I use "Coat Handlers" shampoo and conditioner on Toto and her hair is just like silk! That's what the breeder recommended and she never scratches or anything. She only scratched one time and the vet found that she was allergic to the dye in our new carpet. After she got over that ... she hasn't scratched anymore. The Coat Handlers makes the light colors in her coat really bright and the black shines. She seems to tangle less too ... when she goes to the groomer she always tangles bad afterwards so I always wind up bathing her again a couple of days later!!
