Locked out

Lately Hayden seems to think the doggy door is his own personal entrance into, and out of the house.  

The other day we came home and found we were locked out of the house.  

Hayden gladly slipped through the doggy door and went and pushed the garage door button to let us in the house.  

He was rewarded with lots of kisses and some candy for saving the day. =)

Initially we put the high chair to discourage him from this behavior, 
and to keep him from letting the cat out at will as well.
Talk about an obstacle course!
