I'm probably the most particular mom in the universe when it comes to what I allow my girls to eat or chew on. Cindy's Yorkie Yummies were the very first things I let them have other than what I made and their beef femur bones. I finally broke down and ordered the Himalayan chews. They all seemed to love them for a couple of days, and I liked how they only finely crumble instead of having larger pieces come off, but they haven't touched them in a month. I don't understand. I really would like them to chew on them more. Maybe they got tired of chewing for a couple of days without getting enough off to eat.
