I have NEVER heard of feeding raw meat to big dogs to prevent bloat. I don't think it would have anything to do with it! Having been a part of raising two Saint Bernards and one Great Dane, no one ever said anything about feeding raw meat. I wouldn't worry about it with Binx, either.

What you DO have to do is avoid strenuous exercise right after eating. Never do that with any large-breed dog. A woman I know lost her Mastiff to bloat, and it's so quick and heartbreaking. Her new dog is an Italian Greyhound, opposite on the size scale.
