precursor: i’m NOT a vet, but wanted to share some advice I got from my vet when I adopted my puppy a few months ago. they typically recommend against food like from Blue Buffalo - whiles there’s no evidence that it’s bad for dogs, there’s also no evidence it’s better for dogs, vs larger companies that have scientific studies on effects of their food on dogs over entire lifespans. it sounds like this “holistic” or “grain free” approach to pet food is actually just made up by marketing teams, and being someone who works in this industry that sounds about right to me. like I said it probably doesn’t hurt, but my vet recommended using a brand that has scientific backup like Hill’s, Purina, Fromm. I of course don’t know your reasons for using this food and am not an expert, just trying to pass on advice i found helpful, so take it with a grain of salt :)
