Q: Why does my dog lick his paws?

A: Paw licking is one of the most common canine habits, and one of the easiest to misinterpret. Occasional licking is perfectly normal; it’s how dogs groom and soothe themselves. But when it becomes excessive, persistent, or focused on one paw, it’s a sign that something’s not right.

The causes range from allergies (to grass, pollen, food, or dust mites) to skin infections, foreign bodies like grass seeds, or even joint pain. Chronic licking can create what’s known as a lick granuloma, which is a sore spot that becomes self-perpetuating because the act of licking releases endorphins, giving temporary relief while worsening the irritation.

If your dog is licking daily, check for redness, swelling, or smell between the toes, and talk to your vet. Identifying the underlying trigger, whether it’s environmental, dietary, or pain-related, is key. As with most things, you don’t just need to treat the symptom but rather find the source.
