I didn't say that I grouped kids and dogs in the same category, you assumed that. Of course I value my kid's life over my dog's, but I'll value the life of either over the life of someone threatening them. Seems like the pro-Vick/anti-dog crowd can't help themselves to try to bend over backwards to create arguments that haven't actually been made. As for your property statement, yes dogs are property that can be bought and sold, but I bet no one's ever been sent to prison for abusing couches. Dogs certainly have more protection under the law than standard property.
You're free to place whatever value on a dog's life that you will.
You'll notice that I haven't tried to lecture anyone on how they should view a dog, I'm simply stating my own personal views.
