Game #11 · Brain & Foraging

The Shell Game

Boosts focus and relies heavily on scent discrimination.

What you need:
Three plastic, non-see-through cups and a highly aromatic treat.

How to play

  1. Let your dog watch you put a treat under one cup.
  2. Tell them to find it, and lift the cup when they point or paw at it.
  3. Slowly start moving the cups around slightly to mix them up.
  4. Let them use their nose to detect which cup holds the hidden treat.

Coach's notes

  • Start with 2 cups; add the third only once they're 5-for-5.
  • Keep your eyes neutral — dogs will read your gaze before their nose.
  • If they fail twice in a row, drop back a level.
  • This is a version of the exact Two Cups task used in Dognition's assessment.

If your dog loses interest

Quick fixes when engagement drops mid-session.

  • Wrong cup every time? Slow down and let them watch you place the treat with the cup lifted higher.
  • If they lose focus, start with 2 cups instead of 3 for a few rounds.
  • Some dogs paw all cups — reward the first-cup indication with a jackpot to shape a single choice.

Why it works

The Two Cups paradigm is a validated laboratory measure of communication and memory — the same one Dr. Hare pioneered at Duke.
