Transport bags for small animals that do not cut a financially out of the shoes, are mostly a waste of money. I've also made some bad buys. But this bag is great! If one does not need it, you can fold it small and flat. My Bolonka Zwetna - 25 cm shoulder height - loves the bag. I even housebroken get him so because I have locked him up there at night next to my bed so that he answers, if he has to. We took the bag and with Nicky in the train to Norderney, where she has served as a cozy bed. However, the transport is great: I've always had problems when I have to carry a heavy bag over a shoulder. Not only that something sliding down easily, I cramp me then also always the case that I have pain for days. Not in this case, because you can roam over the head and adjust in length so that an arm is below the pocket. But if you need both hands, going, too. And the little dog can stick out everywhere. Only the upper lock one must be careful when closing well, because my little one had very quickly figure out how the zipper rises ... (grins). From its dimensions, the bag is allowed even for air travel - so what more could you want? And she does look good too! Nicky and I recommend the bag!
