Motorcycle knocks down dog?

I just watched a trailer of this movie on a DVD. Looks interesting, but I was a bit shocked to see a scene were a motorcycle rides in full speed violently over a shepherd dog.

The trailer qualitiy is crabby and the scene extremely short and fast, but it looks like it's a real alive dog who even tries to get up after he has been knock down, and it doesn't look tricked or rendered.

I think that's beyond the limits one can accept, just to get a spectacular scene.
