Bobo's getting old. You can see the white hairs encroaching on his blond coat, plus there's a thick streak of white running down between his shoulder blades. Mornings are tough, but by noon he's usually running around like a crazy mutt, the crazy mutt we all know and love. (Guesstimates by the vet put Bobo's age between 8 and 9 years—sixty or so in human time.)
