dog food

What kind of dog food is better for a dog that farts a lot? Anything thats helps your digestion?
I have a pit bull, and courier Snapshot not sure if only the race or my dog, he doesn't sick people food. Ive tried a few brands of dog food (dry food wet pedigree and science diet) and farts SO much. Hes an indoor dog so the fart is a problem when I have guests over for dinner. Anyone have any suggestions? He and my husband are the loves of my life. Hes our baby and prevents me from feeling lonely while my husband is in Iraq. The money is not a problem. Just do not want he is not feeling well. Im sure hes not feel very comfortable with gas all the time:)
Add a pinch of baking soda to the dog's food every time feed it. This care for the gas and soothe the stomach.
