It just happens

Every time our grandson and the dogs get together, I'm amazed. There's no snapping, no hitting, and no inappropriate  behavior by anyone. The dogs seem to know he's a little boy and they are so excited to see him-they run in circles wagging the tails and jump up and down until he pets them. Then, he has to find toys to throw for them. They kiss each other and watch each other sleep. I love watching the dogs stand near him just watching him sleep. They silently sit there wagging their tails until he moves. Some times, there are long periods of time that they don't get to see each other but nothing changes.
