Overview
If your dog’s wound edges are pulling apart, the main thing to do is keep the area clean, protected and still, then have it checked by a vet if it looks open, dirty, painful or is getting worse. There can be several reasons for this, including movement, licking, swelling, infection or a wound that hasn’t been able to heal well.
Things To Check
1. Check whether the gap has changed since you last looked at it, especially after exercise, licking, or a nap.
2. Look for redness, swelling, heat, discharge, bad smell, bleeding or skin that looks wet and sore.
3. See whether your dog is licking, scratching, rubbing or chewing at the wound.
4. Check if the wound is in a place that moves a lot, such as near a joint, shoulder, neck or paw.
5. Think about whether the wound may have been caught on bedding, grass, furniture or a lead.
6. Notice if your dog seems more painful than before, is less keen to move, or is guarding the area.
7. Check whether there are any stitches, clips or dressings in place, and whether they look loose, dirty or damaged.
8. Consider whether your dog has a habit of slowing healing, such as by repeatedly worrying at the area or being very active.
Common Causes
The most common reason is simple wound tension. If the skin is being stretched by movement, swelling or location, the edges can start to separate.
Licking, scratching or rubbing is another common cause, because it can irritate the area and stop it settling.
Infection can also make a wound break down, especially if there is discharge, smell, heat or increasing soreness.
Sometimes the wound was deeper than it first looked, or there may have been hidden bruising or dead tissue that makes healing slower.
Less commonly, an underlying health issue or poor blood supply to the area may make closure and healing more difficult.
What To Do
Keep your dog calm and limit running, jumping and rough play so the wound is not being stretched further.
Stop licking or chewing if you can. An e-collar or other vet-approved barrier may help prevent more damage.
Keep the area clean and dry unless your vet has already given different instructions. Avoid using creams, sprays or home remedies unless you know they are suitable for the wound.
If the wound has reopened, is bleeding, or looks dirty, cover it lightly with a clean dressing only if you know how to do so safely, then arrange veterinary advice.
Keep an eye on how it looks over the next few hours. If the edges keep pulling apart, the gap widens, or it starts to look more sore, it needs a proper check.
When To Contact A Vet
Contact your vet promptly if the wound edges are separating, the wound is open, or the area is getting red, swollen, hot, smelly or painful. Get advice sooner if your dog has stitches or clips, the wound is near a joint, or your dog seems unwell.
If the wound has fully opened, is bleeding heavily, or you can see deeper tissue, treat it as urgent.
