Developed at the Massachusetts Institute of Obedience Training, DOGO
heralds a new era of computer-literate pets. DOGO commands include SIT,
STAY, HEEL, and ROLL OVER. An innovative feature of DOGO is "puppy
graphics", a small cocker spaniel that occasionally leaves a deposit as
he travels across the screen.
