Tips For Filling A KONG Toy

Layering ingredients makes your dog's KONG more challenging and keeps them engaged for longer.

For the best results:

  • Seal the small end with a little peanut butter or yoghurt.
  • Add larger ingredients first.
  • Fill gaps with kibble or smaller treats.
  • Finish with a soft layer of yoghurt, pumpkin or wet food.
  • Freeze for several hours before serving.

Starting with easier fillings and gradually increasing the difficulty helps prevent frustration while encouraging confidence and problem-solving.
