yorkies have been breed down in size for fashion not health or for a better breed, breed standard does not mean the yorkie will be good enough for show. look at all the breeds of dogs that now have breathing problems due to having such flat faces cos thats breed standard
all you have to do is look on here at all the sick yorkies with so many more problems, the breed never had so many problems and maybe the size of the breed has something to do with it ie breeding the so called runts together to get smaller pups, these were called runts has they hadnt done very well in the mum then not been as healthy as the other pups ie with feeding and putting on weight normaly, if someone came on here saying they were gonna breed there sick yorkie everyone would go mad at them.
