Almost a third of the American Kennel Club's (AKC's) 153 breeds could be considered small dogs. With these pint-size pets spread throughout five of the seven AKC groups, 20 are tiny enough to be proud members of the Toy Group and all 48 will fit nicely in your lap. If you are considering adding a small dog to your family, you will be joining millions of other small-dog owners who know that, as with other things in life, good things come in small packages.
