I've used coat handlers on my adults and older puppies for a while now. there is one called sungold through pet edge that is tearless for pups, i still use that from time to time. you could just use a tearless baby shampoo until your puppy gets a little older then switch to something that will be better on the coat as it grows. its up to you and i dont frown on any paticular bathing method....as long as you keep them clean!
i will say that the CH clarifying is good on the follicles and promotes hair growth. i dont put shampoo on my younger puppy's faces anyway. i wash that part with a warm washcloth. just the body and butt in the shampoo..
