Yorkies are loving and loyal. My husband felt a little like this when we first got a dog. Now she is side by side with him every night. If this is truely how you feel and are not joking...I hope your feelings will soften too just like my husbands did. Your yorkie will only want to please you. He/she will look for your acceptance and try to make you proud. Compared to your experience with the outdoor dogs you've had in the past , I think you now will finally know what people mean by "mans best friend".
Good luck with your new family member! I hope it's the best winter you've ever had
