Nobody knows for sure the exact origins of the Collie dog breed, or even where its name came from. One specific theory is that the Collie was derived from the same bloodline as the Border Collie.

Another theory concerning the name “Collie” is that it comes from the Gaelic word for “useful”, which definitely describes how useful these dogs were for farmers and as stock dogs. They were considered to be of high value to the the Celts when they first settled in the British Isles.
