Sparkey has always been well-known for his retention of that most puppyish and endearing habit---the head-tilt-while-listening. The photo at left illustrates a classic example of such, circa May, 2005.
He would always reliably tilt his head from side to side in response to his favorite questions said with a marked questioning uplift at the end, obviously trying to divine the meaning of our question and the authenticity of the offer:
Do you want to go for a walk outside?
Do you want a treat?
Do you want to go for a ride in the car?
Do you want me to dial the number for you?
Alas, the head-tilt is a phenomenon of the past, but his cuteness is not diminished. Au countraire! He is more endearing by the day.
