I am intrigued by the psychology of people wanting a dog the size of a guinea pig....... why not just GET a guinea pig???
I know some of the tiny breeds, such as chihuahuas, are every bit a dog as much as a great dane.....
But when they get even smaller, so small they are unhealthy, live a short time and arent physically capable of doing 'dog things' -- why DO people want them??
Guest -- a Yorkshire Terrier should come in one size only.... they are a fiesty robust little terrier, bred to be capable of WORKING, ie killing rats, spending many hours out doors in the cold, wet Yorkshire climate.
If that is what you want, get a Yorkie bred to the KC standard.
If thats NOT what you want, dont get a yorkie at all!
