You need to put some bottoms on poor Spanky, her goodies are all hanging out!! Poor thing. Looks like an allergic reaction to me. When Duke was little he was allergic to all shampoos (because I bathed him too often , well he slept in bed and I did not want him all stinky LOL) My vet told me I could use baby shampoo so now that is pretty much all I use. I never have problems with fleas. Well that is not true around November sometimes I will notice a couple then we get advantage and use it for a month or two and that is it. I hope her little bottom is all itchy free soon.
