There Is No Official Teacup Dog Breed
People may like all sorts of different dogs. Some will like big agressive dogs and others like the smaller and friendlier ones but everybody just has to love a teacup dog.
There is no official breed of teacup dog yet everyone knows that they are small dogs perhaps tiny dogs and since there is not a specific brred the teacup can come from any one of several official breeds of dog.
They tend to be bred from the smaller examples of the toy dog breeds but at the end of the day a teacup dog is whatever you want it to be. If it fits into a large teacup it is a teacup dog.
