32. Shetland Sheepdog
People believe that the Shetland Sheepdog is a miniature version of a collie, but they’re actually two different breeds. They have a lot more energy and were bred in a separate area of the United Kingdom, specifically Scotland. Although Shelties descended from collies, they are their own breed. People bred them to be herding dogs as well, so they do need much exercise, or else they’ll start putting on a lot of weight that can be bad on their small joints. Grooming is a must, as well as taking care of their teeth since they’re prone to dental disease.
