We attended a yorkie meet-up this past spring and had one of these same agility sets, (just for fun, no serious agility) it worked out great for our purposes. It's not a quality set, but then I'm sure you're aware of that bc of the price.
Btw, the pause box is nylon webbing strips, staked to the ground in a square shape.
To get the yorkies to weave through the poles, you had to bend over just in front of the yorkie offering them a treat. Which meant the person was weaving backwards through the poles, while bending over....
LOL....we never really used the stop watch, as only one participant's yorkies actually finished the entire run.
