If you're totally set on getting this Korean puppy and feel you have covered *every* single, solitary base you can to somehow get an idea as to the nature of this breeder, and then still feel it's the right decision in all aspects.....
....then, what I'd advise is that you hire a pet courier to pick up this tiny little, living, precious, vulnerable being; it's the right thing to do here. Shipping this pup via cargo is *NOT* a good decision for this little puppy in any way, shape, or form. Please, animal lover-to-animal lover, don't do that
. I feel like if you are willing to pay that much for an animal, then you should be willing to pay more to make that animal safe.
I would ask that breeder, via Skype, and without warning - to see the parents, or more of the facility, or whatever else you think would be valuable in any way.
As far as age - she could very well be about 8 wks if she is truly a tiny one.
Just please be careful, cognizant/aware, mindful of what you could be supporting, in the big picture of things. I really cannot say whether or not there are "ethical" breeders doing this kind of thing...? Most would say no, bc of what's being marketed here, as a...commodity. Every action has consequences we can't even see....but would maybe break you if you did. Ya know what I mean? Tread carefully.
I do think, though, that it's very possible to have a dog this size who is perfectly healthy, just smaller. Size does not define health. I do wish you and this puppy the best of luck!
I don't think that's necessarily true, but I could see where part of you might think that initially due to wider-spaced eyes like this. But the tiny ones (my Marcel included, who is 4.5lbs, but seems almost tinier for some reason...?) can look *exactly* like this as healthy puppies.
The clinical gal in you will like this stuff too - remember Jrsygal's (Elaine) "Jersey" - who had hydro, but looked just like any other yorkie,
here.
Also, a Dx of hydro can't be done without the clinical signs (Clinical signs are similar to those of congenital hydrocephalus and include changes in behavior or training, circling, head pressing (a term used for pressing of the head up against a wall or other structure), listlessness, loss of vision, pacing, restlessness, and seizures. - from VCA Hospitals) -- and U/S, CT, MRI, and EEGs also can be done.
