Lovely name! Your not supposed to bath them often so just if he's dirty or smelly really! I had no choice as blizzard had been out on a very long walk through muddy grass and fields and he went white and came home brown! I feed him wainwrights large breed puppy kibble atm along with raw food from butchers, like chicken carcasses etc, ur riddick is a bit young for them but you can start him on chicken pieces with his kibble, and move on to wings etc when he's bigger and able to eat bones etc x the kibble suits him just right and keeps him solid as they have such sensitive tummies! I can't even treat blizzard as it will give him the runs! So I treat with chicken pieces or wainwrights treats, expensive but worth it! Xx
