The "Aussie" are flexible and quick dogs. It always likes to work it doesn't matter if it is for fun or for real. The dog is so earger, which means it is one of the best breeds for agility. As the dog is easy to train, you can get a dog, that you can win all masterships with.
You only need to know how to train the dog. I started to put my mark on my puppies at the age of 5 weeks. Go on steps and boards, small and spread, "unsafe" and shaky things, through concrete pipes.
