What if?

What would you do, in this position:
You are far off land, in a very tiny boat, with your best friend, constant companion, the dog. You hear a faint splashing, you squint and see a drowning stranger, struggling to stay afloat-- he's waving at you, almost screaming. Would you-

-kick your dog out into the water and let the stranger in the boat?

-keep your dog in the boat and paddle away from the stranger?

-jump out of the boat, and let the stranger in with your dog?

I would grab the stranger, let him/her on my tiny boat, and stay in the water floating next to my boat (holding onto the edge) until we got to land...you know, like Leo D. did in Titanic. But then again, his ass died because that b**ch wouldn't take turns to allow him some time on their little floating device. So, I guess my dog and I would switch on and off floating in the water until we reached land. Even better, me, my dog and the stranger (once he gathered his strength) would go in shifts between the boat and water.
