Spencer is a 2-year-old black male. He is good with other dogs and does not try to dominate at all. However, he doesn't seem to be okay with cats. He barks at them if he sees them (even if they are not close to where he is). if properly introduced to a cat, he will leave it alone. In addition he rides very well in a car. We've taken him on walks, and he's learning to walk on a leash, he is getting better, though. Not sure about kids. He's still very much a puppy and so he is still a lil bitey, so probably not younger kids.
