I haven't fed raw for very long yet, but so far so good.

Border Collie Lover: Did you switch them over cold turkey? Sometimes if they're switched abruptly they go through a "detox" period of a week or so since their bodies aren't used to the rich food. That being said, some diets just don't work for some dogs, and I think you're a great owner for figuring out what works best for your dogs.
