Get Stuffed! Over 50 Ways to Fill Your Kong


Need more ideas to fill your dog’s KONG toy with? Looking for a way to save money with low-cost ingredients that you probably already have? Interested in a way to keep your dog busy with his KONG for longer than 5 minutes? BARKTASTIC! Let BarkThink show you the best way to stuff your KONG toys to maximize your dog’s chewing experience that will increase his mental stimulation and keep him busy longer. This KONG stuffing technique can be particularly effective in calming dogs with anxiety, tiring down hyperactive dogs, soothing fearful puppies, and crate training.

KONG Dog Toys, and similar treat-dispensing toys, has always been a MUST-HAVE toy for my sanity and my dogs. These wonderful enrichment toys is readily available at most pet stores or online.

The premise is simple: stuff the toy with food and allow your dog to keep themselves occupied while he/she works at obtaining the food inside.

What about destructive chewers? Fortunately, KONGs are made out of long-lasting, durable rubber and is built to withstand a dog’s biting. There are also several variations for puppies, older dogs, and extreme chewers.

Dog owners often fill their KONG with treats and kibble in hopes of keeping their canine companion occupied for the hours claimed on the product packaging. Unfortunately, in reality, this usually does not happen quite as advertised. Often, the dog will quickly empty out the kibble-filled toy and quickly become bored once they have achieved their goal of eating the treats. Food paste and peanut butter lasts a bit longer; but still, can be consumed within 5-15 minutes. However, when packed appropriately, these food-stuffed toys can last for an hour or more in keeping your dog occupied, mentally stimulated, and satisfied (and getting rewarded with delicious goodies, of course!).

In my years of trying to keep mischievous puppies occupied and away from things such as furniture, I discovered some effective and healthy ways to get the most out of the KONGs. Ready to learn the secret?

Here’s my million dollar tip to get the most out of your KONG:
Use Layers & Freeze it.

Freezing Your Kong Dog Toy

Basically, you stuff the KONG Dog Toy in multiple layers of food, and then freeze it. By freezing the ingredients, it will last much longer and provide more stimulation for your canine companion. Sure, you can use the expensive fillers sold at the pet store…but have you looked at the ingredient list? It may be convenient; but not so healthy for long-term use. You can easily blend a healthier mix from a variety of leftover foods you already have in addition to their regular dog food or treats.

Freezing Kong toys can also save you time! By having more than one Kong toy, you can freeze several ahead of time until you actually need them. I’ve had friends who had at least 7 Kongs for their dogs—one for each day of the week. Often, their dog would instinctively run into their kennel whenever a Kong is pulled out of the freezer!

Keep in mind: The ingredients you use to stuff your dog’s Kong will add extra calories, in addition to their regular food. Therefore, to avoid overfeeding, you should adjust their rations accordingly at regular meal times.

Here is an illustration using a popular 4-layer method for stuffing your KONG. Be creative and change up the ingredients as you (or your puppy) please!

Mix It Up! Change is Good

Like dog toys, it is always a good idea to ‘mix it up’ in order to help prevent your dog from getting bored with the same thing.

With KONG Dog Toys, alternating between freezing and not freezing the fillings works well, as does changing up the ingredients stuffed inside the KONG.

For a change of pace, instead of using a KONG, you can try stuffing a hollowed out marrow bone (available from your local butcher). The key is to ensure that bone length is two to three times the length of your dog’s tongue.

Alternatively, popular KONG alternatives in our home has been the PetSafe Busy Buddy Squirrel Dude Dog Toy and PetSafe Busy Buddy Barnacle Dog Toy.

2017 Update: Lately, in addition to the KONG, the Nylabone Dura Chew Marrow Alternatives have been a HOWLING hit with our dogs. Both, our small Rat Terrier (Spock) and Olde English Bulldogge (Otis) have been stealing each others bones and eating it for themselves. You can stuff it similar to the way you stuff a KONG; but it feels and looks like a hollow marrow bone. Otis, our most aggressive chewer, has enjoyed the ability to gnaw on it like he does traditional nylabones…a two for one winner!

How to Clean & Sanitize KONG Dog Toys

    While I’m sure the dogs would love all of those messy treats, I don’t feel like cleaning up what’s been smeared all over the floor and rugs. I guess I’ll stick to dry treats.

    • Maria Myrback on

      Sure, you might get a few bits of kibble on the floor, but as a general rule, frozen kongs stay together really well.

    • Kathy graham on

      I use peanut butter and stick a couple of small treats inside, freeze it Nothing on the outside. Never have had a mess at all

    • I’ve never had a mess from frozen Kongs. Our puppy always gets one in her crate, whether when we are leaving for work or at bedtime, but there is zero mess in the crate as she licks it frozen. It works so wonderfully and she now LOVES her crate since she associates it with this special treat! So for any new puppy owners, freeze the Kong and you will have zero mess!

    • My dog goes to her cage with hers and she cleans up her own mess. It keeps her occupied and entertained. And it also works her jaws so she doesn’t chew on MY things. But then again I have a very active and very aggressive chewer so I guess it all depends on your dog.

  2. A note on nuts: while peanuts, cashews, and hazelnuts are great for dogs, almonds, walnuts, macadamia nuts, pecans, pistachios, and hickory nuts are doggy no-nos. Some nuts only give dogs an upset tummy but some can cause seizures and pancreatitis.

  3. Hot dogs? Pizza crust? Peanut Butter? **I frown upon – especially lately (maybe a pinch, here and there) but NOT often

  4. Erika garza on

    Thanks for the post. I was looking for recipes for my two new large kongs. I love them for my two huskies. I also really liked the like for the squirrel one I bought two on Amazon.

  5. Can you use the kong balls? The holes seem kinda small but I didn’t think about it till after I left the store with it.

    • Hi Stacy!

      Are you referring to the (mostly) solid rubber KONG balls with the hole on each end such as these? KONG Ball with Hole

      If so, yes you can…but it’s a bit tricky to fill and clean because it has TWO large openings in it versus 1 small and 1 large in a traditional KONG. I would recommend using something with a bit more substance/thicker to seal the hole. My go-to is often peanut butter or similar consistency.

      Alternatively, my favorite KONG ball is the KONG Stuff-a-Ball because of the options available with the ridges. Albeit, I’ll admit it usually don’t entertain as long as a regular KONG though. But definitely provides great variety for the pups! Let me know if you have any other questions.

      Thank you!

    Please be extra careful when giving frozen treats to dogs! On hot days this can actually cause them to over heat. Their self cooling system works differently than in humans. If they eat ice and other frozen items it can make their system think they are cold and trigger their bodies to “warm up” even if they are already hot.

  7. I use their regular food stirred up with peanut butter just lightly coated) and layered with sliced frozen banana and apple cubes.
