Out of my 4, I have one that is a bolter. Chasing only makes it worse. The only reason I have been able to catch him is that I have gotten down on the ground and acted like I was going to play with him. One time it was even in the mud.

I do the treat thing with "come" but when he is loose he is so happy---bounds with tail straight up and ears back--- that a treat doesn't even register.

These little Yorkies can have such stubborn streaks.

Not too long ago I bought 4 ex-pens to connect together and put them out our patio door which is where he escapes from. (DH hasn't had time to put up a fence which will cost around $6,000.) Still don't trust him. Know it is just a matter of time before he figures out how to climb the fence. I'm out there every second with him. Well, hawks are another reason.
