Hundförvaring

I do not speak or read Swedish, nor do I even know if this is Swedish, but based on the pictures I'm led to believe that the Swedes (or some people who deploy both the "å" and "ö" symbols in an apparently un-ironic manner)  are now storing their dogs in lockers.

On snowy streets.

Can this be true? I can imagine this working once per dog, but what canine with more than an ounce of self-respect would suffer the indignity of being stuffed into one of these boxes after they've learned what's about to happen?

And who cleans these dog lockers? Are they air-conditioned in the summer? What problem are these things designed to solve? I picture the Scandinavians as a rather cooperative and peaceful bunch, but are they abnormally prone to pet theft?
