how much are you feeding at one time and how many times a day? splitting it up into two feeds might reduce the onslought. I had a lab with terrible gas (it was the food but i didn't know better then) and a friend dosed him up with mylanta every night, I don't recommend that because i don't know if it is ok, didn't do him any harm but he swallowed a tennis ball and that didnt' bother him either. He was very big. I know there are additives you can give, canned pumpkin i think is suppose to help bind that stool up a little, and adding some yogurt might improve his overall digestion. I am sure someone here knows more about this end of things then i do.
