I feed my two boxers Taste of the Wild. It doesn't have any grains in it, and has had great health benefits for the dogs. They now have shiny coats, smell good, and their poops have become more regular, firmer, and they don't smell as bad as they used to.
My male still has gas, but it doesn't smell nearly as awful as before this food. He could clear a room.
My older female plays like she is a puppy again, thanks to this food.
Neither dog ever gets table scraps or people food. They eat enough of their kibble and treats and don't need the extra snacks.
They would probably say that their favorite food is whatever is on my plate...like they would ever get a taste!
