I used to cook for them but realised they were even healthier when I just fed them raw food. And it was soo much easier. Figured I'd never seen a wolf or coyote bbqing their food, or grazing in the barley fields either, and it's much more energy efficient not to cook so I just passed out the chunks of boney meat and let them have at it. There's a yahoo rawfeeding group that goes into rawfeeding in detail but my pups are fine for now (4 years into it).
