So far, at 17 weeks, Brian is:
1. very calm and quiet when he's outside/going for car rides.
2. talkative; he barks, growls, aroooos, grumbles, meows, etc. of course, he does all this inside the house.
3. I'm not sure if he'll outgrow this, but he does not chew his food. He just inhales it right up.
4. He used to dig in his water bowl, but he does not do it anymore.
