This small but sprightly breed might look like a miniature Doberman pinscher with his black and brown coat, cropped ears and docked tail, but don't let his looks fool you. This canine isn't directly related to the Doberman, but instead counts the dachshund, Italian greyhound and German pinscher as its ancestors. Originally bred to hunt vermin, this dog may prefer killing squeaky toys now, but he'll still alert you to any strangers or unwelcome animals lurking nearby.
Standing an average of 10 to12 inches (25 to 30 centimeters) tall at the shoulder, the Min Pin is called the "King of Toys" because of its sheer excitement for all playthings. This dog absolutely lives to play and enjoys time with children. Because of their size, Min Pins are great for apartment life -- regular games of fetch and trick-teaching sessions will provide the right amount of exercise for this breed. According to the American Kennel Club (AKC), the miniature pinscher is happiest when treated like a regular-sized pooch; while he might adore squeaky toys, don't expect him to enjoy dress up [source: AKC].
