They are also not uncommon, at least here there are loads of breeders probably more than the larger size - you will find as much variation in them as the larger versions. It also means that there really isn't a lack of a gene pool to work from. Since the Aussie itself didn't join AKC until 1980 and didn't even have a set standard until 76' I think you can decide which "breed" is real and not real.
I've always been of the opinion there are loads of breeds with different sizes that are uncontroversial. I just see the smaller version hate in the mini aussie case being a case of sour grapes.
I was trying to type up something about the history, but didn't feel knowledgeable enough about the subject to post it, so thank you for posting this
