I don't have a stroller yet, but I'm looking for one on Ebay. I used to wonder why people bought strollers for their dogs since walking is so good for them, but after owning a yorkie, I can see why. Sometimes they get tired and you end up carrying them. I don't mind carrying Jake, but a stroller would make things so much easier. Plus, you can take them to the mall with you or pretty much anywhere. I think they would come in handy if you're on a picnic...it gives them a place to lay down and rest comfortably in the shade. And, it helps to keep strangers' hands off of them when you're out in public.
