Just the other day someone brought their dog in for coworking. Most dogs, if you give them your palm they will sniff and lick at it and it will be cute. But this was a timberwolf-husky breed and he got SO excited at my hand that he quickly progressed to cramming as much of my forearm in his mouth as he could fit(which was somewhere between a third to half of it, coming in from a side angle). Given his size it was slightly worrisome, but he was gentle and left only the smallest of marks. Then he jumped up and slobbered my face to complete the job.

At the same time, this dog wasn't so cooped up and energetic that he could not control himself, and he napped a good deal of the time. He was clearly getting bored at his sleep-deprived owner still sitting around in a beanbag chair working and barked that this was not acceptable, but his interest was maintained by meeting the new people and smells in the space.

It was just a great reminder of how varied breeds and individuals are. I've met rescue wolves and they are extremely shy, requiring total stillness to get any trust; little dogs tend to be domineering yappers; show breeds are often anxious. Of the lot, the "working dogs" are probably the ones that are hardest to keep up with daily, since they need either plenty of exercise or stimulation or both.
