So we winded up giving a whole thigh tonight to both dogs to incorporate bone! You give bone daily right? I also bought some RMBs today!
When first starting raw, it's generally better to feed bone daily. For my dog, now that's she fully transitioned and we have an established regular menu, we do a bone-in meal about once every 3 days. We do bone-in meat along with her "ration" of organs, and then 2 days of MM only. (this is just how it all worked out percentage-wise for us.)
Are gizzards a muscle meat? Besides liver what other organs are there truly? I'm not able to find much besides different livers. I did however find some brain which I already cut up. So far we only have beef liver and chicken liver. We also have gizzards but I think that would be muscle meat? I don't know where to find kidneys.. We also picked up some rabbit and we picked up some chitterlings and pig tails. I think pig tails can be considered RMBs right because there's a lot of bone and meat? So many questions!
Edit: just read gizzard is a muscle meat!
Questions are good, never be afraid to ask!
"Other" organs include kidney, pancreas, spleen, testicles, and ovaries. Kidney is probably the easiest one to source, I've gotten kidney from a local butcher and a local meat processor (I did have to ask specifically though, they didn't just have it in stock). I'd recommend looking into local sources that may allow you to "special order" organs. Another option is to order organs from a raw-food supplier like MyPetCarnivore (we looove MPC!), Hare Today Gone Tomorrow, Raw Feeding Miami, etc.
Gizzard, Heart, Lung, Tongue, and Green tripe are all fed as MM. Chitterling is intestines, and doesn't really have much (if any) nutritional value to your dog. Green tripe(stomach) on the other hand, is a powerhouse food!
I feed chicken almost exclusively as my bone source (and I have a much smaller dog) so I'm not super comfortable recommending bone-in cuts that would be appropriate for your size dog - this can also depend on their confidence in eating and how intense of a chewer they are.
I HIGHLY recommend joining the Raw Feeding Community on facebook
! They have a collection of files with good basic info, as well as more in-depth information. There are a lot of really knowledgeable people on there as well, and everyone is great about being welcoming and helpful to new raw feeders.
