How sweet of you to do this. That makes you a wonderful person. I think you will be surprised how loving a 12-yr old will be. If this little yorkie is healthy right now, then you don't really have any difference in care for a 12-yr old than a younger puppy. They can be just as wild and crazy as a yorkie puppy. Just watch the eyes for cataracts and keep an eye out for uti's. Regular vet checks and watching for congestive heart failure are just a few things to do. They need exercise just like a younger yorkie. In fact, the exercise is probably more beneficial to an older yorkie than a younger one, because it helps their organs to work better. Good luck to you.
