I'm SO glad you posted this thread! I was worried there were no "off leash yorkies" out there. My bf was convinced that our yorkie would be safe off leash, even though we've only had him for a month, so my bf put him in his ungated front yard....and needless to say: OFF TOBI WENT! Tobi ran for 3 blocks before I could catch him. Everytime I called his name he only turned around and then ran away faster! That little devil!
