I just keep thinking that so many have more than one Yorkie so I know it has to work. I also believe it would give Rosie company when we are not home. This is the deal, Rosie is not aggressive toward my mom's dog. She is a female Shih Tzu. So, I know it would work given the right timing. I really think the socialization would help.
I think I have actually got my husband ok with having another one. I worked it really hard.

But he wants another female. Of course, he has every excuse in the world to not get another but I really think he will not care in the long run. Ha ha. We just have to make Rosie believe it is ok.
