I buy chicken backs by the case. Some weeks I buy leg quarters by the case. Some days I just walk by and toss them a few backs or a couple leg quarters. I have a bunch of chickens so the dogs get a lot of eggs. During hunting season deer meat and deer guts. I also buy ten pound bags of beef fat trimmings. Once or twice a week I make a stew of sorts with rice, beef scraps, dog food and rendered oil from beef fat.

barf.com usually has a rep in most areas and they are usually willing to do co-ops to buy in bulk.
