Dogs in windows?

Had another thought. I wonder if I have discovered a new trend or if this is something that has been going on for ages, but i just never noticed. The past week i've started to find dogs in clothes shops. At first i thought it was just that people for whatever reason didn't want to leave their dogs alone, but after seeing this one today i'm starting to think it's a sales trick. If you can't get people interested in your clothes, put a cute puppy in the window... whatever catches people's attention...
