One of Dawg’s favorite treats is a simple rawhide bone. He gets one a year (at Xmas) because he is allergic to beef. The rest of the year he gets treats made out of chicken and sweet potatoes, which he likes, but he really, really loves rawhide.
It makes him throw up, but doesn’t have any long-term effect. So once a year Dawg gets to have his rawhide and we get to clean up the mess later. It’s worth it — it makes him happy.
