If your westie is licking or chewing their paws persistently – especially at night when everything is quiet – that’s not a quirk or a bad habit. It’s the earliest and most reliable sign of an allergy flare-up.
This was exactly how Sami’s allergies started. Around one year old, he began licking and biting his paws after running in the grass. I thought it was cute at first. It wasn’t. The skin between his toes is one of the thinnest spots on his body and it reacts first to allergens. That persistent nighttime licking was always the signal that something was happening with his skin.
Why the Paws
Westie paws are ground zero for allergen exposure. Every walk, your dog’s paws contact grass, pollen, dust, and whatever’s on the ground. These allergens get trapped between the toes, where the skin is thin and sensitive. The warm, slightly moist environment between the toes is also ideal for yeast growth.
In westies specifically, the paws are one of the three areas that react first to atopic dermatitis (the others are behind the ears and around the muzzle). International studies of allergic dogs show that both front and back feet are among the most severely affected areas in westies.
How to Tell Allergies From Boredom
Boredom licking tends to be casual and intermittent. Your westie might lick a paw for a moment and then move on. Allergy-driven licking is persistent, focused, and often intense. The dog returns to the same spot repeatedly, sometimes for minutes at a time. They may lick until the fur between the toes turns a reddish-brown color (saliva staining), or until the skin is visibly pink and raw.
Nighttime licking is almost always allergy-related. A bored dog licks during the day when there’s nothing else to do. An allergic dog licks at night because the itching doesn’t stop when the lights go off.
The Licking Cycle and Why It Gets Worse
Licking creates a self-reinforcing cycle. Allergens irritate the skin, the dog licks for relief, the saliva introduces bacteria and moisture, the bacteria cause infection, the infection makes the itching worse, the dog licks more. Left unchecked, a mild itch becomes red, raw, infected skin within days.
Breaking the cycle means addressing both the symptom (the licking) and the cause (the allergens).
How to Stop the Paw Licking
Daily paw wipe-down. After every walk, wipe all four paws with fragrance-free grooming wipes. Get between every toe. This removes allergens before they can trigger the itch-lick cycle. I do this with Sami every evening as part of our routine.
Cone at night during active licking periods. A recovery cone prevents overnight licking, which is when the most damage happens. After 2-3 nights in a cone, the skin gets a chance to heal without constant re-irritation from saliva.
Chlorhexidine on affected paws. If the skin between the toes is already pink or irritated, clean it with chlorhexidine wipes (2-3% concentration). This kills bacteria and yeast without adding moisture.
Paw soaks for severe cases. During bad periods, a lukewarm paw soak in diluted chlorhexidine solution can help. Let the paws soak for 2-5 minutes, then dry completely. The key word is completely – damp paws make everything worse.
Address the underlying allergy. Paw licking is a symptom. The cause is the allergy triggering it. Environmental controls, bathing frequency, diet, and potentially vet-prescribed medication all factor into the bigger solution. See our complete skin and allergies guide for the full protocol.
The Saliva Staining Problem
Persistent licking turns white westie fur reddish-brown. This is saliva staining – the iron in dog saliva oxidizes and discolors the fur. It’s not harmful in itself, but it’s a visible indicator that your westie has been licking excessively.
The staining itself doesn’t need treatment. Once you resolve the licking, the discolored fur grows out and is replaced by white fur. Trying to bleach or clean the staining while the licking continues is treating the cosmetic symptom, not the problem.
When Paw Licking Needs a Vet
If daily wipe-downs and a cone aren’t reducing the licking within a week. If you see swelling, open sores, or discharge between the toes. If the paws have a strong yeasty smell that doesn’t improve with chlorhexidine. If the licking is so persistent it’s disrupting your westie’s sleep or appetite. Any of these warrant a vet visit for proper allergy assessment and potentially prescription medication.
