It very well could have been. Size is still a big problem in shelties. They are supposed to be 13" to 16" tall at the withers. Anything more or less is a disqualification.

To many people size is the only difference between shelties and collies, but there are other structural differences as well. The most noticeable is their head. Shelties have a very pronounced stop whereas collies don't.... but in saying that... I've seen many a collie looking sheltie before. I groom a sheltie that makes my giant shelties seem like they are the proper size. He is very collie looking in the face. Confused yet? lol
