Shetland Sheepdog and Rough Collie - YES, separate breeds. one is a miniature being the Shetland Sheepdog like a MINI ME of the Original Rough Collie! Great for people who would love a full sized Collie but not the Room!
I grew up with one as a child and she was so loving and protective. She lived to be 19 years old and was a constant and devoted companion. Love you, Lassie. (Not very original name I know but we were young)
