Louie gets Z Bones. It's a natural treat made by Zukes. The vet recommended them and I haven't needed to brush his teeth since we started using them. They stink, but they make his breath smell great (go figure
). They can be a little pricey, though. The small size is about right for Louie, but I would imagine if your furbaby is a "normal" size yorkie they may be a little big. Louie weighs 10.6 lbs.
