As a puppy I have been using Pet Silk puppy shampoo. It works wonderful for puppy coats. I have sample bottles of the Chris Christensen shampoo, conditioner and the Ice on Ice. Which I love. They sell sample kits so you can try the products before spending the money on big bottles. I have been growing Galen's coat out also. The puppy coat loves the mats.
The Ice on Ice spray is nice to get out mats. I spray it on and work it out with my fingers mostly and bring in the comb to finish. Love it.
