Why do dogs lick their paws
Why do dogs lick their paws? Discover the top medical and behavioral causes, from allergies and joint pain to boredom, and when to see a vet.
Most dogs lick their paws due to allergies, pain, or boredom, but the specific cause depends entirely on whether the dog is a breed like the Newfoundland, which is genetically predisposed to skin conditions and joint issues. While occasional grooming is normal, persistent licking often signals a medical problem that requires a vet to diagnose.
Allergies and skin conditions drive the behavior
Atopic dermatitis and food allergies are among the most common reasons for excessive paw licking. In breeds like the Newfoundland, the risk is compounded by a genetic predisposition to allergic skin disease, ichthyosis, and primary seborrhoea. These conditions cause intense itching, and because the paws are easily accessible, the dog licks to soothe the irritation. This behavior can quickly escalate into acral lick dermatitis, a self-inflicted wound that becomes a cycle of inflammation and infection.
Pain and joint issues are a frequent trigger
Dogs often lick a specific paw to mask or soothe localized pain, particularly in large breeds prone to orthopedic issues. Newfoundlands have the highest prevalence of canine hip dysplasia (17.16%) and cranial cruciate ligament deficiency (CCLD) of any breed, with 8.9% affected. Even if the dog does not limp visibly, discomfort in the hips, knees, or elbows can manifest as licking at the paws. A dog with arthritis or a subtle injury may lick the area to distract from the ache, making the behavior a sign of physical distress rather than a habit.
Boredom and anxiety play a significant role
When medical causes are ruled out, the behavior often stems from a lack of mental stimulation or stress. Large working breeds like the Newfoundland were bred to pull fishnets and haul carts; without a job or sufficient activity, they can develop compulsive behaviors. The repetitive motion of licking releases endorphins that calm the dog, similar to how humans might fidget. This is particularly common in dogs that are left alone for long periods or lack the cognitive engagement they require.
When to seek veterinary care
Owners should monitor the frequency and intensity of the licking. If the paws are red, swollen, or if the dog is limping, a veterinary visit is necessary to rule out infection, foreign bodies like grass seeds, or underlying joint disease. In Newfoundlands, the risk of gastric dilation volvulus (GDV) is also significantly higher (10% of deaths in some surveys) compared to the general population, and while not directly linked to licking, the breed's overall health profile requires vigilant monitoring. A dog that licks until the skin is raw or bleeds needs professional intervention to break the cycle and treat the root cause.
Understanding the specific breed predispositions, such as the Newfoundland's high rates of hip dysplasia and skin conditions, helps distinguish between a simple itch and a serious health issue. Addressing the underlying cause, whether it is an allergy, a joint problem, or a behavioral need, is the only way to stop the cycle effectively.
