Suggested Beastiality?

Gotcha!! Made you look here! :-)

Did anyone else see suggestions or hints of beastiality? I thought it kind of weird that the girl grew more sexual intense as her boyfriend said, pulled him tighter when the dog was snapping at him, and grew cold loosing all sexual mood when the dog was chased away and stopping in the middle of highly passionate sex to look for the dog. Then if that wasn't weird enough, a few minutes later it went to the masked party/parade with the two people walking on all fours in matching pajamas and pigs masks, followed by the goat in a straw hat and shawl being guided around by a man. You might also interpet the killing of the dog later to be a solution to a lovers triangle? Thoughts???
