Dogs chewing on their own paws may be caused by interdigital inflammation, allergies, boredom, etc. If dogs live in a humid environment for a long time, their paws will breed a lot of bacteria and parasites, causing infections. They must be disinfected in time, and then take the dog to a pet hospital for examination and treatment. Dogs will also chew their own paws when they are bored. Owners can buy some toys to help divert the dog's attention.
