WOW
thats some difference a Yorkie or a Rotweiler!!
It doesnt get any better than being lucky enough to live with a Yorkie, its a shame that you were put off by health issues, the vast majority of Yorkies live long healthy lives. I think sometimes the problem with reading a forum is that alot of people will post when theres a problem and maybe that ends up looking like the breed in general is ill all the time.
bit like if you ever read the leaflets that come with prescribed medicines we'd never take another pill or potion if we read what side effects you may get.
but having said that you gotta go with what you would be happier with and i hope everything works out great with your new pup.
but........ ok i'll say it ..... theres no comparison and yes maybe i am a bit biased!
