They have recently started to use some organic ingredients, so I think it's a pretty cool brand. We used it when Mia was a puppy. I liked it because you can add water to the dry food, and it becomes soft with a gravy-like sauce. Excellent for picky puppies!
There have been rumors on the internet recently about how Merrick uses left-overs from its rendering plant in their pet foods, but that is not true because their dog foods do not have by-products as an ingredient. If they did use it, they would have had to list it as by-products.
We sometimes give Mia the canned food. She loves Mediterranean Banquet. Oh, we also buy a lot of Merrick treats, like Flossies.
