For Lovetodream88 Here is what my sister says about the teacup term being used
I was born and raised in Belfast, Northern Ireland. I married an American serviceman and moved to this great country to be with his family. We have been married for 42 years and have 4 wonderful children and many beautiful grandchildren. My family and I love Yorkies and they have been a part of our lives for many years.
We have a small kennel located in Greenville, South Carolina, U.S.A. I have shown dogs for many years, but have retired now from the show ring. As a responsible Yorkie breeder I strive to produce puppies as close to the AKC standard as possible. It is my goal to produce puppies that are sound both in body and mind while maintaining the outstanding temperament that the Yorkshire terrier is so well known for. I have chosen each of my Yorkies to ensure quality, healthy lines.
The Yorkie standard is
4 to 7 lbs., though some can be smaller and some larger.
A Yorkie smaller than 4-lbs. is sometimes called a tiny or a teacup, though a normal 4-lbs. Yorkie is itself quite small. There is nothing in the standard that refers to either tiny or teacup. These tiny/teacup puppies should be just as healthy as a bigger dog if born healthy and from a good line. They will need extra care as they are more
easily injured. A 2-1/2 -3-1/2 lb. dog can make a wonderful pet in the right home setting. Due to their smaller body weight it can be riskier to put them to sleep for surgery. At times I have
these smaller tiny/teacup puppies which should mature under 4-lbs.
