There are a lot of misconceptions about grain free food and whether or not it is good for dogs. The truth is, there is no one-size-fits-all answer to this question. It depends on your dog's individual needs and health condition. If your dog has a sensitive stomach or allergies, then grain free food may be a good option for them. However, if your dog is healthy and does not have any dietary restrictions, then there is no need to switch to a grain free diet. Grain free food tends to be more expensive than regular dog food, so you should only switch to this type of diet if it is medically necessary for your dog.
