem with normal clotting can make bleeding harder to settle. These are not things you can safely rule out at home.
What To Do
If the bleeding is light, keep the area as still and clean as you can. Stop your dog licking or scratching it, and avoid letting them run, jump or go straight back into rough play.
Gently check the wound without picking off scabs or scrubbing the skin. If the fur is trapping dirt or moisture, carefully keep the surrounding area tidy so you can monitor it better.
Watch the wound over the next few hours. If it keeps reopening, looks more swollen, starts to smell, or seems more painful, it's sensible to get veterinary advice rather than waiting it out.
If bleeding becomes heavier, won't stop, or your dog seems unwell, seek veterinary help promptly.
When To Contact A Vet
Contact your vet if the wound is bleeding repeatedly, opening back up, producing discharge, or looking swollen, hot or painful. You should also get advice if your dog seems off colour, won't leave the wound alone, or the skin doesn't seem to be improving over a day or two.
Get urgent help if the bleeding is heavy, the wound is deep, or your dog seems weak, distressed or unwell.
