Hi everyone. My Petite Basset Griffon Vendeen (PBGV) has started to get stinky from frolicking in fields during our walks. I bathed her about two weeks ago and have heard that you shouldn't bathe rough/wire coated dogs very often. She's only 6 months so she has a bit of softer puppy hair still. How often is too often to bathe wire/rough coated dogs? What shampoo would you all recommend?
