I got my pomeranian here about 5 years ago, and though he is the biggest pomeranian I have ever seen, he is the nicest dog in the universe.  He was older when I purchased him, and I was afraid he would be mentally damaged from being in a pet store all that time, but the staff were so kind to him. 
The staff at the store played with him and gave him extra attention since he had been there so long, and I think that made all the difference.
