Experts generally recommend Goldens eat a complete and balanced commercial dog food, but there's no one-size-fits-all feeding chart. Your dog's individual needs will vary, based on their age, weight and activity level. Talk to your vet to figure out the best diet for your dog. Golden Retrievers can develop food allergies, which may cause itchy skin and excessive licking. You can manage these reactions by working with a veterinarian and changing their diet.
