what an ahole!!!! you'd think... there's a fence there for A REASON!!!!
I hope Blaze doesn't try to wiggle out...
I would really have a talk with your neighbor and tell him that yorkies get stolen way too often... if he doesn't understand that... then he's not a friend (or good neighbor)...
He should be keeping an eye out for your babies while they're out there.. not taking them from you to see how badly you're going to panic
Good Luck!!
