Why a dog repeatedly licks the same paw: what it may mean

In France, a dog that repeatedly licks the same paw is not necessarily grooming itself: this behaviour may indicate genuine discomfort.

Published on 27 June 2025, the source article points out that dogs also communicate through their behaviour. When an animal persistently focuses on one paw, its owner should monitor how often it does so, inspect the skin and note any changes from its usual behaviour.

Repeated paw licking needs attention

A dog may lick its paws after a walk to remove dust, or simply as part of its grooming routine. However, the behaviour becomes more concerning when it is persistent, happens every day or is limited to one particular area.

The recurring sound of licking may initially seem harmless. However, it can point to irritation, pain or stress. In some cases, repeated nibbling and licking can cause the dog to create a wound itself. The affected area may then become red, swollen, lose fur or develop an unusual smell.

“Frequent, obsessive licking is not a whim: it may be the visible sign of a medical or behavioural problem.”

Veterinarian Carmen Arteaga has warned on social media that overlooking this behaviour may allow the issue to worsen. A consultation can establish whether the dog has a physical source of discomfort or a problem associated with stress or boredom.

Medical causes to rule out first

Before treating this action as a habit, the first priority is to identify any physical cause. Allergies are among the most common explanations. They may be triggered by the environment, including pollen or dust mites, or by food.

The Merck Veterinary Manual, cited in the source article, states that atopic dermatitis affects around 10 to 15% of dogs. This condition is an allergic reaction that causes itching. As paws are often exposed to irritants outdoors, they may become a particular focus for licking.

Other circumstances may also account for this reaction:

• fleas, ticks or other parasites;
• a bacterial or fungal infection;
• a thorn, small piece of debris or insect bite between the toes;
• a cut or irritation caused by the ground;
• localised pain, including joint pain.

A dog with arthritis may likewise lick a painful paw or joint. This behaviour cannot provide a diagnosis from a distance. Instead, it is a clue to report to the veterinarian, together with details about how long it has lasted, how often it occurs and the circumstances in which it appears.

Signs that should prompt a veterinary appointment

Some symptoms should encourage an owner to book an appointment without delaying for too long. These include a paw that looks hot, red or swollen, or a dog that is limping. Fur loss, scabs, bleeding or discharge should also be reported.

The veterinarian may inspect the skin and paw pads, check for parasites, take a skin sample or recommend further tests depending on the circumstances. An elimination diet may also be considered if a food allergy is suspected.

Boredom and anxiety may also be involved

Once medical causes have been ruled out, licking may be connected to the animal’s psychological wellbeing. Dr Karen Overall, a veterinary behavioural medicine specialist quoted in the article, has studied compulsive behaviours in dogs. These repetitive actions can be an attempt at self-soothing.

The mechanism is similar to certain human behaviours, such as biting one’s nails during a stressful period. In dogs, separation anxiety can encourage this type of response. A change of surroundings, moving home or the arrival of a new household member can also unsettle the dog’s familiar routine.

Boredom is another possibility. A dog that does not have suitable walks, games or scent-based activities may repeat a behaviour to occupy itself. This does not mean that every dog that licks its paws is bored. It is a possibility to explore after a veterinary assessment.

“A paw that is medically healthy is not always enough to stop the licking: the dog’s environment and daily routine matter too.”

In France, the veterinarian remains the key point of contact

In France, the veterinarian is the qualified professional to assess the physical causes of excessive licking. If the issue appears to stem from anxiety or compulsive behaviour, they can then refer the owner to a veterinarian who practises behavioural medicine.

While waiting for the appointment, it is best not to apply a human product to the paw without professional advice. Some creams, oils or disinfectants may cause irritation or be dangerous if the animal swallows them while licking. Keeping the paw clean and dry may help limit the risk of the condition worsening, but it is not a substitute for a clinical examination.

Useful everyday adjustments

If the veterinarian identifies a behavioural cause, straightforward changes may help reduce periods of stress. The aim is not merely to tire the dog out, but to offer activities suited to its needs.

• Vary walks, allowing the dog time to sniff its surroundings.
• Plan regular, calm play sessions.
• Use enrichment toys, snuffle mats or food puzzles.
• Avoid punishing the dog for licking, as this response can increase its stress.
• Record when the behaviour occurs to identify a possible trigger.

Food-search activities make particular use of the dog’s sense of smell, which is a major sense for the animal. They can keep it occupied for a while and direct its attention elsewhere. They do not replace walks or veterinary care, but may complement a more balanced routine.

When licking has been established for a long time or causes lesions, behavioural support may be needed. The goal is then to address the cause, protect the skin and prevent the action from becoming a habit that is difficult to stop.
