9. Shetland Sheepdog
At a first glance, this breed looks similar to the more famous breed, Collie, or Lassie (how people often call them), and many dog lovers believe they share a common ancestor. But, when you put them together, side by side, you’ll see that not only they differ a lot in size (Shetland is much smaller) but that there are other differences as well. This breed originated in Scotland and was used as a work dog, mainly to guard and herd the livestock (as the name “sheepdog” denotes it). This is a good dog for families (he will get attached so much that he will guard the entire family), very obedient, intelligent and easy to train. The Shetland Sheepdog needs to be often exercised, as they are very active.
