Can't imagine its the food. My 2 samoyeds do fantastic on Nutro Ultra and Nutro Natural Choice. My son has Malamutes who also are on the same food and they also are in excellent health. Its been appx 4 years for being on the Nutro and i would never change. You know, its a 81 year old company that only makes dog/cat food. Bet your dog had some other issue. Hope it is well.

My dogs had the same reaction on nutro ultra, like thousands of others have! Nutro is owned by Mars and they do not make only dog/cat food. They make lots of things, like candy and junk dog food. Google it, thousands of dogs have had the vomiting bile problem. It's a trash dog food...look it up on dogfoodanalysis.com
