Well, i thought this might be interesting for you guys so I
took some print screens of the movie, so you can see for yourself
It's about a son and his mother who commit crimes together and
they are going to kill an old lady and take over her house.
Well the boxer's name is Sophie and she's the dog of that old lady.
At the ending the son opens a door and the boxer jumps aggressivly
on the son but they don't show what happends with the dog or anything.
Here are the screenshots of the boxer scenes(some)
she has lots of pictures and paintings of dogs in the room as you can see.
