I have periodic problems with mice, so it will be interesting to see if Puddin' goes after them. My Fox Terrier kills pigeons (we have a huge back yard and many, many bird nests) and I've had to scold her for it, but she's really only doing what comes naturally for terriers. I would be devastated if she killed one of my weaver birds, tho.

Terriers were selectively bred for high energy, quickness and their instinct to kill small creatures. Back in the days of the Yorkshire mines, Yorkies were actually engaged in rat killing contests and their abilities were awesome! Your Yorkie is only doing what comes naturally.
