Dog Carrier

I snapped this photo on the way to work this morning. 

I see this more and more in downtown Chicago: Pedestrians carrying small dogs in rolling suitcases. I'm sure some pet product company makes rolling dog carriers, but this is probably a less expensive and more convenient option. As long as the pooch is comfy and happy, I'm tempted to say go for it.

However -- the dog is not on a leash. Little Fido or Fifi could become excited and run out into traffic. The suitcase thing is probably not in the best interest of doggy safety.
