We feed a raw prey model diet, and if you are an avid hunter it can be done dirt cheap.
You are looking for an 80%/10%/10% ratio. 80% meat, mostly red meat (deer, hog, goat, sheep, elk, caribou, beef) but fish, fowl, and rodents are acceptable additions too. They just shouldn't comprise the majority of the meat source. 10% bone, which should be well covered in meat. Bone-in fowl, rodents, and fish make great "bone" meals. Shoulders, ribs, and necks from your red meat sources are good too. Naked bone (no or little meat on it) is a no-no, as are leg bones from all large mammals and all beef bones. Beef bones and leg bones are too dense and will crack and break teeth. Even in the wild, wolves and dogs don't eat the leg bones of larger prey. The last 10% is comprised of organs. Liver, kidneys, brains, reproductive organs, pancreas, spleen, etc. Lungs and heart are fed as meat, so they would fall into the 80%.
The percentages are averages over time and can be adjusted as needed to meet your dog's needs. No need to meticulously measure out each meal to have exactly an 80/10/10 ratio.
A starting amount for a meal is 2% of your dog's ideal adult weight. Adjust as necessary. If your pup is getting fat, feed less. Too skinny, feed more (especially fattier meat).
