This is ONE of the carriers I have for Princess. I have used this one recently while traveling to/from Georgia in addition to taking her in her metal kennel for the ride.
I just love this carrier I am including a link for. Princess is a small yorkie, 8 months old and weighs less than 4 lbs. right now. She has plenty of room in this carrier. She loves it and enjoys going places with me.
It is very comfortable for Princess. Very well made and has a nice sherpa bottom that is also removeable for washing.
