A dog stopping mid-day to give its paws a few quick licks is usually nothing to worry about. Like people, dogs groom themselves, and occasional paw licking can simply be part of that routine. But when the licking becomes frequent, intense or almost impossible to interrupt, it can be your dog’s way of saying that something is wrong. Veterinary experts say persistent paw licking is commonly linked to itching, allergies, irritation, injury or infection. In some cases, it can also have a behavioural cause. Scroll down to know more.
Allergies are a common culprit
If your dog is repeatedly licking several paws, allergies are one of the first possibilities to consider. Dogs can develop environmental allergies to substances such as pollen, grass, weeds, mould and dust mites. Food allergies can also cause itchy skin and chronic paw licking. Flea allergies are another possibility. The paws and the skin between the toes are particularly common places for allergic irritation to show up. Depending on the trigger, symptoms may come and go seasonally or persist throughout the year.
Something may be irritating the paws
Sometimes the explanation is much closer to the ground. Grass, dirt, chemicals, cleaning products or other substances a dog encounters while walking can irritate its paws. Hot surfaces can also cause burns or discomfort, while a small thorn, splinter, stone or grass seed can become lodged between the toes. If the licking suddenly starts and is concentrated on one paw, carefully checking the pads, nails and spaces between the toes is particularly important.
An injury or pain could be behind it
Dogs may lick an area that hurts. A cut, torn nail, insect sting, blister or other injury can prompt repeated licking. Interestingly, the source of discomfort is not always the paw itself. Dogs experiencing pain elsewhere in a limb or body may sometimes lick a particular paw as a coping behaviour. Persistent or sudden licking therefore deserves attention rather than being dismissed as simple grooming.
Watch for bacterial or yeast infections
Constant licking can create a vicious cycle. Moisture and repeated irritation can damage the skin barrier, allowing bacteria or yeast to multiply. The resulting infection makes the paw itchier, which encourages even more licking. Look for redness, swelling, hair loss, brown or pink staining around the toes, an unusual smell, discharge, crusting or thickened skin. These signs can point towards inflammation or infection and warrant veterinary attention.
Parasites can make paws unbearably itchy
Fleas and other parasites can trigger intense itching. A dog may respond by licking, chewing or scratching its paws and other parts of its body. Regular parasite prevention is therefore an important part of managing recurring itching, but persistent symptoms should still be assessed by a veterinarian to establish the actual cause.
Sometimes, it is behavioural
Not every case of excessive licking has a physical cause. Boredom, anxiety or compulsive behaviour can also lead some dogs to repeatedly lick themselves. However, behavioural explanations should generally be considered after medical causes have been investigated. A dog that suddenly develops obsessive paw licking may be dealing with pain, allergies or another condition rather than simply seeking attention.
When should pet parents worry?
Occasional licking is generally normal. But it is time to pay closer attention if your dog is licking its paws repeatedly or chewing them, particularly if you notice red or swollen skin, wounds, bleeding, discharge, an unusual odour, limping, hair loss or obvious pain. Instead of simply trying to stop the licking, the important thing is to find out why it is happening. Treating the underlying problem can stop the cycle before constant licking causes further skin damage or infection.
