aww - I love labs.
my dad would walk his yellow lab and his basset (basett?) artesian normand (they are bred to go into holes and kill badgers - so they are fearless... might argue stupid).
the yellow lab would hear and see other dogs barking at him and he would sort of wander off on another route like "okay, I'm just gonna uh, go over here, so why don't we... yeah, over here is better, thanks"
but the basset was a fighter and she'd pull over to those dogs and even though she was little, she would get right in their face and she didn't "say" anything, but they would always shut up and have a look like "my bad - didn't see you there - you uh, just do your thing and I'm gonna go see how things behind this house are working out - mmkay?"
that same dog also tried to fight a horse, got kicked and launched about 20+ feet, got up looking around like "where the FUCK is that horse, I'm gonna kick its ass now" - then ran back over to the horse like "bring it bitch!" and the horse finally took off.
I love dogs
my dad's first lab had an indoor dog house that he would sleep in - and when I was little I used to like to take naps in there. the dog was pretty cool about it, but eventually he decided that he'd had enough and he would just go in while I was in there and fall asleep on top of me.
labs are great with kids - I used to ride him, or try to. I would poke him in the eyes while he was sleeping, or lift up his ears and whisper/yell things to him. (I was only like 2 or 3)
very tolerant dogs.
