Yorkies were ranked the 61st most at-risk breed for pyometra (which is mid-range for all breeds studied), 24th most at risk for mammary tumors (which is in the top quartile), and 36th most at risk for developing one or the other (high second quartile). IMHO, based on these data, the rate of pyometra for unspayed Yorkies (21%), the rate of mammary tumors (25%), and the rate of one or the other (39%) provide a compelling reason to spay Yorkies before the first heat, UNLESS they are being used as breeding stock, or have a health issue that would make the risk of spaying too great for a particular individual.

Been saying that and I hope that people rethink trying to frighten people on this forum into not spaying their female yorkies.
