Kai stares intently at the front of the car.
His mouth salivates with anticipation. His eyes are fixed and focused, ears taut and high.
Suddenly, from behind his head flies a 6-inch piece of fire hose.
He snatches it up and sends it soaring above him. His tail wags uninhibited as he rolls on the ground, enjoying his moment of pure bliss.
The 5-year-old puppy is back.
