Do dogs learn better or more quickly with other dogs present?

Like imitation learning. As humans, we sometimes learn by example and imitation, where we observe what other people are doing and that knowledge forms in our knowledge base. It got me thinking, does this happen with dogs as well (or any other species of animal for that matter)? For example, when my dog wants to go to the bathroom, he goes to the door and whines. I never taught him to do that, but he just does it. I was speaking to a friend who has 2 dogs, and she expressed how she can’t seem to teach the second dog how to let her know when it has to go to the bathroom, but the other dog does it. Shouldn’t the 2nd dog observe what the other one is doing and learn from it?
