I feed my border collie a raw diet, and Heinz is right. We use Mountain Dog raw food, which is pre-packaged with fruits and veggies in it. Here's a blurb about it from their website, www.mountaindogfood.com:
We use chicken from inspected sources..... NOT from a rendering plant! This chicken ( comprising mainly of backs, thighs, drumsticks left from the deboning process) is then either ground ( bone-in) or left whole for those that prefer to feed whole raw meaty bones.
The ground chicken is then put into forms and frozen.
For the meat / vegetable mixes; we mix the meat with a vegetable & fruit mixture containing 70% meat and 30% veggie/fruit. We encourage you to add leftover veggies from your meals.
Carrots, Celery, Apples, Yams
The vegetables, fruit and chicken are all ground together and then frozen.
