I received a sample bottle from a fellow Yoyo and she sent it to me at least 3 mths ago and I bathe my two Yorkie's almost weekly and I love what it does and I like the smell too! The first time I used it on my Silky Lexy my husband noticed he difference immediately. I brush my girls regularly so there is very little matting if there is any its under their arms from the grass. Sometimes I will add a little of my conditioner for extra softness. I get lots of compliments on my girls coats. I think it does work differently on the different coats so I guess it all depends on what sort of coat your Yorkie has. If anyone has a gallon they don't want I'd like to take it off your hands.
