1. Start with an empty cardboard paper towel or toilet paper roll. Fold the ends of one side of the tube to seal that end shut. You can also reuse an empty cardboard box instead, but be sure that it can still be closed properly.

2. In a bowl, mix together peanut butter or pumpkin, your dog’s dry food and a handful of other treats like crunchy veggies or cheese bites.

3. Carefully fill the tube or box with the dry food mixture through the open side and then close the ends to seal the tube completely (for tubes fold the open end in). For extra flavor, leave it overnight in the freezer to let the cardboard absorb the peanut butter or pumpkin flavor and smell!

4. Your treat tube or Busy Box is now ready! Find a dog to give it to and watch them enjoy!
