I make my own treats for training because I have a golden retriever that is a bit fat. So I make some nice healthy treats for him and for the pitbull mix I use some treats with higher protien because she is real hard to keep weight on.

I also give milk bones , rawhide chews ect. heh we made jerky this last summer and we ahh kinda burnt the crap out of it so we used those for a month or so as treats! Doggies LOVED them!
