Dog is eating but is not gaining weight

If your dog is eating but not gaining weight it could be due to the amount your are feeding or the type of food you are feeding. If you look on the back of the bag it will have feeding instructions for your dog's weight. Also it could be due to how active your dog is. If your dog is very active and plays and runs a lot, it could be burning extra calories causing it to not gain weight. If this is the case you can try feeding an "active" formula food. It could also be due to a thyroid problem or even diabetes. If you think your dog is under weight and can't gain any weight you should have an exam done by a veterinarian to determine if the diet needs to be changed, or if some bloodwork needs to be done to be sure everything is functioning properly.
