kong fillers for your dog, dog with kong

I’ll never forget the day my dog trainer at Puppy Kindergarten told me about the kong. 

That she was grooming her german shepherd and he was getting antsy and – BHAM – enter the Kong and some peanut butter and calm calm puppy.


See we have a Newfiedoodle puppy who was supposed to be calm and patient and gentle and guess what? He ain’t. He’s highly energetic, slightly rowdy, and overly confident. 

In other words, he’s me except a dog and male and, well what did I expect?

So, I got the Kong and that was that. But then… whatever to fill it with? Time to whip up some kong stuffing ideas!

Why do you use KONGs with dogs?

You can, of course, simply give your dogs this food. And that’s fine too!

Putting snacks into Kongs is a great thing to do if you are wanting to give your dog a job to do. My trainers said my particular kind of dog (a doodle mix) is smart and needs work. So by stuffing food into the Kong you turn their dog toy into a slight puzzle or challenge.

It extends the amount of time the snack lasts. 

Fill your dog’s Kong toy with whatever tasty treat you desire or have on hand, and let your dog get busy eating. 

It helps you teach your dog to settle because while they’re eating… they’re settled.

Super Popular KONG Fillers

Without further ado… here are some kong fillers your dog will love. 

And a stuffed kong gives your dog something to focus on if you want to teach them. So, for example, if you want to teach your dog to settle. You can put a doggy bed by the couch and, with your puppy on a leash (so they don’t get away), put the Kong on the doggy bed. 

Natural Peanut Butter

This is a no brainer kong filler and dare I say a kong classic. It is likely the first thing you are recommended to put into the Kong. My trainer said if she needed to bathe her dog, she’d slap some peanut butter on the top of the tub.


Most peanut butter is safe as dog treat, and in moderation peanut butter can be an excellent source of protein and healthy fats, vitamins B and E, and niacin. 

The healthiest option is unsalted peanut butter or homemade peanut butter, as high sodium levels can be problematic for dogs, and as an added bonus, homemade peanut butters do not contain extra sugar and other additives. (source)

Cheese Whiz

This isn’t exactly an organic choice for your dog, but as a treat, it’s definitely something your pup will love. It is also, if I’m honest, super fun to squeeze.

What can I say?

This is also something great to take with you while traveling because it doesn’t require refrigeration and you can pull it out in a pinch. 

This is in Moose’s top 2 fave KONG fillers!

Canned Wet Dog Food

dog food kong filler

This is, by far, Moose’s favorite kong stuffing. I bought the Cesar brand canned dog food from Wal-Mart and have had great luck. He went to town on this – and actually contributed to his positive association with the KONG!

Love at first taste.

I definitely do this for Moose on the reg when I need him to calm down and settle, but not so much it disrupts his actual eating schedule.

Dog Kibble

puppy kibble, kong filler

We like to treat Moose because he’s very food and treat motivated and one way to dole out treats that takes a bit longer and requires a bit more work for him is to cut up the treats small enough they go into the KONG but not so small they fall out too easily. 

Our trainers even encouraged us to freeze them, but I’m not that cruel of a dog mom. YET. 

Dairy (Or Dairy Substitute ) KONG Fillers

Cottage Cheese

Start small and make sure yours doesn’t have any intolerance to dairy. Test with smaller amounts and watch for any signs of intestinal upset. (source)

This is also bound to be a fairly messy stuffing so you might want to save this for an outdoor treat or one that puppy has on the tile floor in the kitchen when you need to keep him occupied and not barking. 

Greek Yogurt

cottage cheese kong fillers

Greek yogurt is the safest type of yogurt for your dog to eat as there is no added sugar. It can taste a bit tart, so fill the kong a bit and see if your dog will take it before filling it up too much. (source) Plain yogurt is a great option to avoid any artificial sweetener.

Coconut Whipped Cream

If you want to give your dog a sweet cream treat but are steering clear of dairy, this is a great idea. You’ll get a high quality coconut cream, chill it overnight, then whip it into soft peaks.

Your dog will need to eat it all in one sitting (or spread it among a few dogs if you are a Multi Dog Mama) because it won’t keep, but it’ll be sure to be a fave. 

