Also, if you want to do "people food," here's a homemade recipe that some boxer people use. It's a big thing in dobes right now and dogs LOVE it. Looooooooooove it. It uses a pressure cooker, but you could do it in a normal pot. With as much as you can make with it, and for the price, you could feed her forever!
