My German Shepherd has to take medicine for an allergy. Most of the time, my wife hands me the pills to give to him. I tell him its time for your medicine "open your mouth" and he just opens his mouth and waits for me to push the pills behind his tongue.
He also seems to have a clock inside him. Every morning at 9am he starts harrassing me, nosing my arm, because that is to him, his play time. If I ignore him, he just jumps up on me putting his nose right in my face. When I finally get up he gets really excited and jumps up on me then runs to the door whinning away till we go out and toss the frisbee.
The other thing is that he knows when either me or the wife is thinking about going somewhere and he sits and watches us intently. Then when we are about ready, he runs to the door, opens it himself and runs to the car so he gets to go along for the ride.
He also thinks it is his job to wake me each morning, usually just about daylight. He comes to the bed and nuzzles my arm till I scratch him a bit. He has a snooze alarm also, if I tell him it is too early because I want to sleep in a bit, he goes away and comes back in about 10 minutes to repeat.
Once he is sure I am getting up, he leaves and goes back to his bed to sleep till Mom gets up(usually about 830 but sometimes earlier.
He also wont wake Mommy if he wants to go out, instead he comes to me to let him out at night. This is usually because he has smelled / heard a creature roaming outside.
