Yes, Lady gets recurring staph infections. She has been diabetic for 7.5 years so she has a very weak immune system. I constantly battle staph, especially on her neck area where she gets her insulin shots.
I try to check her skin daily when I brush her. If I can catch a lesion right away, one application of Clearasil usually takes care of it, believe it or not.
Benzoyl-Plus doesn't seem to have fragrance added from the ingredients and smells odorless to me. I use it maybe every 4 weeks or so, but only on the areas Lady is having trouble with. It's very drying so I don't like to use it on her whole coat, although this brand has a moisturizer in it.
Cephalexin works best when she needs a prescription. I've never heard of Clindamycin for staph, but maybe it works when other antibiotics have not? I just had to take it for a new crown that abscessed and ended up needing a root canal. That stuff will destroy your digestive system so watch out! Diarrhea is a common side effect.
Have you ever considered collostrum/transfer factor? I absolutely swear by it. I started Lady on it three years ago when she was just a mess and her bloodwork was so bad her vet estimated she only had six months to live. Her insulin need is half what it was before I started Transfer Factor.
