I try to feed natural treats and nothing that is meat based.
I feed the fruit or veggie treats from here, as well as the PB bones and the apple pie bones:

the sweet potato chews are my kids favorites.
I also feed fresh fruits and veggies for treats.
I feed yorkie yummies from chattiesmom in the carrot and banana flavors.
I sometimes will give zukes minis in PB flavor, or the buddy biscuit soft chews in PB... but I rarely give these, I prefer the things made by YT members because I think they care more about my dogs health then some big corporation and I know they arent sticking anything bad in them.
