This is what I use to carry Wosie around. I have two other carriers, but this is by far her favorite. It is for use up to 10 pounds. She can stick her head out, or can be all the way inside with the top secured. It has screening on the sides so it has great airflow, and she can see out when she is all the way in. It has a pocket in the front for treats and leash, and a pad inside that can zip out and be washed as needed. I got it at Petsmart, and I think it cost $25. I like it very much because it is hands-free. Also, when she is inside, no one can see her, so I pretty much take her everywhere. It's great!
Good luck with your search!
