I just bought Teddie a rolling puppy kennel, I guess that would be similar to a stroller. Soft and cushioned, purple in color with croc-trim and a sherpa lining. It has handles to carry when you travel via plane, the wheels come off easily for that. It has a telescopic handle, dual sided entry with both sides mesh and see through, and a zipper up top so Teddie can stick his head out and enjoy a top view. The wheels are 360 so you can move it any direction, not just forwards and back.
Here's a link to it if anyone wants to see what a nut I am.
