Why Do Dogs Lick Their Paws?

2. Allergies

Another common reason dogs lick their paws is a subtle allergic reaction. This often manifests as itchy feet, which causes dogs to lick and chew excessively in an effort to soothe the itch. This is most commonly seen with environmental or food allergies, so if your dog starts licking his paws suddenly after you change foods or start using a new grooming product, this may be a cause. If there isn't an obvious new allergen, call your vet to schedule an appointment.
