Quick answer: Dogs chew or nibble their feet and nails mainly because of itching (often allergies or fleas), overgrown or broken nails, something stuck in the paw, dry skin or boredom and anxiety. Occasional nibbling is normal. Frequent or intense chewing deserves a closer look.
You may hear it before you see it: that little ‘nibble nibble’ sound as your dog chews at their toes. Some dogs do it briefly as part of grooming. Others seem almost obsessed.
Chewing is a step beyond licking. Teeth can break the skin, which opens the door to infection, so it’s worth figuring out the cause.
Why Dogs Chew Their Feet
- Itchy skin. Allergies (environmental or food) and fleas are the most common causes of itchy feet.
- Long nails. Overgrown nails can be uncomfortable and change how a dog stands. Some dogs chew at them.
- Broken or split nails, which can be painful.
- Foreign objects like burrs, splinters or grass seeds between the toes.
- Dry, cracked pads, especially in winter.
- Skin or nail bed infections, often with swelling, redness or discharge.
- Boredom, stress or anxiety, sometimes becoming a compulsive habit.
Licking vs. Chewing
| Behavior | Often means |
|---|---|
| Brief licking after walks | Normal cleaning |
| Frequent licking | Allergies or irritation |
| Nibbling between toes | Itch, debris or infection |
| Chewing nails | Overgrown or broken nails, or itchy nail beds |
| Chewing until skin is raw | Needs a vet visit |
How to Help
- Inspect the paws between toes and around nails for redness, swelling, debris or broken nails.
- Trim nails regularly. If you hear clicking on hard floors, they’re probably too long. Your groomer or vet can help if you’re unsure.
- Keep up with flea prevention.
- Clean and dry paws after walks.
- Moisturize pads with a dog-safe paw balm in dry or cold weather.
- Add exercise and chew toys for dogs who chew out of boredom.
- Use a cone or booties to protect raw spots while they heal, if your vet recommends it.
When to See the Vet
- Broken skin, bleeding, swelling or pus
- Limping or not wanting to put weight on a foot
- A torn or broken nail (these can be very painful)
- Chewing that lasts more than a few days
- Hair loss or a bad smell from the paws
- Itching in other areas, like ears, belly or rear
