Interesting. I was hoping it would be something that we could control through behavioral means without any other physical means, but definitely something to look in to. We did at one time. He is much better now. Not sure if he grew out of it or what, but we didn't change his food and he has because much less gassier. We feed him high quality food and also use a brake-fast food bowl that slows him down. Allegedly one of the things that make the gas bad is if they take in a lot of air when eating. He still lets them go every now and then but its not unbearable.
