It's a personal preference, but I now have 2 re-homed Yorkies. After getting the first one (male) in May 2011, we babysat a friend's ex-show-puppy Shih Tzu and she and Brody had so much fun together...they were both about a year old at the time...that when Sunny went home, Brody would just go and lay on the spot on the floor where her kennel had sat and looked sad at us. I knew he wanted/needed a playmate, and went looking for a rescue or re-home Yorkie. It only took 2 days to find her, Mia, and we picked her up the 3rd day...had to wait 'cuz travel was involved.
Mine were just over a year at the time and the adjustment was instantaneous, even before we brought Mia home, maybe because they are still quite young.
We have not regretted our decision and it feels like they have always been with us. But, again, the decision needs to be based on your own situation...all of it...baby's needs, too.
You will put up pix of your next one, right?
