Something about yourself

Keeping things going with macstansbury's "tell me something about you" theme,

Here's one, I'm interested in your responses. I'll call it "A Severe Mercy", with apologies to C.S. Lewis.

Your moron puppy, who has been tormented by squirrels in the back yard, finally bags one who doesn't get to the tree in time. You manage to get idiot dog off of it, and a brief examination seems to indicate Mr. Squirrel ain't long for this world, however you are no doctor and it's possible he could pull through. You just don't know.

What do you do?

a) pull the dog inside and wait for Mr. Squirrel to join the choir invisible
b) let the dog finish him
c) call a vet and spend an afternoon saving a squirrel
d) send him across the river Styx with a .38 and a penny in his paws
