My one pup (he is at least two now) “Atilla” is a “funny” dog.  When he wants attention or thinks he is not getting enough, he locks himself in either the bathroom or our office.  And waits until we get him.  We usually hear the door quietly close.

Sometimes when he is in the office with us he will close the door behind us to make sure no other animal will come in to compete for his attention.  We have four dogs and eight cats.  At least this is our guess.  You never know for sure what is in a dog’s mind.
