Also, I think I've decided my canonical dogsona would basically be this old critter with a huge unwieldy rack of moose antlers attached.
He causes a lot of damage when overexcited, and has to put more presence of mind into going through doors than he really has.
He's a clever boy, but mostly in ways that get him into trouble. He doesn't know any tricks. I think I'm recycling my little-used basselope persona's name "Wormwood" for him.
@zebratron2084 nice
