I usually give mine enough for a few days. According to that link I posted, they are supposed to consume at least 15g per day. I've never weighed out how much food they get but I usually just use a scoop.
thanks for the helpfull information guys. Somebody can tell me how much to feed them dog food and how many times a day?
I free feed mine. Their feed hoppers are always full of dog food. If you make a feed hopper out of wire you can just keep it full. They really won't over eat on dog food. They will just eat enough to stay in good shape. Also, the hopper will keep them from wasting food.
