6. Shetland Sheepdog
The Shetland sheepdog may look just like a miniature collie, but they started out as a local variant of the Icelandic sheepdog found in the Shetland Islands. These small dogs were then bred to rough collies to create this unique breed. Playful and energetic, the sheltie is equally at home working on the farm or in the ‘burbs, showing off in agility, flyball, and obedience.
5. Doberman Pinscher
The Doberman pinscher was originally bred by a German tax collector for protection on his rounds. Modern Dobermans are far less aggressive and make wonderful family dogs that love to play and are extremely loyal.
