Paw licking is often overlooked by owners as they assume their dog is grooming or that it’s just one of their quirks, and because the frequency of licking gradually increases over time, it’s easy for owners to miss the change in behaviour.

To help out Dr Tanya Leslie, Veterinary Advisor for DOUXO, has shared how to distinguish between a behavioural habit and a yeast problem, alongside tips for managing paw irritation this autumn.

Here’s what she had to say.

Why wet walks can cause irritation

During autumn and winter, dogs’ paws frequently come into contact with rainwater and mud. While many owners think they are properly towel-drying their dog, it’s easy to leave some water behind, as it can be difficult to get in between the toes, especially if your dog is a bit ticklish around their feet. The moisture and dirt picked up on walks can remain trapped in the paws, causing irritation and potentially resulting in an overgrowth of yeast.

This can be extremely itchy for dogs, causing them to lick the area and add even more moisture and bacteria to the skin, leading to a cycle of irritation.

How to tell when paw licking is more than a habit

If your dog displays any of these symptoms alongside persistent licking of one or more paws, it could signal irritation or an infection:

• Guarding a paw more than usual when you try to touch it
• Red, inflamed or itchy skin patches appearing through the fur
• Swellings between the toes or sticky discharge
• Crusty or flaky skin, sometimes with patches of hair loss
• Dark or black spots on the skin
• Reddish, brown discolouration at the site of licking
• A strong, unpleasant odour coming from affected skin

Owners should pay attention to when the licking occurs and how long it lasts for. If a dog starts licking constantly and immediately returns to the licking after you’ve distracted them with food or a toy, it might mean that they are struggling with a skin allergy or a yeast overgrowth (or both!).

Three things to do after a wet walk

Clean the paws

Use good quality wipes to clean your dog’s paws after a walk, or if they tolerate it, rinse your dog's paws and lower legs under running water. Try to focus on rinsing the areas between the pads and toes if possible. If your dog has been diagnosed with a yeast overgrowth by their vet, you have been recommended a product with a topical antiseptic in it. If possible, apply this once the worst of the debris has been rinsed away, and follow the instructions about massaging in or rinsing out.

Dry between the toes

Gently but thoroughly dry between each toe and around the pads, where moisture is likely to get trapped. For dogs with a lot of fur between their paw pads, owners can ask their groomer to trim any excess fur to help improve airflow and make for easier cleaning and drying.

Check the skin

Routinely checking your dog’s paws after walks can help to spot changes sooner. Look out for the symptoms of infection or irritation.

When to go to the vet

Persistent licking shouldn’t be ignored, especially if it begins to damage the skin. If the licking causes sores, bleeding or hair loss, take them to the vet, as your dog may need treatment to relieve the discomfort and address the cause.
