Yorkshire Terrier puppies! I believe they are possibly the smallest Yorkshire Terrier puppies available. They weigh only 20 pounds at 12 weeks old which means they are charting to reach a tiny 2lb as an adult Mum is tiny for breeding at only 3.5lb. But she is also one of the prettiest Yorkshire Terrier you will see Dad is my super tiny 2lb 6ouces Yorkshire Terrier Both mother and father are available to view here with the puppies They are ready to leave our home.
