Diamond had a very bad case of hypoglycemia when she was a baby but now she seems to be fine. She does shake here and there and usually it is if she's cold, nervous, excited, sometimes they just do it for attention too.
They are extremely smart dogs and they know just what to do to get your attention. Diamond has peed the size of a dime on the rug just because I was eating and not paying attention to her, she is quite the smart Yorkie!!!!
