Ok,
It looks like I got the yorkie fever :-P ... I couldn't stand Mike being alone and growing up solo, so...
I present you Molly, mikes new friend... I just got her home last night and looks like Mike and her will be getting along fine, I was worry at first trying to find a friend for him because he is really Hyper... but it looks like I found him a perfect match :-).
Molly is also super active, and the age/weight difference is not that much of a big gap.
Mike is 15 weeks and weights 1.5 lbs, Molly is 11 weeks and weights about 1 lbs so they should be fine when playing together.
She was a little shy/submissive at the beginning but little by little she was gaining confidence.
Ok, so here is a pic of Molly and Mike and a little video of them having fun fo the first time...
