My last GSD and now Bear (this morning in fact) will usually make the rounds and "check" on us. I will get the cold wet nose in the face, usually in the middle of the night. I tell him , it's ok and to go back to bed.
I think Balen is very bonded to Kolton and he is doing his job of making sure that Kolton is ok....and then letting *you* know that he's ok.
