Why does my dog keep chewing the same paw?

Overview
If your dog keeps chewing the same paw, it often means that paw is irritating them in some way. A small foreign body, a bit of debris, a minor skin sore, an insect bite, or general itchiness can all make a dog focus on one foot. It’s sensible to check the paw carefully, but you usually can’t confirm the exact cause at home.
Things To Check
1. See whether the chewing happens after walks, grass time, muddy outings, grooming, or exercise.
2. Look closely between the toes and around the pads for grass seeds, thorns, gravel, splinters, burrs, or other debris.
3. Check for redness, swelling, broken skin, scabs, dampness, or anything that looks sore.
4. Feel the paw gently for heat or tenderness compared with the other paws.
5. Notice whether your dog is limping, licking more than chewing, or avoiding putting weight on that foot.
6. Smell the paw for an unusual odour, which can sometimes go along with skin irritation or infection.
7. Check the nails and nail beds, since a broken nail or nail-bed irritation can also draw attention to one paw.
Common Causes
The most common reason is something irritating the paw, such as a grass seed, tiny stone, burr or bit of grit caught in the fur or between the pads. Dogs also often chew one paw if there’s a small cut, a cracked pad, or soreness from walking on rough ground.
Another common cause is skin irritation, which may happen after contact with wet ground, grooming products, pollen or other everyday allergens. Sometimes a dog keeps chewing one paw because they’ve been licking it for a while and the skin has become more inflamed.
Less commonly, a broken nail, nail-bed problem, insect sting or an early skin infection can be behind the chewing. If the paw keeps worsening or the problem keeps coming back, there may be an underlying issue that needs a vet to take a proper look.
What To Do
Start by gently cleaning the paw with lukewarm water and checking it in good light. If you can see loose debris sitting on the surface, remove it carefully, but don’t dig around if something looks embedded or painful.
Dry the paw well afterwards, especially between the toes. Try to keep your dog from chewing it more, because repeated licking and chewing can make the skin sore very quickly.
For the next day or two, keep an eye on whether the chewing settles or whether the paw becomes redder, swollen or more sensitive. If the issue keeps happening, note when it started and what your dog had been doing beforehand, as that can help a vet work out the likely cause.
When To Contact A Vet
Contact your vet if you suspect something is embedded in the paw, if there’s swelling, pus, bleeding, a broken nail, or your dog is limping or clearly uncomfortable. You should also get advice if the chewing keeps going for more than a day or two, or if the paw looks worse rather than better.
Products That May Help
If your dog often ends up with muddy paws, trapped debris or general paw mess after walks, routine pet care products can be useful for keeping their feet clean and easy to check.
