The karaoke version of “Hound Dog” builds to a rollicking crescendo. Elvis has the packed house in the Community room at Heritage Ridge Senior Living collectively nestled in the palm of his outstretched hand.

Well, you ain’t never caught a rabbit
And you ain’t no friend of mine

Suddenly, 2nd Floor Bob rolls in on his scooter. Mavis, a real-life hound dog, spots him. Her ears perk up and she goes rigid. She strains on her leash-pulling to get to him. Mavis knows 2nd floor Bob always packs a satchel full of king-sized treats which he doles out to her like a doting grandparent.

Elvis delivers the last verse in a frenzied flourish.

You ain’t nothin’ but a hound dog!

On cue, Mavis eyeballs Bob and begins to bark. The crowd erupts.

Elvis is visibly flummoxed. It’s obvious he wasn’t aware there was an actual dog in his midst.

I lift the culprit to reveal her to him. Elvis laughs and says, “What’s her name?” I say, “Mavis.” He replies, “I’m glad it’s not Priscilla!”
