Shetland Sheepdog Dog Breed. NOT a miniature Collie. Collie is an entirely different breed.
The Shetland Sheepdog, or Sheltie, as it's affectionately called, is by all appearances a miniature Collie & while it does share some genetic traits w/ the Collie, it isn't considered to be of that breed class. The Sheltie is a member of the working class of herding dogs & it continues to excel in that area. W/ the ability to learn commands in less than 5 repetitions, it's considered to be 1 of the most intelligent breeds. An alert watchdog & an affectionate companion.
