Is the stroller in Petsmart a full size stroller? Mine is the same size as a baby stroller, but the one I saw at Petsmart the other day is a smaller version of mine, but still a happy trails brand. I think the bigger one is better. I got mine at
www.radiofence.com. I don't have a problem with the zipper at all in mine and when I saw Petsmart I thought I should tell you about the different sizes. Also, I got a blue stroller so that it looked more like a real baby stroller, even though the pink is really cute.
