Hi,
One more thing to be aware of when just getting your little Yorkie home. Hypoglycemia is a condition that you should be aware of just in case, and its most often seen in smaller dogs such as Yorkies. Its when the blood sugar gets too low, and your dog can fall into a coma. Very sad, but very serious. I really urge you to read this Puppy Care info before bringing your little one home.

Its about being prepared so you can enjoy your little one to the fullest!
