She works as a therapy dog and gets a lot of compliments on her coat, not having a bad smell or breath + her shiny white teeth.
I feed with stuff from the butcher, the store and from people I know who get in large quantities of meat (e.g. horsemeat which is to fatty for human consume, etc.).
I try to give mostly big chunks like whole turkeys, chickens or rabbits - or large chunks of meat from other animals. I usually give it in a frozen state so she chews it properly.
