We just got a new puppy.  My older dog knew to let that one out first when I get home from work.

That is very cute, the little one probably couldn't hold its bladder as long.

Definitely not.  I was surprised that he knew to let the little one go first!

That was very smart of him, maybe he remembers back to his puppy days.
