Lizzie was a lucky girl to find you. I would think you did go thru doggie culture shock going from I. greyhound to yorkie! Her lack of socialization in the first months of her life as well as the possibility of abuse or at the least lack of proper care is the reason she is the way she is. She may overcome it with constant care, training, and understanding. I have to agree with you how beautiful they are when they run through the wind with their hair blowing back. That's always a sight I love to watch, too. Welcome to YT.
