Overview
If your dog suddenly starts biting at a paw, the first things to check are the paw pads, between the toes and the nails for something stuck, a small cut, redness or a grass seed. A dog may do this because of a minor irritant, but there can be several possible causes, so it’s worth looking closely rather than assuming it will settle on its own.
Things To Check
1. Check whether it started after a walk, turnout, grooming or exercise, as that can point to something picked up outdoors.
2. Look closely between the toes and around the pads for grass seeds, dirt, small stones, twigs or any other visible debris.
3. Check for redness, swelling, heat, broken skin, a scab, dampness or any discharge.
4. Gently look at the nails, nail beds and claws for cracking, lifting, splitting or signs of soreness.
5. Notice whether your dog is licking, chewing or biting one paw only, or several paws, as that can help you narrow down whether it’s local irritation or something more general.
6. Check for signs of discomfort when the paw is touched, such as pulling away, limping or not wanting to put weight on it.
7. If your dog has long hair around the feet, check whether it’s matting, trapping moisture or hiding something stuck in the fur.
8. Think about any recent changes in grass, woodland walks or hedge-side exercise, where seed heads and burrs can be more of an issue.
Common Causes
The most common reason is a small irritant such as a grass seed, burr, stone or bit of debris caught in the fur or between the toes. Minor cuts, cracked pads or a sore nail can also make a dog bite at the area.
Less commonly, the problem may be linked to skin irritation, an insect bite, allergy-related itching or a small infection starting in the paw. In some cases, a grass seed can work its way into the skin and cause ongoing irritation, which is why a close check matters.
What To Do
If your dog will tolerate it, examine the paw in good light and part the fur carefully so you can see the pads and spaces between the toes. If you find loose debris, remove only what is easy and obvious. If something looks embedded, don’t dig at it.
Rinse the paw gently with clean lukewarm water if it’s dirty, then dry it well, especially between the toes. Keep an eye on whether the biting settles once the paw is clean and dry, and try to prevent more licking or biting if the area looks sore.
It also helps to monitor for any change over the next day or so. If the paw gets more swollen, starts to ooze, smells unpleasant, or your dog becomes lame or keeps worrying the same spot, it’s sensible to ask your vet for advice.
