Best dry food for Farting Dog ?

Question
My labradoodle is wonderful in all aspects except he seems to let out some pretty foul smelling farts. I feed him the Kirkland Super Premium dry food (Lamb & Rice & Vegetable formula). Is there a different dry food you could recommend? I also have a Shih-tzu who eats the same food without any problems. They both seem to love this and it's economical since it's a Costco brand.

Answer
I think it is really a random thing, that some people have solved it by switching to Kirkland.  I would just try anything that is different, perhaps a chicken and rice product that is low in vegetables.  I know thousands of Labs do quite well on Pro Plan with very few problems with gas.  There isn't any evidence that dogs do better on the premium chows.  It is all speculation and marketing hype.
