Trina and Zo both have blackheads on their tails. My vet suggested using an acne cream (instead of the alcohol pads) that has 5% benzoyl peroxide. I've gone to Target, Walgreens, Walmart and Shop-n-Save, and all they have is 10% creams. Well, Walmart had one that was a small tube of cream, and a bunch of pills. Does anyone know where I can get some 5% cream? I can't believe it's this hard to find! Sue Trina Sugar Zo [Posted in FML issue 4425]
