I dont know much about the Mini Aussie, but maybe you should check them out? Im currently a sucker for Aussies. That being said, Pembroke Welsh Corgi came up several times on your breed selector things. Also, whenever I take those, it always put the dog I have waaay down at the bottom. And I wouldnt trade either one of them for the world. So I think research is the best way to go about picking a dog.
