I homecook now-I like knowing exactly what I'm feeding my dogs. If you want help getting started, there are many YT'ers that home prepare food and were wonderful mentors to me as I began homecooking.
If you're looking for a commercial food, Canidae and Blue Buffalo are both great foods. I used to feed Blue Buffalo to my dogs, and they did well on it. However, you may need to try different foods and find out what works best for you and for your dog. Most manufacturers will send you a free sample to try if you call or request one online-I know both Canidae and BB will send samples. You can then see how your dog likes it and research the ingredients in each of them before investing the money in a larger bag.
