That is the first time I've tried to post a link so have not idea if it will work.
I also know absolutely nothing about this site so am not recommending or substantiating anything about it. As I said I just saw it posted on another thread & was surprised to see a standard for height for Yorkies.
Really just wanted to know if this has any merit to it. Thanks for replying.
