With my dogs its cow or other such hooves. We used to feed the good, ski on Ambassador hotdogs to our K-9. The dog was no dummy and held out for the good stuff to break its training of not accepting food from other than its handler. The officer absolutely hated that. It was best done in the winter or on an devilishly hot and humid day in the summer as it was almost as painful to open the windows as to keep them closed.
That's awesome!
