Reds,
Yes, the laws do have the effect of protecting animals. But again, that is not their purpose.
Kennels are often shut down because they broke the law. The law is there because abused animals are often dangerous animals in many different ways. So in essence, their owner is indeed a dangerous person because he is keeping potentially dangerous animals, or is making previously safe animals more dangerous.
In the case of Vick, I would consider what he was doing immoral, but not because I feel badly for the way the dogs are treated. I consider it immoral because he the practice of dogfighting has caused a lot of harm to people in this country. Pit Bulls account for a large percentage of dog attacks, and an even larger percentage of those that result in serious injury (over a third). They are one of the most common dogs in shelters due to the dogfighting "industry", many of them were bred as mean fighters, and when they get old or turn out not to be good fighters they are abandoned, and families end up taking them home. Unfortunately, as a breed, they are often very fine dogs, but when they snap they really snap. Vick was keeping as many of 50 of them, in poor conditions, and specifically trying to teach and breed his dogs to be especially mean.
Animals do not have rights, they have protections, and the protection is all about people. The level of protection has nothing to do with the type of animal, and everything to do with who owns it and what its for, and who would be harmed with breaking the law. Thats the reason the punishments are set up this way.
Killing your own animal: Perfectly legal
Unnecessarily abusing your own animal: Summary offense, you are possibly creating a dangerous animal, or an unsanitary condition, etc.
Abusing or killing someone else's animal: Misdemeanor, you've now harmed someone else.
Poisoning of zoo animals, dogfighting, etc.: Felony. You have quite possibly negatively affected many people.
By the way, I love animals, and have pets and believe in treating them right because I care about them and am emotionally attached. But under the law, they do not have rights. They have protections, even from me, that are meant for the good of mankind, not of animal kind.
