Hi Guest, you have not left any contact details so all I can say is good luck as Chis seem to be as rare as rocking horse poop at the mo:D!!
They are becoming more popular but generally have small litters and bitches in particular will be kept by the breeder to continue their line. I've just read a post here that someones friend is importing 2 from the USA so that gives you an idea of their scarcity.
Good luck anyway, remember to go to a reputable breeder(lots of info on here about finding one), unfortunatley puppy farmers latch onto these kind of breeds and exploit them and their prospective owners.
Hope this is of help
Emily
