My dog is probably THE MOST allergic dog out here…so I have to weigh in on this topic LOL LOL He pretty much can only have fish, duck, lamb, beef, potaoes, & rice...otherwise all poultry, pork, veggies, & grains are OUT
My vet recommended to start rotating him through different diets because otherwise he will eventually with time become allergic to the one thing I feed him daily & that will become an even bigger headache. We feed Merricks but the only Merricks that I can feed is kibble Salmon & Potatoe & I have to pick out any peas & carrots (he can't eat those either).
So now we started a new food into the rotation...Dick Van Patten's Natural Balance Duck & Potato Allergy Formula which he loves & has had NO reaction to & didn't even get the runs from the food switch. SO I think this will work. For gravy I also add water & fish oil for shiney coats!
