I hear puppy hair matts really easily. (matt= coat tangles in case you didn't know) My new favorite grooming product is Yorkie Splash and Shine. It's made by one of the vendors here, and it leaves my boy smelling so good and feeling super soft! There is a detangler too which is also a deodorizer.
She has sample sizes of everything so you could at least try them out and see if you like it and not get stuck with big bottles of stuff you'll never use.
