dogs diet?

Question
My 8 month old lab has been eating Evo dry and can food.  Prior to that she ate Wellness.  Both brands I believe are good, but my problem is gas!!  After eating she passes gas.  Is it the food?  I have tried gas aid products--no luck.  Can you help?

Answer
As near as I can tell, premium chows such as EVO and Wellness are no better than the common brands when it comes to gas and soft stools.  I have seen many cases where people go through a half dozen ''good'' brands before finding one that works.  I have fed 19 different dogs common brands and only had a couple I had to change chows for.  

I would look for another chow that has different ingredients and try it.
