Most rights have no bearing for animals  The right to dignity would mean nothing to an animal. Animals are incapable of being humiliated and are not harmed by being reduced to human servitude. A dog is not ashamed of its nudity or having to eat out of a bowl and wear a leash. Animals happily copulate and defecate in front of humans and other animals. What exactly an undignified action might be for an animal it is difficult to say.  The right to education, to vote, to fair trial, to be innocent until proven guilty, to privacy, marriage, nationality, religion, property, freedom of thought, freedom of speech, workers rights and shelter all seem impossible to apply to animals.  If we specially tailor rights to animals then how is that different to the status quo where we have certain laws protecting animals?
