A dog's skin is a sensitive subject, so to speak. We have a terrier mix mutt who has a multitude of skin issues. His mantra is Scratch, Lick, and Repeat. It drive me nuts! Granted, he's a bit neurotic, but the dry skin must make him very cranky this time of year. Once a month, Mr. Mod fills a tub and gives him a good going over, but sometimes, before I catch him, he's washing Chip with plain old generic dish washing soap or his harsh generic shampoo that could strip paint. According to K911, different breeds of dogs have different skin pH balances.
