Hi! My puppy, Jesse, is about 7 months old and after originally being on Natural Balance fish and sweet potato when he came home from the breeder, was switched to Innova Large Breed Puppy. He loved the food and has done well on it. The problem is that now he seems bored with it and doesn't seem all that eager when I feed him. I mentioned this at the pet food place I go to and the manager told me that I might want to alternate foods(gradually), and he gave me a few samples to use as treats. I think one was California Naturals and the other was Fromm. Well, Jesse could of devoured each bag whole if I had let him. I remember reading how some of the people on this forum do alternate their foods and change up the protein source with older dogs. My question is if that is advisable to do with puppies? If I do change it up a little, what would I alternate between?
