Although I don't have a dog right now (mine have passed away) I fed them Eukanuba. I had been feeding my standard poodle the same food that her breeder had been feeding her, but she had a "gas problem" (if you get my drift). I mentioned this to my vet and he suggested Eukanuba. I switched over gradually, making a 1/2 and 1/2 mixture of the old food and the Eukanuba and gradually increasing the Eukanuba and decreasing the old food. The end result......no gas!! My cats eat Eukanuba too and since they are getting older and sleep so much I give them the less active formula and they seem to enjoy it (no fussy appetites!)
