Happy Birthday! 
 
  
I know it sounds simple to just let your dog breed with another Yorkie and then in a little while you'll have a couple of sweet little puppies.
But I think if you do even a small amount of research, you'll change your mind. I think there is a lot of things that can go terribly wrong.
There are people who devote their lives to developing the best Yorkies possible. They breed out genetic defects.
