Ok... quick summary and similar-series breakdown for Dog Days:
Guy with inhuman physical abilities gets teleported into a world full of dogs and dog-humans; they have friendly wars, which if a person gets petted, they're out; fanservice; girl gets abducted; fanservice; guy saves her; more fanservice; he gets teleported back to his world.
It's as bad as Sacred Seven, but with more anime-ish style art.
