I’ve used the Vension and Duck and Turkey. My dog is a picky eater and wasn’t really a fan of vension. I think it was too exotic of a protein for him. I think the food is fantastic and I recommend it to a lot of people at work. But it’s not for every dog. If you have a large to giant breed puppy please read the thread Hound Dog Mom made about foods for large to giant breed puppies. NV is one that has some formulas that are great for large breed and giant breed puppies
