I use these-
Amazon
I've only seen them locally in one store but they are Jackson's absolute FAV!!! They come in a few different flavors. Very very limited ingredients which I love, each with a different protein source. The bag is pretty big and lasts us a while because the pieces are easy to break (it's kind of like soft jerky) so we get 4-5 treats out of one piece.
Venison, chicory, lecithin, sea salt, mixed tocopherols, garlic
