Joey had really oily hair as a puppy, but he outgrew it and has wonderful silky hair now. His breeder recommend Biogroom products and told me to always use a conditioner, even though his hair was oily. I've use a lot of different products since then, I'm kind of a shampoo junky, but always go back to Biogroom. The company will send you a free sample packet if you email them and their products are highly concentrated so mix them with water before using. I use the regular shampoo and conditioner, but they have something called fluffy puppy that works well on puppies, anyway, you will get them both along with oatmeal shampoo and their cream rinse conditioner if you ask for some samples.
