As the snow thaws, the stray dogs are beginning to re-appear. I was getting to know the pack near where I live (and the one on the way to work) last year - only by sight I mean; they are neither friendly or unfriendly, but would certainly attack if threatened.
These strays produce a variety of responses. Some people, particularly old ladies, leave them food. Others put collars on them, so that they won't be removed and killed. But others find them unsettling, both as potential dangerous and as yet another symbol of what is wrong with Moscow, its inability to be a 'civilised' city on par with London or New York.
