I grind the meat and mix it with raw spinach, broccoli and carrots. I add brown rice to the remaining broth and then mix it all together. Sometimes I add seared calf liver (not good for them raw). Got curious one time and ate a spoonful, was surprisingly not bad. Great way to also dispose of meat too long in the freezer. Also older dog gets multivitamins with his meals. Makes about four days of food for two large dogs. Week to ten days for one large dog. Cheap but healthy dog food when I use venison because it only costs a bullet.
You might want to just research boutique dog foods and taurine deficiency. Dogs were getting heart failure from special super expensive foods like you are preparing, when given it in isolation, and they thought the food might have been Taurine deficient.
The irony is, they said the cheap cornmeal they used in cheaper foods going back decades, just because it was a cheap filler, was supplying taurine, so nobody really knew it was needed.
But your dogs sound appropriately spoiled. Good job!
