I have a german shepherd female she is about 11 months old. She kept licking and biting at her tail and when I inspected it looks to be a swolln red bump on it. Like a swollen pimple or a ingrown hair that is infected. It is about 8 inches from the tip of the tail. Look at picture. Should I take her to the vet or will this be sonething that heals on its own?
