Both of my dogs keep an eye out for me. While out on a walk my dogs won't run too far away without turning around to make sure I am still there and still keeping an eye out on them, too. I love that they do that, they are very protective. However my rottweiler is a very nosy dog, she insists on knowing what everyone is up to and she will often make rounds of the house, going to each bedroom and sitting with the people in there for a little bit then moving on. My other dog used to do this all the time before he went to sleep, but now he is older he can't make it up the stairs as often, so he doesn't do it anymore.
They do spy occasionally like Misha. My rottie, Rosie will often be lurking near a doorway just to know what is going on, then if you turn around she will turn around too and act like she is just going the same way.
