I've been feeding raw for many years now, to roughly 7 dogs ranging from 4lb to 90lb, couch potato pets to working dogs. I've also fed 4 cats on raw. I balance nutrition by feeding a large variety of animals and body parts. Muscle meats, bones, feet, hearts, kidneys, liver, spleen, tripe (stomach), lungs, whole small animals (ie. chicks, mice, rats, guinea pigs, rabbits, ect ect) whole heads from large animals including brains and eyeballs....Even testicles. :HistericalSmiley: Nothing is off limits in our house. We always get rave reviews from every vet my pets have seen about their excellent health (Backed up with great blood work results!), especially their beautiful teeth and muscular bodies! My aim for my babies is balance over times rather than "every meal", just as I do for myself and my family. I don't claim to know everything about nutrition but I do know what works for the pets in my home. :thumbsup:
