Silky's too..........ours has always had gas, no matter what kind of food he eats. The day DH brought him to the vet when we first got him, he almost crashed the car, it was so bad.We don't change his food often, and he never gets people food. It doesn't seem to matter, always has gas,
When he gets gassy, (even in his sleep) he jumps up, and smells the air, and looks around as if looking for the culprit, and then settles down again.
