I am not familiar with the term RMB.
I switched my dogs to raw "cold turkey" kibble one day, raw the next. They didn't have any problems at all. I have made a couple mistakes, but I'm getting better with it.
Ruby would not eat the turkey legs I gave them last week. I don't think she liked the flavor. If I cut the pieces really small she'd swallow them whole, but she wouldn't eat it off of the bone. Riggs just chowed down, and he thought it was Christmas when I handed him Ruby's turkey leg. He's so funny.
They get meat on some days and bones on others. The veal ribs are soft enough for them to eat, the cow ribs are too hard and they shatter. All of the veal bones are very soft actually, and they eat them very fast.
Both dogs got a little plugged up, so be sure that you give them veggies at the beginning until they get used to it.
and a funny story about raw... this weekend we had a vegetarian visiting and I pulled out the one pound chunks of ground beef for Ruby and Riggs. They were still partially frozen but they are used to that. Riggs wolfed his down and them puked it right back up on the kitchen floor. I thought Elizabeth was going to hurl. When I fed them on Saturday I called her into the kitchen to watch again.
She came in. She looked like she was being called to the rack. I told her she didn't really have to watch, I was just teasing her. She looked soooooo releived.
