Still debating on a dog breed. I've always liked the looks of the Aussie much more then the Border Collie from a personal prospective. After going on the USDAA's web site I see that the Border Collie wins like every Agility Trial in their height class... With a few Aussie's in the mix. My question to you is this... Is the Border Collie more athletic then the Aussie or is it just that the Aussie is lesser in numbers in the U.S. and that is why the Border Collie's always steal the show. B/C to my they seem like the same dog just slight variations. Thx in advance.
