Well, he is probably just using some regular dog food. My fiancé eats horribly and he and his son have the most foul noxious gas. I try to eat low to no processed foods, and keep grains to a bare minimum, and I also take probiotics, digestive enzymes, etc, and rarely a stomach issue. It is my belief that all the garbage put into pet food is why they have such terrible gas and stool issues, so I want to start right from the get go. The issue is that I have very little time to research and I know nothing about my options, and what may be best. Every marketing ploy tries to trick us into believing their product is the one, know what I mean?
