Why does my dog lick his paws?

4 min read Updated on October 8, 2026

In shortA little licking after a walk or before bed is just grooming. Long, repeated licking that reddens the skin or turns the fur rust-colored usually signals a problem: itching from an allergy, a foxtail or a cut between the toes, parasites, an infection, or pain. Boredom and stress exist too, but they only count once physical causes are ruled out. First clue: check whether he licks one paw or all four.

What it often means

Normal grooming: a few minutes after a walk, after a meal or before a nap, with no redness or smell, is just upkeep.
An allergy: 2015 veterinary guidelines describe itchy paws, ears and belly as typical signs of atopic dermatitis, a common allergy in dogs.
A local problem: a foxtail lodged between the toes, a cut, a pad burned by hot asphalt or cracked by ice melt, a broken nail, or chiggers in summer and fall.
Pain: a 2020 review points out that pain often hides behind behaviors like licking. An arthritic toe or wrist can be licked endlessly.
More rarely, boredom or anxiety: licking soothes, then irritates the skin, which itches, which restarts the licking. It is a cycle to break.

Signals to read at the same time

One paw or all four: a single paw points to an injury, a foreign body or pain; all four point more to an allergy.
Other areas: does he also scratch his ears, belly or armpits, rub his face on the rug, or scoot his butt on the floor?
Skin and fur: redness, swelling between the toes, a yeasty smell, fur turned rust-colored from saliva on a light-colored dog.
Timing and season: in the quiet of the evening, after tall grass, in spring, in late summer, or in winter after salted sidewalks.
His gait: limping, a raised paw, stiffness when he gets up, hesitation on hard floors, all of which point to pain.

What you can do

Check the paw in good light: spread the toes, look between the pads and around the nails for a foxtail, a cut or tiny orange dots.
After walks, rinse his paws with plain water and dry well between the toes, especially in winter and after treated lawns.
Do not apply human creams or essential oils: he would lick them off, and some are toxic to him.
For a week, note when and for how long he licks, and film an episode: it will help your vet see clearly.
If boredom plays a part, add a sniffing walk and something to chew every day, and interrupt the licking by offering an activity, not by scolding.

When to see a vet

See a vet if the licking lasts more than a few days, comes back every season or wakes him at night, if he licks a single paw while limping or with swelling between the toes, if the skin is red, oozing or smelly, or if he also scratches his ears and belly. Allergies, infections, parasites, a foreign body or joint pain are the usual causes. A foxtail can burrow under the skin and travel: have it removed without waiting.

Frequently asked questions

My dog licks his paws every night. Is that normal?

A few minutes of grooming before sleep, yes. If it goes on and on, always targets the same spot, reddens the skin or wakes him at night, it is itching, not a ritual. The evening calm simply makes it easier to notice.

Why is the fur between his toes turning reddish-brown?

Pigments in saliva stain light fur when he licks the same spot often. It is not serious in itself, but it proves frequent licking, and sometimes a yeast infection. Show it to your vet.

Could he be allergic to his food?

It is possible: a food allergy can also cause paw licking and ear scratching. But switching brands at random will not tell you. The only way to know is a strict elimination diet lasting several weeks, chosen with your vet, with no other treats at all.

Can paw licking come from stress?

Yes: licking can soothe a bored or worried dog and become compulsive, like tail chasing. But it is rarely the first cause: rule out allergies, parasites and pain first. If it has become compulsive, your vet can refer you to a veterinary behaviorist. Endless licking can leave a stubborn sore on the front of the leg.
