What am I buying when I pick up dog food labeled “for seniors”? What is the best food for older dogs?
Good question. As far as we can tell, there is no standard definition of senior foods and companies can do whatever they like so long as they meet AAFCO (Association of American Feed Control Officials) standards for adult maintenance.
In theory, these products are supposed to be specially formulated for dogs over age seven, but that seems to mean different things for different brands. They could be higher or reduced calories or protein, depending on the particular approach of the company. Just read the bag carefully and make sure the nutritional info makes sense for your dog.
