What's the source for the guy sleeping next to his dog?

I don't remember the name of the comic. Sora wo Mitsukete de la Manana or something like that. But the panel is actually the guy sleeping with a girl he knows. He feels that making a move on her would be a real bad idea, so he's imagining she's a dog to kinda keep himself in line.

It was a pretty allright comic actually.
