I use Plush Puppy on my Bullies... i really like it. it makes them smell really nice and it keeps their coats rough/wirey (?). the kind i use is "With Henna"... The discription reads:
"Natural All Purpose Shampoo with Henna
This is the shampoo to use when shine is required. Suitable for all breeds where coat texture is tobe retained e.g. Akitas, Siberians, Shelties etc. Recommended also for short coated breeds that specifically don’t want a softened coat e.g. Weimeraners, Bulldogs, Rottweilers and most Terriers. A good all round shampoo to use when the coat texture is healthy and shine is the focus. Suitable for dogs with most skin problems. Derived from organic sources with extracts of henna, alpine herbs and lichen. "
I strongly suggest it. Zero had a bath about a month and a half ago, and STILL smells great
