Does your dog keep an eye on you?

Both of my dogs keep an eye out for me, especially when my husband is not home. My husband has to leave for work pretty early, so he is usually out of bed before I am. When he leaves, my male dog will get into our bed and lay at the foot, facing the door. If am out of bed, and working, (I work from home) no matter where he is, he always lays facing our front door. I feel he does this to make sure no intruders come inside the house. As for my female, she is always right on top of me, and follows me everywhere, as if she is my bodyguard.
