I have a question if you are looking at the first site there are 10 different ones. Is there one in particular? I know that the Coach Op Art Pet Carrier is discontinued.
A dog carrier is like a handbag. Everyone likes their favorites. I would look at the features. That is the most important part. To keep my little one safe.
I have the Jaraden Soho and I love the features.

Good luck in your choice
