Seeing a dog constantly licking and chewing its paws can be heartbreaking. At first, a little paw licking may seem harmless. Dogs sometimes lick their feet after walking outside, cleaning themselves or encountering something unusual.
But when the licking becomes frequent, intense or almost impossible for the dog to stop, it can be a sign that something is wrong. And when the paws become red, irritated or raw, the problem deserves attention. A dog shouldn’t have to spend its day fighting an itch or discomfort.
There are many possible reasons a dog may repeatedly lick its paws. Allergies are among the common possibilities. Dogs can react to environmental allergens such as pollen, grass, dust mites or mold. Some dogs can also develop reactions to ingredients in their food. Skin infections are another possibility.
Yeast and bacteria can thrive in warm, moist areas, particularly between a dog’s toes. Once irritation begins, a dog may lick the area repeatedly. Unfortunately, that licking can make the skin even more damaged. Itching leads to licking. Licking causes irritation. Irritation causes more itching.
Parasites can also cause intense itching. Fleas, mites and other external parasites may cause a dog to scratch or lick different parts of its body, including its feet. Then there are physical causes.
A small cut, splinter, thorn, cracked nail or piece of debris trapped between the toes can make a dog obsessively lick one particular paw. That’s why owners shouldn’t automatically assume that paw licking is caused by digestion.
Digestive problems can sometimes be associated with broader health issues, and some dogs with food sensitivities can experience both gastrointestinal and skin symptoms. But a raw paw by itself is not enough to prove that the dog’s digestive system is responsible. That distinction matters.
When a dog is clearly uncomfortable, the first priority should be finding the underlying cause. A veterinarian can examine the paws and skin, look for signs of infection or parasites and determine whether additional testing is necessary.
If the paws are already raw, bleeding, swollen or producing discharge, professional attention becomes even more important. The dog may be experiencing significant pain. Imagine having an itch that you cannot stop scratching. Now imagine that every time you scratch it, the skin becomes more irritated.
That’s essentially what can happen when a dog repeatedly licks an already damaged paw. Owners may sometimes try to stop the behavior by physically pulling the dog’s head away. But if the underlying problem remains, the dog will often return to licking as soon as the owner looks away.
That’s because the behavior isn’t necessarily a bad habit. The dog may be responding to genuine discomfort.
