Why is my dog biting her tail and itching despite flea treatment?
Poor Cali is having a rough time lately! In my experience, flea shampoos, collars, and dips do not work to prevent fleas, nor do they kill them very well. I can give you a flea treatment program that can help with fleas. You did the right thing, however, by bug bombing the house and flea spraying the yard. As for treating the fleas, first I would give Cali 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.
Other causes of the itching of her tail include mites, ringworm, or allergies. You can take Cali into the vet to rule out these causes of her biting her tail. 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.
