Canine groups, also known as dog breeds, are classifications that categorize dogs based on their characteristics, behaviors, and purposes. The American Kennel Club (AKC) recognizes several groups, including Herding, Working, Sporting, Hound, Terrier, Toy, Non-Sporting, and Miscellaneous. Each group has distinct traits that reflect the historical roles of the breeds within it. For example, the Herding group includes breeds like the Border Collie and German Shepherd, known for their intelligence and ability to manage livestock. In contrast, the Toy group features smaller breeds like the Chihuahua and Pomeranian, which are often kept for companionship. Understanding these groups helps potential dog owners choose a breed that fits their lifestyle.
