Kill or not.

I disagree with Carlson's decision to kill the dog. One reason is that, in my opinion, life is more important than health. And also I think it is not good to kill such a helpful animal that helped Candy from its birth. In my opinion, it is not okay to shoot an animal until it hurts you. But sometimes animals can be used to make medicines. Also we need animals for food.  So it is okay to kill an animal for a reason. These are my opinion about killing animals.
