If your dog occasionally licks their paws after a muddy walk, it may simply be part of normal grooming. When the behaviour is frequent, intense or focused on one paw, it is worth looking more closely.
There is no single explanation for persistent paw licking. Allergies, parasites, pain, infection and behavioural factors can all play a part, so avoid assuming that food must be responsible.
1. Something may be irritating their paws
Start with the paws themselves. Grass seeds, small stones, grit, salt, mud and other debris can become trapped around or between a dog’s toes.
Check each paw carefully, including:
- Between the toes
- Around the pads
- Around the nails
- Under longer fur
- For cuts or grazes
- For swelling or redness
If your dog suddenly concentrates intensely on one paw, a local injury or foreign object should be considered. Do not dig into the paw to remove anything deeply embedded; contact your vet.
2. Environmental allergies may cause itchy paws
Dogs encounter many substances during an ordinary walk. Depending on the individual dog, pollen, grasses, plants, dust mites and other environmental allergens may be associated with itchy or inflamed skin.
You may notice the licking becomes worse during a particular season or after visiting certain places. Record where your dog has walked, the time of year, grooming products used and when the licking becomes noticeably worse.
3. Food could be worth investigating
Food allergy can cause skin problems in dogs, including itchy feet, but food is only one possible explanation. Dogs may also experience adverse responses to foods that are not immune-mediated allergies.
If you suspect food is involved, review the whole diet rather than only the main meal:
- Treats
- Chews
- Table scraps
- Dental products
- Supplements
- Flavoured medications
Changing several foods at once makes patterns harder to identify. For persistent problems, speak to your vet about whether a properly controlled elimination-and-challenge diet is appropriate.
4. Fleas and other parasites can cause itching
Fleas, mites and other parasites can cause considerable irritation. Even if you have not seen fleas, do not automatically rule them out.
Check that your dog’s parasite prevention is appropriate and up to date, and speak to your vet if you are unsure which product or schedule is suitable.
5. Skin or yeast infections may make paws uncomfortable
Repeated licking adds moisture and can further damage already irritated skin. Bacteria or yeast may then contribute to a cycle of itching, licking and inflammation.
6. Pain can cause a dog to lick one area
Dogs sometimes repeatedly lick an area that hurts. A damaged nail, sore pad, joint problem or another source of limb pain may therefore appear to be a licking problem.
This is particularly important if the behaviour has appeared suddenly or is accompanied by limping, stiffness or reluctance to walk.
7. Behaviour can sometimes play a part
Some dogs lick when bored, stressed or unsettled, and repeated licking can become a habit. However, persistent licking should not automatically be dismissed as behavioural. Physical causes should be considered first, particularly if the skin is becoming sore.
How can I work out what is causing the licking?
Instead of changing everything at once, keep a simple diary for a couple of weeks.
What to record
Patterns can become much easier to spot when they are written down. Make one carefully considered change at a time unless your vet advises otherwise.
Could food intolerance be involved?
Food is one area owners may want to explore when recurring signs appear alongside digestive or general wellbeing concerns.
Pawspective offers an at-home Dog Intolerance Test using a small fur sample. Depending on the option selected, the personalised report covers 400 or 500 food, environmental, nutritional and metal items.
Pawspective testing is a complementary wellbeing tool. It does not diagnose allergies, food intolerance, disease or any other medical condition, and it cannot replace veterinary assessment or a veterinary elimination-and-challenge diet.
When should I contact a vet?
Contact your vet if your dog persistently licks or chews their paws, particularly if you notice:
- Broken or bleeding skin
- Significant redness or swelling
- Hair loss
- Discharge or unusual smell
- Limping or reluctance to walk
- Recurring ear or skin problems
- Vomiting or diarrhoea
- Significant discomfort
The bottom line
A dog that keeps licking their paws is showing that something may need attention. The reason might be straightforward irritation after a walk, but persistent licking can have many possible causes, including parasites, skin problems, allergies, pain and dietary factors.
Look at the complete picture rather than assuming one cause. Careful observation and timely veterinary advice are the most reliable next steps.
