animallaw.info is the Michigan State University College of Law site dedicated for to the animal rights.
The site has a lot of legal information concerning pet rights, wild animal rights. Another interesting feature is the forum where you can get legal advice concerning particular cases. For example, what if a cop shoots down your dog after it ran away? Do Iguanas have rights? Are you having problems with your veterinarian? What happens if I believe my neighbor poisoned my dog? All of these are valid questions that you might have and which deserve a proper answer. Plus, since animal rights may slightly differ from one state to another you should keep yourself informed. Remember that misinformation not only leads to confusions, but also to legal problems.
