The Muffin Tin Puzzle

Teaches problem-solving and uses scent tracking.

What you need:
Grab a 12-cup muffin tin, 12 tennis balls, and smelly treats.

How to play

  1. Drop a small treat into a few of the muffin cups.
  2. Cover all 12 cups with tennis balls, hiding the treats.
  3. Place the tin on the floor.
  4. Encourage your dog to sniff out and remove the balls.

Coach's notes

  • Start with treats under only 3–4 cups so the first success comes fast.
  • Add more baited cups every session as your dog builds confidence.
  • If your dog dumps the whole tin, hold it steady with a foot the first few reps.
  • Two 5-minute sessions a day is plenty — sniff work is deceptively tiring.

If your dog loses interest

Quick fixes when engagement drops mid-session.

  • Losing interest? Upgrade to a smellier reward (small piece of chicken or cheese) and bait every cup for one round.
  • If they walk away, cover only 2 cups next time — you rebuilt success too slowly.
  • Some dogs paw instead of nose — reward whichever strategy uncovers the treat first.

Why it works

Scent-led foraging measurably lowers arousal and gives dogs the same kind of cognitive workout Horowitz documents in her Barnard scent-lab studies.
