Only thing I can think of is obedience training, especially with the leave-it command. It's a yorkies' nature to go after vermin/rodents/small animals, as that's what they were originally bred for. (of course, I've once had a male yorkie that actually got upset seeing a screaming mouse in a trap X_x and our past female didn't bother with rodents but played with and killed cockroaches >_<;;..).
