Nobody knows exactly which terriers were bred together to make Yorkies, but the Paisley Terrier was probably part of the mix because of its long, silky coat. Also there might have been some Maltese bred in. Anyway, the terrier that breeders ended up with was different from other terriers, and it became a whole new breed, the Yorkshire Terrier.

The breed standard says that Yorkies should weigh between 5 and 7 pounds. There are "teacup" Yorkies who only weigh about 3 pounds, but these tiny dogs may only live 3--7 years. A normal-sized Yorkie will have a life span anywhere from 12 to 17 years.
The main health problems that Yorkies have are bronchitis, lymphangiactasia, portosystemic shunt, cataracts, and keratitis sicca. I don't know what some of this stuff is, so if you want to know about it, you will have to look it up yourself. Yorkies don't tolerate anesthesia very well, and they are more likely to be hurt or killed by falls, other dogs, or their owners' clumsiness. Which means that if you have a Yorkie, you should be really careful not to sit on it or drop it or anything like that.
Oh, and one other reason why people probably like Yorkies is because they are just the right size to dress up with cute little clothes. And also you can put bows in their hair. So if you're into that kind of thing, you might want to get yourself a Yorkie. And if you're not, well, you can use your Yorkie to catch any mice that get into your house.
