The carrier is very lightweight, yet well constructed. As you can see from the photo attached, it is plenty of room for our 11 pound Shih Tzu princess. The carrier also has padding and more than adequate ventilation.
I bought another one that was too small so this one turns out to be just right, glad I bought it. It is clean, well made and well designed carrier for a medium size animal. Lots of air and see through mesh so the animal feel safe not confined.
So far we’ve been on one plane trip and the bag has worked very well. It holds its shape and everything on it works. My 10lb cat seems quite comfortable in it, and it easily fits under a Southwest airline seat.
