Thanks for the advice, LDMomma.
I just finished reading an article that says that chicken wings aren't good to give dogs because the size makes it easy for them to choke. They said the same about chicken necks. I've been giving both of these to my dogs with no real issues, but I have to cut up the chicken necks as one of my little ones has trouble eating them whole. Here's the article if you're interested:
Myths About Raw: Can toy breeds and small dogs eat a raw diet?
I also give lots of eggs in different consistencies. Sometimes scrambled, sometimes raw. The next thing I want to try is giving the egg with the shell intact. I saw a video on youtube and the dog has a great time figuring out how to open the egg.
I can't feed ground meat on a prey model diet since it totally goes against the principle. One of the differences between BARF and the prey model is that the prey model requires everything to be whole or as close to it as possible. Dogs clean their teeth while chewing on the meat and bones and this advantage is lost if you feed ground meats. There's nothing wrong with feeding like that! It's great because it's raw, but I want to try the prey model specifically because of the teeth problem.
I'll still have to decide if I can stomach giving them tripe. It grosses me out completely! Where do you get the tripe?
