Welcome to the forum.
We fed Buddy all raw for most of his life and he had no real gas problems. But he's eating so much lately that we've started offering him kibble if he's still hungry after 2 -2 1/2 lbs raw. We also want to be sure he'll eat kibble so if we go away we can send kibble with him.
We'll be switching it around, since it's good to rotate protein types, but right now we're offering Blue Wilderness Duck. We have found that he does sometimes get gas when he eats that. Not always though - I think it has to do with how much he's eaten, but I'm not sure yet because it's kinda new and he doesn't necessarily eat it every day even.
You can read reviews of dog food at

I also highly recommend the Diet & Nutrition part of this site that Doreen talked about. A wealth of info there.
