Q. Our dog has a skin infection on abd. And back legs. Keflex did not help. No fleas found; can we try a topical flea product while skin is infected?

Answered By

A. You can use a spot on flea treatment such as advocate or advantage, even if the skin is infected. Don't apply it on an infected area though. You also need to continue the keflex for at least 3 weeks. I would also recommend giving 1-2 tablets of benadryl twice a day for 3-5 days in order to treat allergies in case this is the primary cause.
