I'm buying Henri a stroller!

I wasn't planning on buying one for him because I didn't think we needed it/would use it. Henri loves to walk and so that is what he does, but I go to events that are dog friendly and bring him along. It is NOT easy having him on a leash at these crowded events, I can't even count how many times he was almost stepped on! Carrying him gets tiring and its hard to do much at the events when my arms are full, I have even tried a carrier but it doesn't help much. I don't want to leave him at home as these events are great socializing for him and he loves the attention he gets from people, he is such a little charmer

I am buying a stroller. Decision made. Time to shop.
I probably won't be buying it for a few months yet but I figured I might as well start looking it to it now. So, YTers, I have a mission for you! Please post pictures of your pups in their adorable strollers and please answer these questions: 3 wheel vs 4 wheel? Brands? Where can I get a decently priced one that won't break the bank? What color?
Thanks!
