You need quiet. He needs a job. The KONG Classic is the stuffable rubber toy that gives him one: fill the hollow center, freeze it, and a quick snack becomes a long lick-and-chew.

Who the KONG Classic suits

  • Dogs who need a job and a way to burn off energy indoors.
  • Owners who want one toy to do three things: stuff, freeze, bounce.
  • Any size of dog. It comes in multiple sizes and strengths.

What it does

  • Stuffable: the hollow center takes treats, peanut butter, wet food or a frozen meal.
  • Freezable: a frozen fill turns it into a long lick-and-chew job.
  • Bouncy: an unpredictable bounce keeps fetch interesting, solo or together.
  • Classic: the rubber toy dogs have had for more than 40 years.

Stuff it, freeze it, hand it over.

How to use it

  1. Stuff the hollow center with treats, peanut butter or wet food.
  2. Freeze it so it lasts longer.
  3. Hand it over on a hard floor if the fill is wet.
  4. Wash it after a wet fill. A bottle brush reaches the far end.
