Dog biting tail and has bumps. Is it fleas, worms, or allergies?

Question

Dottie has been biting her butt on top of her tail and has some bumps. Could it be worms that we could treat at home? Or would we need something from the vet? Could her first heat have anything to do with it? Pet's info: Dog | American Pit Bull Terrier | Female | 9 months and 6 days old | 60 lbs

This biting could be caused by fleas, mites, ringworm, or allergies. If Dottie isn't up to date on her flea treatment, I can give you one for her. First, I would give her Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash her bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. If she is up to date on her flea treatment, I recommend taking her into the vet for an exam tomorrow. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can prescribe the appropriate treatment. Best of luck.
