Huh??

In my neighborhood it is not an unusual thing to see many, many people pushing strollers at any time of the day. However, there are people in my neighborhood who have a dog stroller. A DOG STROLLER! Wha-??? I have stared at this man pushing his pink dog stroller (yes, I said MAN pushing a PINK dog stroller) and I just cannot get a grip on why you would ever push your dogs in a stroller. At first I thought, well, maybe the dog has an injury and can't go on a walk to, you know, take care of business. But this has been going on for months. And, couldn't you just set the dog down in the back yard and let it go?? To beat it all, these dogs are little tiny, Paris Hilton-esque, yorkies. Who is this guy?

Now, I know there are some serious dog lovers out there. I happen to only be a dog tolerator. If anyone can shed some light on this, please, feel free.
