These dogs are not that common in the US and Canada.
They aree NOT the result of crossing a golden retriever with a border collie. If you cross a black skinned golden with a black and white border collie, you will get black puppies with some white on them.
The collie-type is a very old strain, and it is possible that BC’s of this color are a source for the golden retriever and yellow Labrador coloration. After all, border collies are, at least partially, derived from the collie dogs of the Scottish/English Borders, which is where an important ancestor of both the golden retriever and the yellow Labrador originated. The Tweed water dog/Tweed water spaniel may have had some collie ancestors.
Further, it is well-known that wavy-coats were crossed with collies, some of which could have been of this color.
Now, this color is not the same as the sable you see in rough and smooth collies. If you cross a golden retriever with a sable collie, you will get dogs that are mostly black. This “true red” color doesn’t exist in the rough and smooth collie gene pool. It does exist in shelties and BC’s, and I’m pretty sure it can be found in English shepherds, too.
I should say here that I’ve never understood why liver colored border collies and Dobermanns are called “reds.” They don’t look even remotely red to me!
