Although collies are most often associated with Scotland, one of these strains was developed in Wales. The Welsh Sheepdog, also referred to as Welsh Collie, is believe to have become established in the 19th century when working collies from Scotland were blended with the old native Welsh breeds such as the Black and Tan Sheepdog, the sable or blue-merle Hillman, and the shaggy Old Welsh Grey. Photos accompanying the articles show dogs similar in appearance to other breeds of old working collie ancestry.
Colors are black, black and white, black and tan, tricolor, red, sable, and blue merle.
Ears are small and folded forward. Coats may be rough or smooth. The Welsh sheepdog is good with cattle as well as sheep, and in those days 700 cattle would be taken to London by just a few men and the dogs. One dog would run in front, leading and clearing the way with the others dogs driving from behind. The dogs would keep the stock together overnight and act as guards against robbers . . .
