Prey Model Raw is a homemade, species appropriate diet that replicates the diet of a wild canine.
As seen is Sadie's bowl above, 80% raw, boneless meat is a majority of the diet. This includes things like gizzards, breast meat, tongue, heart, lung, tripe, trachea.
Bones should be non-weight bearing bones like poultry feet, necks, backs and wings, pork and beef ribs and tails. Yes, these types of raw bones are safe. It's COOKED bones that cause worry - because it makes bones brittle and can cause bones to splinter. Raw, non-weight bearing bones are pliable and digestible!
The category of "other organ" includes secreting organs pancreas, kidney, spleen, testicles, brain and ovaries.
The idea is that this model resembles whole prey, which is what dogs consumed in the wild. Eventually you want to work up to as many different proteins as you can - the more the variety the better! Dogs can have most meats like chicken, turkey, pork, beef, rabbit and fish.
