alaskayorkie,
I can't say fortunately, but, I don't have to deal with (much) of a size difference at this time. My Male Sneakers is just under 13 lbs, and (his Sister) My Female Becca is now a WHOPPING 7.8 lbs.
I KNOW I KNOW, I'm trying to get some pictures of Her, so I can submit a App to YTTPC, that is forthcoming...soon. !
As most of us know, Female Yorkies occasionally (
) have an Alpha Wannabe attitude, and Becca is no different. In fact She's conditionally the most aggressive Female I've ever had. On occasion, I have to just sit there and bite my lip, when Sneakers gives her a good nip on the neck, to put her in place. Even at just over one year old now, She's demonstrating some very strong Alpha Female characteristics, and that is is spite of her being Spayed.
I believe that having this situation here now (Sneakers is not altered) is what tuned me in to cockerduchess' situation in this instance. I've often said, that...
"The only way to successfully control a Female Yorkie, is with another Female Yorkie".
