I have a 3 year old Great Pyrenees and a 4 month old German Shepherd. They routinely tell on each other such as if one makes a mess or the other steals a stuffed animal it should not have. Additionally, they will also rat out my daughter if she does something they don't like. They look for me if there is trouble such as the time my daughter locked herself out of the house one morning. I woke up to the Pyrenees whining at the bedroom door. Since he was frantic I followed him downstairs and let her back in.
I seem to recall a study that demonstrated dogs vs wolves in how they handle problem solving. The short of it is that if a dog comes across something it can't solve on its own (ball rolls under a couch, etc) it will very quickly find its human to help. Wolves, even tame ones, will not go to humans for help. I believe this was done for similarly raised dogs and wolves so seems to be a side effect of the domestication process.
