Overview
If your dog keeps chewing a sore patch of skin, the area may be irritated, itchy, painful or already damp and inflamed. The first step is to stop the chewing if you can, then check the skin closely. A sore patch can have several causes, including a hot spot, bite irritation, allergies, parasites or a minor skin injury.
Things To Check
1. Check when the chewing starts, such as after exercise, grooming, time outdoors or resting.
2. Look for redness, swelling, broken skin, scabs, wetness, discharge or a bad smell.
3. Feel the area gently for heat, tenderness or thickened skin.
4. Check whether your dog is also licking, scratching or rubbing at other areas.
5. Look for fleas, ticks, burrs, grass seeds or other obvious irritants in the coat.
6. Note whether the patch is getting bigger, more painful or more moist over time.
Common Causes
The most common reason is a hot spot, which is a sore, irritated patch that can get worse quickly if your dog keeps licking or chewing it.
Other common causes include allergies, flea irritation, grooming irritation, insect bites, a small cut or abrasion, or something trapped in the coat such as a burr or grass seed.
Sometimes ongoing chewing is linked to discomfort elsewhere, such as sore ears, itchy paws or general skin sensitivity. Less commonly, a skin infection or another underlying health issue may be involved.
What To Do
Start by preventing more chewing so the skin has a chance to settle. If your dog will tolerate it, you can gently part the coat and inspect the area without rubbing it.
Keep the patch clean and dry, and avoid using human creams, sprays or antiseptics unless your vet has already told you to do so. If the coat is matted around the sore patch, it can trap moisture and make the irritation harder to settle, so careful grooming around the area may help.
It also helps to think about triggers. If the chewing tends to happen after walks, check for grass seeds, pollen, mud or debris. If it follows grooming, consider whether a product, clip or brush may have irritated the skin. If your dog is licking or chewing repeatedly, a collar or body covering may be useful as a short-term way to reduce damage while you monitor the skin.
When To Contact A Vet
Contact your vet if the area is spreading, very red, hot, smelly or oozing, or if your dog seems sore, unsettled or keeps reopening the patch. Veterinary advice is also sensible if the chewing keeps coming back, you can’t see an obvious cause, or the skin doesn’t start to improve with simple home care.
Products That May Help
For dogs with skin and coat irritation, pet care items can be useful as part of a gentle routine at home. They may help support regular cleaning, grooming and day-to-day skin care around a sore patch.
