I don't understand the hole dog scene.
What caused the guy to do it, what even happened and why did he suddenly run off. BTW i watched the film with no subtitles.
shareMe horny - no humans - so... (sheep, dogs, etc.)
He was even hornier than usual because he'd just sneaked a peek on his older brother and new wife making love.
(Don't look for any motivation beyond "horny" ...you won't find one.)
