Well, I've successfully switched Shady over to Solid Gold Wolf Cub after doing another extensive research of doggie foods and brands and all that jazz. Its only been about a week now, but so far so good. Whew! I can breathe again. I wanted to mention that I found these 'Gas Busters' tabs at PetCo that were not only reasonably priced, but rather effective too. Hopefully we won't be needing any more of those though.
