My dog. Sorry, but dogs have the same right to live as any human. If it wasn't my dog, my choice may be different. But, my dog looks to me for protection. It would be paddling, trying to get my attention. Do I just let it watch me save someone I don't know? Shouldn't be in a drowning scenario if your safe. If he couldn't swim, but his ego got in the way of wearing a vest, that choice can't kill my dog.
