Overview
If your dog is licking an infected wound, it’s usually because the area feels sore, itchy, sticky or irritating. Licking can also be a habit once a wound has become uncomfortable. There can be several causes, so it’s best to look at the wound carefully rather than assume it’s just normal behaviour.
Things To Check
1. Check whether your dog is licking more after rest, exercise, grooming, or when they’re left alone.
2. Look closely for redness, swelling, heat, discharge, a smell, or skin that looks wetter than before.
3. See if the wound edges are opening, the scab keeps being removed, or fresh blood appears after licking.
4. Check whether your dog seems bothered when the area is touched or when they move nearby joints.
5. Look for signs of spread such as a larger area of redness, new swelling, or the surrounding skin becoming more painful.
6. Consider whether flies, dirt, mud, bedding, or a collar could be irritating the area.
7. Note any changes in your dog’s behaviour, appetite, energy, or willingness to move normally.
Common Causes
The most common reason is that the wound is uncomfortable. Infection can make skin sore, inflamed and itchy, which often leads to more licking.
Licking can also happen because the wound is healing and the area feels tight, dry or irritating. Even if healing is underway, repeated licking can make things worse by delaying drying and keeping the skin moist.
Sometimes the wound isn’t the only issue. A trapped foreign body, dirty coat, matted fur, or another skin problem nearby can keep the area irritated and encourage licking.
Less commonly, a wound that looks like a simple sore may be deeper, more painful, or affected by an underlying problem that needs veterinary assessment.
What To Do
Try to stop the licking as far as you safely can, because repeated licking often irritates the wound further. Keep the area clean and dry, and follow any wound care advice you’ve already been given.
Check the wound at least once or twice a day so you can spot changes early. If the fur is dirty, gently clean the surrounding area only if you’ve been advised that it’s appropriate for that wound.
Keep your dog from muddy ground, rough play, and anything that rubs the sore area. If the wound is on a leg or paw, short lead walks and a calmer routine may help reduce aggravation.
If the licking is constant, the wound is worsening, or you’re unsure whether it’s healing normally, it’s sensible to speak to your vet for tailored advice.
When To Contact A Vet
Contact your vet if the wound is getting more red, swollen, smelly, painful, or wet, or if your dog won’t leave it alone. You should also get advice if there’s discharge, the wound is opening up, or your dog seems unwell.
If the wound is near an eye, a joint, a paw pad, or it was caused by a bite, puncture, or foreign object, veterinary advice is especially sensible.
Products That May Help
For dogs with skin or wound-related care needs, gentle grooming and cleaning support can be useful as part of a sensible home routine while you monitor the area.
