I have 4 kwigy bo Alex (1 small, 3 large). ZoE outgrew the small pretty quickly, but I didn't care for it anyway, as the pockets were too tiny to be useful. If I had a tiny pup and was looking for a small size bag, I'd go with a different bag in hindsight.
The large I like as the pockets are bigger & I can actually fit a wallet in a pocket, a checkbook in a pocket, etc. I have a putty (with faux snake handles), a gunmetal and a black patent croc. The putty, I love the colour, but the handles started coming apart early on. The gunmetal is nice for the times I don't want black, but the black patent croc. has held up the best. I keep that one in my car, so I always have it with me if I need to make an unplanned stop while I have ZoE with me.
Here's the gunmetal, the black croc, and the putty, and then the putty with Zo hunkered down.
