Belly has been on Vital Essentials raw frozen nuggets for 5 months now and doing super on it. It's based on the prey model . She is about 50 lbs. and get's about 2 1/2 cups a day. Time is my enemy so I don't have any spare to portion out meat from the store and freeze it. She also get's enzymes, pumpkin,grizzly salmon oil and local honey. I recently read an article on FB that said raw feeding cuts back drastically on chances of bloat.
