I'd also like to provide an update on my own experience with the raw diet. My new puppy, a golden retriever, is now 8 months old and he's absolutely thriving. He's 70 lbs, is strong and energetic, and has a glossy, soft, long coat. I thought I would share my diet info and what I've been doing so far since it seems to be working so well.
I butchered an entire cow elk just for him. I fed him the heart right off the bat. I chunked up the liver and kidneys and put them in a large bowl. I then chunked up all of the meat from the elk, packaging it as I went. I would sprinkle a few pieces of organ into each pile of meat before wrapping it up and putting it in the freezer. When I was done, I had maybe 75 lbs of elk meat that had liver and kidney mixed in.
I've been feeding him twice a day. As a puppy, he got 50/50 kibble and elk with a raw egg and fish oil for breakfast. For dinner he had 50/50 kibble and elk. I got him a good quality fish oil made for pets and followed the dosage suggestions.
Now that he's older, I do the 50/50 kibble and elk with a raw egg and fish oil for both meals, breakfast and dinner, still following the dosage suggestions for the fish oil. Actually, I just recently ran out of elk and have been using chunked beef stew meat fresh and direct from a butcher. There's no organ meat in there, which is a bummer. I haven't figured out yet how or if I want to mitigate that. Maybe I'll just stick it out like that until hunting season rolls around.
Oh, I almost forgot! As a bonus...I saved both both elk femurs with chunks of meat still attached. I gave him one and froze the other for later. It's been phenomenal for the teething process while also giving him the nutritional boosts from the bone marrow.
Anyway, that's what I've been up to and the pup is doing amazing! It's not the easiest thing to butcher an entire elk just for your pup but if you have the means to do so, the pup will absolutely thrive on it.
