It's time to switch foods again, but I have had bad luck with the regular Innova EVO, which gave my dog a horrible rash and itching that took forever to cure, not to mention the worst farts, even after I made the switch slowly. I am not sure, but think he was allergic to the turkey, as other turkey products also made him itch. Quincy (a mix of border collie, terrier and sheepdog) has done really well on Solid Gold Barking at the Moon fish formula, and can tolerate lamb, beef or chicken as well. I am nervous about trying the EVO red meat, but it doesn't have any turkey. Another one I have read about lately is Fromm Family Four Star foods. They have a little grain (mostly barley), but it's a semi-allergenic food. Anyone have experience along these lines?
