Base Jumping Dog – Cool or Cruel?

I know that a dog is a man's best friend, and we love doing everything together, but  I can't decide if making this dog participate in a base jump is cool or cruel.

The dog attached to the back of this guy's wing suit doesn't seem to be stressed out by the whole ordeal, but you can't help but wonder what's going through the dog's mind as he goes flying through the air. Take a look and tell us what you think. Cool or Cruel?
