In light of how many Yorkies are being stolen from their homes, and literally snatched from their people's arms, I'd begun to seriously consider going against my instincts and microchipping Abigail.
Then, I ran across this:

I'm looking to add another female to our family. I hope the breeder we choose does not practice chipping, just because it's the 'in' thing.
