|Legally there is no such thing as a Tiny Toy, Teacup, or Teaspoon Yorkie.. The Yorkshire Terrier, BREED STANDARD, is a TOY DOG weighing 4 to 7 lbs. That is the only legal description for the Yorkie, that I've ever seen. Some of the Puppy Mills, have bred them larger and larger, because they have larger litters, and need less attention, therefore making them more money.. I've seen them up to 15 lbs, and heard them called Miniatures.. Legally, they do not exist, and cannot be shown.
AKC only recognizes the 4 to 7 lb, TOY dog.
So when people claim there is no such thing as a Teacup, etc., they refer to the Breed Standard, recognized by AKC.
Those of us who breed the tinies, understand this, but for lack of better titles, we do call them by these names.. We also breed especially for the tinies, so whether you accept the descriptions we use or not, the tinies do exist, and they exist mostly because we work hard to create them, just as we work hard to make sure they are healthy before they leave us..
The term Teaspoon, is my own, and that's what I call any puppy with an estimated adult weight of under 2 lbs. A Teacup is between 2 & 3 lbs, a Tiny Toy between 3 & 4 lbs.
Breeding 2 dogs of the same size means nothing, breeding two small dogs, means nothing.. To breed for the tinies, you must start with small dogs, that come from several generations of small dogs.. Just because a male weighs 2 lbs, doesn't mean he will throw tiny pups, if he came from a large background. It is my belief, there needs to be about 7 generations of small dogs, before I am confident the puppies will be small. I DO NOT breed a female under 3 & 1/2 lbs, not even to the tiniest of males, from the tiniest of backgrounds.
