That's a tricky question. Every animal deserves a chance at life.

I believe that if an animal viciously attacks another animal or human being, completely unprovoked, it may be neccessary to put the animal to sleep. Don't get me wrong, I am an avid animal lover, and if it is possible to "rehab" an animal, I say do it.

Here's an extreme example: A dog, with a history of aggressive behavior, lunges through the glass of a closed window. A child is riding his big wheel on the sidewalk, and is mauled by the dog. Does this dog deserve to live, you ask? Everything deserves a chance at life, but this dog needs to be put to sleep, for the safety of everyone. It is an extreme situation, but is not unheard of.

I am probably going to be unpopular for this post, but I believe that the safety of people and animals comes before the rights of those human or animal that have no regard for life. This is why we have prisons (don't ask me about the death penalty, I don't wan to discuss it).

Every sweet creature has the right to live their lives in peace.
