We had Jetta on Canidae for awhile, when we got Bo, we switched to Diamond Naturals Chicken and Rice as it was cheaper and still decent. they have been on it for 2.5 months now...Jetta has horrible gas...constantly letting it loose, lol....stinky too...I heard yogurt helps, but can't really afford it...so we deal with it...but...boxers are gassy to begin with, lol...and then the food swtich....and then their GI issues can all add to it...you may just have to start wearing clothespins on your nose!
