Quincy, Luther's Dog: Great Character Actor

In my most recent A-Z List, I've been exploring characters that change. 

One of the funniest non-human examples is Luther's dog Quincy. 

Quincy is a basset hound. As the guy at the pound says, "A ficus tree and basset hound are pretty much the same thing." 

Except--

Quincy will go crazy when he is left alone or when he sees certain people/colors. So, he destroys the band room and later attacks the band director. 

The hilarity of these moments is how entirely sleepy and unaffected Quincy looks when he appears on-screen--as compared to what people hear him doing or hear about him doing. 

Rather touchingly, Quincy also changes in terms of getting older and eventually dying. That is, he lives a full pet life with Luther, who is equally impacted by Quincy. Eventually, Luther ends up with a new "little" Quincy.
