Unlike in humans — where finger licking is a sign of having consumed a tasty meal — paw licking in dogs can be a health red flag. Though paw licking is a common behavior in pups, a history of excessive licking could be an indication of a more serious problem. While it's true they might simply be grooming themselves, paw chewing in particular could indicate something more going on if they are doing it all the time. It doesn't help that all that constant licking can also cause a secondary infection (bacterial or yeast) due to the extra moisture.

So, why do dogs lick in the first place?

An allergic reaction in the skin is the most common reason why dogs will chew their paws excessively. The good news here is that many of the causes of a dog's paw licking can be resolved with home treatment alone.

Common Causes For Paw Licking

Food Allergies

Food allergies occur when the immune system of your dog overreacts to some of the protein in the ingested food. An important note is that a food allergy differs from a food sensitivity in that allergies will cause an immediate immune reaction. The most common foods that cause allergies in dogs include beef, dairy, wheat egg and chicken. Dogs lick to relieve the itchiness caused by food allergies. Symptoms can include itchy rash, paw licking, hot spots, diarrhea and vomiting.

Environmental Allergies

For environmental allergies like atopic dermatitis, increased ear-scratching and foot-licking are common reactions to things like grass, mold spores, dust mites, and plant pollens. If you find your dog licking excessively more frequently after trips to the park or a walk around the block it's likely they have an environmental allergy. Symptoms can include increased sneezing, running eyes, paw licking, itchy skin and rashes.

Flea Allergies

When a dog’s immune system overreacts to flea saliva it's called flea allergy dermatitis (FAD). This allergic reaction causes an irritation in the skin which usually results in an extremely itchy sensation for the poor pup. Dogs will typically scratch and lick in an attempt to sooth the itch caused by flea allergies. Symptoms of FAD can include fur loss, thickened skin, redness, paw licking, and hot spots.

Dry Skin

Dry skin is one of the most common dog skin ailments which causes a dog's skin to become irritated, cracked and flaky (dandruff). Flaky skin can be caused by many things including excessive bathing, which removes a dog's natural oils, dry humidity, or by the allergies mentioned above. It's important to follow a good grooming schedule to ensure your dog's coat stays healthy. Symptoms of dry skin can include itchiness, fur loss, redness, dandruff and scabs.

Obsessive & Anxious Behavior

If no known health-related reason can be found for the excessive paw licking, then the cause could be behavioral. Dogs, like people, often seek ways to comfort themselves in times of stress. Is there a change in environment (noises, routine, new pets, or people) that might cause your dog to seek this form of stress relief? In addition to stress, some dogs have canine compulsive disorder which is a form of obsessive compulsive disorder, but in dogs. Common compulsive behaviors for dogs with CCD include paw licking, toy/blanket sucking, tail licking and tail chasing. Try to identify the causes of your dog's stressful and anxious behavior and use redirection and exercise to relieve it.


While any breeds can be overcome by boredom, it most typically affects working breeds including but are not limited to: German Shepherds, German Shorthaired Pointers, Golden Retrievers, Great Danes, Irish Setters, Labrador Retrievers, and Pointers. When boredom sets in, a dog may simply distract themselves by licking, for something to do.  

Potential Concerns: Lick Granuloma

A common cause for concern with excessive licking is called lick granuloma (also known as lick dermatitis), a stubborn skin disease. Lick granulomas are caused by repeated licking typically the lower leg leading to skin irritation. Lick granulomas differ from hot spots because they often persist despite treatment.

You know your dog better than anyone else so to help identify an abnormal situation, you must first know what is normal for your dog. Changes in health are often subtle, or happen over a longer period of time, making noticing a problem more difficult. 

As always, if you have any concerns whatsoever — especially if the paw chewing is sudden, excessive and persists for long periods of time — it is best to have your veterinarian assess your dog.
