My Pekingese is allergic to fleas. Although I have her on Advantage, and there are no visible signs of fleas, my VET says that is what is causing her to have little red bumps. Per my vet, I tried her on 10 mg of Benadryl 3 times a day and a food supplement and hypoallergenic shampoo. I only bathe her once a month because I am afraid if I do more it will weaken the Advantage. Help, she is scratching quite a bit.
