I just took my Alex bag out on it's first trip and it worked out wonderfully. PLENTY of room for my stuff and Lexie was very comfy in it. I got the large size and both furbutts fit in it, but that would get REALLY heavy! I even took her into an Arby's and no one was the wiser! It does seem kind of big, but only one person knew I had a pup in there because her friend has the same bag!
