Nobody likes being flipped off, but this dog really takes it personally.

You may know that when it comes to dog training, you can teach a dog to do tricks with just hand signs. They can learn that pointing down means lay, pointing up means jump and many other things.

This dog apparently knows what it means when someone give a middle finger to you, and doesn't like it one bit. Watch the dogs reaction every time the guy flips him off. That is not a happy dog.

Video is slightly NSFW due to the language and the fact that the growling dog might make the person in the cubicle next to you think you are crazy.
