I'll try this again, If you see two posts I apologize - the page froze up.
Anyway, I use it on our black Lab Lucee but not on Bella our Yorkie. It's meant for dogs that shed and it works great for Lucee
. The Shih Tzu does not shed. I got on the furminator web site and they have "recommend breed" and "not-recommended breed" lists to determine if it should be used and the Shih Tzu is on the "not-recommended" list. But the Yorkie is on the "recommended" list, strange huh? Maybe they don't realize that the Yorkie does not shed?
