There are tons of sites where you can go and research diseases, etc. specific to the yorkshire terrier breed. Some of them are better than others and you need to research to make sure the info you are receiving is indeed the most UTD and viable. I will be happy to work with the administrator of this site to do this; I think there should be different sections such as "Health", "Behavior", "Housebreaking", "Vaccination Protocol" and others that I can't think of now. I see that there are lots of folks on this list that are newbies to yorkie ownership and I think this would be a tremendous resource!
