My mentor does agility with her yorkies, infact just recently she was at an agility show and her male came 2nd (he´s 3 years old).I have seen her yorkies in action, I have been with her to a few of these shows, and there were dogs quite a bit smaller than her yorkies there too (chihuahuas) and they all LOVED it
I recomend.The dogs get TONS of exersize and they really enjoy it
