If it's an actual animal abuse- that is, the animal is harmed-then yes, the people responsible should be dealt with according to their countries laws regarding animal rights. No one should be able to profit off of material where they have directly abused the rights of a living person or animal.
I don't think, though, that a dog who humps some human whore is going to be particularly traumatized in any way by the whole thing. So, disgusting as you may find it, wanting to have it banned is really just an example of censorship based on moral grounds...which I personally am against. Imagine if governments got the decision to ban everything which they deemed immoral. Morality is subjective, you see. So maybe they'd ban your favourite cartoon because it happened to offend THEM.
Fascist dictatorship around the corner.
