I have a yorkie-poo and a malti-poo. These chews are huge for them. However, they have consistently chewed on them since Christmas. Yes, they're working on the same cheek they received at Christmas. My doctor has 2 bulldogs and he takes them to the office everyday. I always take them treats when I have an appointment. Apparently these dogs wouldn't chew on any type of chew treat. I gave them each one of these cheeks and they loved them. My doctor was very surprised they even tried them, let alone chewed on them. Of course, I'm now the dogs favourite patient. :) -- Karen
