Why Is My Dog Licking Their Paws So Much?

When to call your vet

Book an appointment, or ring for advice the same day, if your dog:

• Is limping, holding a foot up, or won't put weight on it
• Has a swollen paw, or a lump between the toes that is red, hot or oozing
• Has a cut, torn nail or pad injury that is bleeding or looks deep
• Starts licking one paw suddenly and intensely after a walk, especially in summer when grass seeds are about
• Has red, brown-stained, smelly or greasy skin between the toes
• Has broken skin or sore patches from licking
• Has been licking for more than a few days without an obvious cause
• May have walked through something harmful, such as antifreeze, chemicals or road de-icer

A bleeding wound that won't stop with gentle pressure, or a dog who seems in a lot of pain, should be seen urgently.

Normal grooming or a problem?

Dogs clean their feet, especially after muddy walks or meals, and some lick their paws briefly as they settle down to sleep. This sort of licking is short, gentle and doesn't leave marks.

Licking becomes a concern when it is:

• Frequent enough that you notice it most days
• Hard to interrupt, or wakes your dog at night
• Focused on one paw rather than all four
• Leaving the fur stained reddish-brown (saliva can discolour pale fur)
• Paired with chewing, nibbling or biting at the toes

Common reasons dogs lick their paws

Pattern you might notice	Possible causes to discuss with your vet
Several paws, on and off for weeks, often with itchy ears or tummy	Environmental or food allergies, skin infection
One paw, started suddenly	Grass seed, splinter, cut, torn nail, insect sting
One paw with a lump between the toes	Interdigital cyst or infection, embedded foreign body
Licking mostly when left alone or bored	Anxiety, frustration, lack of stimulation
Licking one leg or wrist in an older dog	Joint pain or arthritis
Licking after winter walks	Irritation from grit, salt or de-icer, cracked pads

Allergies and itchy skin

Allergies are one of the most common reasons for long-term paw licking. Dogs can react to things in their environment, such as pollens, dust mites and moulds, or less commonly to ingredients in their food. Itchy paws often go hand in hand with itchy ears, face, armpits or tummy. Constant licking keeps the skin moist, and yeast or bacterial infections can then take hold, which makes the itch worse.

Working out the cause of an allergy can take time, and your vet may suggest tests, a food trial or treatment for any infection. Our article on why dogs scratch so much covers itchy skin in more detail.

Injuries and things stuck in the paw

Sudden licking of one paw is often a sign that something hurts. Grass awns are a well-known culprit in summer: their pointed shape lets them work their way into the skin between the toes, where they can cause painful swellings. Thorns, glass, stings, burns from hot pavements and torn nails can also trigger licking. If your dog is also limping, see our guide to dog limping.

Pain elsewhere

Dogs sometimes lick over a sore joint. An older dog who repeatedly licks a wrist or ankle may be uncomfortable there, and our page on arthritis in dogs explains other signs to look out for.

Boredom and anxiety

Licking can be soothing. Some dogs lick when anxious, when left alone, or when they don't get enough exercise and mental stimulation. This can become a habit that persists even after the original trigger is gone. If you suspect stress, our guide to separation anxiety may help.

How to check your dog's paws

Do this in good light, gently, and stop if your dog is in pain or becomes worried.

1. Look at the whole foot. Compare it with the other feet. Is it swollen, red or warmer?
2. Spread the toes. Check between them for seeds, burrs, stones or redness. Long-haired dogs can hide a lot in their foot fur.
3. Check the pads. Look for cuts, cracks, blisters or anything embedded.
4. Check the nails. Look for any that are split, torn or overgrown.
5. Sniff. A yeasty or unpleasant smell can point to infection.
6. Note when it happens. After walks, at night, when alone, or all the time?

Don't try to dig out anything embedded deep in the skin, and don't squeeze lumps. Grass seeds in particular can break up or be pushed further in. Leave this to your vet.

Everyday care that helps

• Rinse and dry paws after walks, particularly after muddy fields or gritted pavements in winter. Pay attention to drying between the toes. Our cold weather care guide has more on winter paws.
• Keep foot fur trimmed in breeds that grow long hair between the pads, to reduce trapped seeds and matting.
• Avoid hot pavements on summer days. If it is too hot for the back of your hand, it is too hot for paws.
• Keep up with flea treatment, as fleas can make the whole body itchy.
• Give plenty to do. Walks with time to sniff, puzzle feeders and training games can reduce boredom licking.
• Don't use human creams or medicines on your dog's paws unless your vet has advised them. Dogs often lick off whatever is applied, and some products are harmful if swallowed.

If your vet suggests a cone or a protective boot to break the licking cycle while skin heals, follow their guidance on how long to use it.

Spotting patterns over time

Paw licking that comes and goes can be hard to describe accurately at an appointment. Is it worse in spring? After a food change? On days your dog is home alone? Making a quick note each day, along with meals, walks and any new products, often reveals a pattern that is easy to miss otherwise. Petopedia lets you record food, water, weight and behaviour together, so you can show your vet a clear timeline rather than relying on memory.
