While Noah is very polite and accepting of all dogs, I think he definitely likes people better. When I take him to the big park, he will run a good hundred yards away to greet another person with a dog, but he always comes right back to me. Once he says hello to a dog, he generally likes to just stay near the group of people, rather than running around and wrestling with the other dogs.
I'm not sure if this is because he's always had my other dog to play with or because he's submissive around other dogs. Today a 4 month old puppy that was smaller than him was able to sit on Noah and not let Noah up!
Some doodles I've met seem to love to play with other dogs and can't get enough.
