Well if you want a purebred I would say borders and aussies are very good agility dogs, or if you want smaller, border terriers. But any dog can do agility- my malamute/husky loves it! BUt here is my advice- rescue a mutt that is active and seems to want to work! That would save a life! Or you can even rescue purebreds, there are several resue groups, and even the shelters/pounds/humane societies have several purebreds in need of a good home!
