My Dog is a child

So I'm ready to go to bed for the night, let the dog in and begin turning everything off and brushing my teeth. Riku (ree-ku) starts whining and whimpering like he needs to go back out and go to the bathroom, but a lot worse than normal, seemed really freaked out. I was pretty concerned so I turned the outside light on and 'checked things out'. I let him out the door, he runs about 5 feet out the door, picks up this new toy that a neighbor bought him yesterday and walks back in. What a retard!
