I start pups at 3 weeks with raw ground beef. I make little marble sized meatballs and pop em right in their mouths. They suck on em and "get it" in just a few tries. Next thing you know you'll have a bunch of little babies crawling up your legs to get more.! Bones I wait till 5 or 6 weeks. Raw chicken breasts are great. Lots of meat, so they get the "ripping and tearing" down, and softer bone. Some can't get thru the bone at first, but the do have fun trying. Chicken necks that I bang up a bit with a rubber mallet are useful. They are real fun outside, so each baby can grab one and go munch in their spot.
In their mush mix they do get the ground beef blended in with goats milk and baby cereal too.
From what we've learned/read try to think of using the whole animal, so meat, and different organs, and bones (that aren't too hard). You can sorta gauge by the stool if they are getting too much or not enough of something. Too hard of stool-too much bone, or runny stool maybe too much organ or not enough bone. Really it's pretty easy.
Also, you are not suppose to feed "weight baring" bones like legs cause those will break the dogs teeth. You can use those bones for "recreation bones" to just have fun and chew on, but when the meat is gone take it away. The only bones on a cow we can feed are the ribs, so we also give Zelda chicken quarters and backs.
I think Pat (my husband) is going to get Zelda some...let's just call it veal (so I don't get sad) from the farm. I think those bones would be okay for dogs.
Raw is good for the dogs coat and you wouldn't believe how white their teeth get. Plus there is hardly any poop out in the yard for the kids to step in. LOL Audra
due to government regulations you cannot get the organs from them
so we end up paying a normal butcher who pays a carrying agent who pays the abattoir so we have at least 3 sets of profit added on to the price if not more
