Dogs chew their paws for several reasons, most commonly due to pain, irritation, or discomfort. Some typical causes include allergies (to food, environmental factors, or fleas), injuries (cuts, torn nails, stings, or foreign objects), skin infections (bacterial or yeast), grooming issues (overgrown or torn nails, mats between toes), anxiety or stress, and even behavioral compulsions. Here are key points why a dog might chew its paws:

• Allergies: Dogs often chew their paws because of allergies, which cause itching, redness, and inflammation. These can be environmental (pollen, grass, mold), food-related, or due to flea bites.
• Injuries and pain: Physical pain from cuts, stings, burns, fractures, or arthritis can lead to paw chewing.
• Skin infections: Secondary bacterial or yeast infections due to inflammation may develop if the paw is irritated.
• Grooming issues: Problems like overgrown nails or tangled fur can cause discomfort and chewing.
• Anxiety and boredom: Paw chewing can also be a coping mechanism for stress, anxiety, or boredom in dogs.

If the chewing is excessive, causing injury, or accompanied by other symptoms like limping or swelling, it is best to consult a veterinarian to determine the underlying cause and get appropriate treatment.
