I've tried so many!
My personal favorite is Minksheen shampoo and Pek conditioner. I just got the Yorkie Splash and Shine products. I don't like the shampoo and conditioner as well, but they really smell good! I am liking their spray on detangular though.
I also love the Vellus products...they smell the BEST! They even have a Morning Mist fragrance spray that is amazing!
