Wally eats twice a day. He gets a chicken quarter in the AM, and at night he gets ground meat with kale, shark cartilage, fish oil, gizzards/organs, and a small bone-thing, usually a neck or a hock.
Granted, he's also a Greyhound and has a fast metabolism, but instead of feeding a chicken quarter everyday you could switch it up and do turkey necks some days so that there is less food and you can feed twice a day without the dog blowing up.
Someone once told me that figuring out the amount of raw to feed is an art, not a science. I believe it
