Despite the name making many assume otherwise, Gentle Giants is suitable for all types of dogs. That means all sizes, all breeds, and all ages. You can feed your dog Gentle Giants' dog food products from when they're a puppy up to their senior years. Check the feeding guidelines to determine how much dry or wet pet food you buy to feed your pup. Like other "all life stages" pet food, Gentle Giants lists feeding guidelines according to your dog's weight. Overeating, in any dog's case, can lead to obesity and other health problems.
