i use sunsilk straighten up shampoo and conditioner on smokey because that is what my breeder uses on her biewer that is a show dog.....biewers are known for having wavy or curly hair.....it really works.....smokey is a yorkie/biewer so his hair is very hard to manage...actually i just shaved him down for the first time....his hair was smelling really bad after just one day because we use belly bands....but you talk about soft...boy is he soft....and he loves to sniff his self after his bath.....lol....usually if they are gonna have skins problems from the shampoo you will know it in about an hour ofter they are completely dry.....hint: try it on his tummy(any new product that you every use) if it dont break out in an hour chances are he wont be allergic....good luck.....im still learning......
