why do dogs lick themselves

Dogs lick themselves primarily for grooming to keep their fur clean by removing dirt and debris. Licking also acts as self-soothing behavior to relieve itchiness caused by allergies, parasites like fleas, or skin infections. Additionally, dogs may lick an area that is painful or uncomfortable to provide temporary relief. Excessive licking can be a sign of medical issues such as allergies, pain, or stress and may require veterinary attention. Dogs also lick to communicate, seek attention, or because of compulsive behaviors related to anxiety. Overall, licking serves multiple natural functions such as hygiene, comfort, and communication for dogs.
