They need some variety and at least 2 organs. Mine get lean pork in the morning; chicken wing, fish or rabbit for lunch (they will go to 2 meals once Piper is 2) and a ground beef mix that has chicken, beef, liver, kidney, green tripe and their supplements. Buying in bulk to keep it cheaper takes time to weigh and portion. We did have to buy a freezer to put in the garage. I don't think that that is for everyone. But, i'll never go back!
A lot depends on whether you feed BARF [Bones And Raw Food] or the PREY diet, ie whole small animals. Skin and all. Tikva, once I had weaned her, has a frozen chicken wing or neck around 10am. I buy fresh, human quality, pack individually and she has it straight from the freezer. I cannot get pet quality food and definitely not a ground beef mix that has chicken, beef, liver, kidney, green tripe in it. I should be so lucky. I would love to be able to get green tripe but it is not available here. Turkey kidney and heart are things I will eat - in other words she and I eat the same things, but she has hers raw while I cook mine. Tik has meat and vegetables for her second meal - some sort of turkey gizzards or ox lung [very healthy] and turkey liver about once a week. Her evening meal is around 8pm and she has been on just two meals a day since she decided that was enough and her supplements are mixed in with that. I call it her wet meal as the meat, what it is, and vegetables, are defrosted before she has them.
I spent a long time learning about raw feeding for my epileptic dog, which taught me so much. Basically BARF is 80% meat, 10% bone, and 10% offal, but I learned with my epi girl what suited her, and once weaned I started feeding Tikva the same way, just the amount suited to her weight as she is so much smalller. The easiest way was to buy some much smaller bowls so I did not have to weigh anything. If it looked right in the bowl then it was the right amount for her. And believe me, she is a very strong and happy little dog.
But as I have said, and will say again, it is the owner of any dog to feed them as they want and is what is convenient for them. All I will do is give advice as best I can, for those who want to feed their dogs raw. And which supplements they should have to make sure that they are not missing anything.
This is most important with cats. who cannot get Taurine from raw fiood, which is why is is added to cat food.
