I am sitting at a restuarant with my family including Angelo who is 5 and he is sitting politely at the table. The next table over the child is running around the restaurant creating nonsense. Angelo must be tired? that is why he is sitting quietly and the other child has not had enough exercise yet that day?

Lets stop making the silly excuse that our dog needs more exercise in order to behave, there is a much simpler answer actually to why dogs behave and why children behave.
