I have not done agility with my yorkies but I am starting them in agility in summer. Yorkies tend not to do agility do to their small size. Especially if you want to compete, your yorkie has to meet a size requirement to do so and most yorkies do not meet that size requirement because they are so small. However, there are alot of yorkies that compete in mini agility that is designed for these small dogs. It is such a fun sport, I know my yorkies are going to love it, they love to run and man they are so fast!!