Here’s how to make coconut whipped cream for dogs.

Nice Cream

Some ice cream – particularly vanilla with no sugar added is said to be the safest – is fine, but too much and we’re into sugar overload territory. 

Enter… nice cream.

It’s essentially dairy free “ice cream” because it has that cold creamy tasty consistency. Your dog will love this, even if they’re lactose intolerant or you’re avoiding dairy with your dog altogether.

Making this is easy. Peel a banana and pop it in the freezer overnight. Put it in your food processor or blender the next day, and viola! We have nice cream for our furry best friend.

Veggie And Fruit KONG Fillers

Here are some veggies and fruit kong stuffing that will thrill your pup. 

Pumpkin Puree

pumpkin puree kong filler

This stuff is so easy to come by, particularly during the fall season, but a can of this will be good for one or two Kong stuffing fills, depending on how long you want to occupy your little one. It’ll also give the crate a lovely scent. 

Sweet Potato Puree

This is similar to pumpkin puree but with, you know, sweet potatoes.

Don’t buy canned yams because those have added sugar which isn’t great for dogs, although a tiny bit likely won’t hurt. If you are cooking sweet potatoes for dinner or roasting them, you can set some aside, mash, and shove into the KONG.

Sweet potatoes are safe for dogs, even those with food allergies (source) and you can even dehydrate sweet potatoes to make some crunchy canine chips. 

Beans, Beans, And More Beans

Don’t serve your doggie canned beans as they are filled with sugar and additives. However… you can serve beans that have been soaked and cooked. If you have extra from your own dinner, that is. 

To avoid a lot of gas, serve beans in moderation, but you can fill the Kong with some COOKED beans (green beans, pinto, garbanzo). Read about the particular type of bean you’d like to serve to be sure. (source)


bananas in bowl in front of kong

Bananas are inexpensive and high in fiber, potassium, vitamins, biotin, and copper. (source). They are a tad messy, but will be a great surprise in the kong for your pup. 

You can mash them a bit with a fork then stick them in. 


blueberries kong fillers, blueberries on counter

Blueberries are a source of rich antioxidants and safe for dogs.

Warning: these will make a mess. If you want to put blueberries into your Kong then you might want to let the dog eat it outside or somewhere you aren’t worried about staining rugs, pillows, or throws. 


Cucumbers can be pulled from your salad, squished up, and put into the KONG as well. This is a light refreshing snack and great if you are worried your dog is overweight.

Some dogs simply become unhealthy in many ways if they are slightly over weight (think hips!) so this is a nice snack you won’t have to feel guilty about. 


carrots in dog bowl on counter

Carrots that are hard are a great thing for teething puppies, but you can also cook the carrots or give the dog leftovers from dinner, mashed a bit. 


I don’t know who DOES NOT love watermelon.

Personally, we eat it with some salt to bring out the flavor, but I wouldn’t recommend that for the dog. Cut the watermelon into small ish pieces, mash them a little, and put them into the Kong. Great for a hot summer’s day!

KONG Recipes

All the foods above are single ingredient KONG fillers and stuffers. They will go straight in the KONG. Here are some kong stuffing recipes or combinations of food that dogs love that you can put into the KONG.

Sometimes you can shove what you cooked for dinner in your KONG, but be sure you aren’t serving your pup foods that are toxic to dogs.

  1. Pumpkin and sweet potato. You can mash them up or put the purees in, either way this is a healthy treat.
  2. Applesauce and oatmeal. You can freeze this so it doesn’t leak out, but this is a great and filling combination kong recipe.
  3. Blueberries and bananas. A popular combination in desserts. Mash up the banana and blueberries together until they’re more of a paste.
  4. Cauliflower and broccoli. If you have these leftover from dinner, blend them together until they are more of a soup and put it into a KONG
  5. Steak and rice. Yes, meat also works as a kong filler and has that uniquely irresistible flavor! This is a great way to use your leftover meat. If you’ve got some left over from dinner, drop them into a KONG instead of dropping them on the floor.
  6. Pineapple and strawberries. For a sweet fresh summer treat, put these into the KONG mashed or not!

You can also put essentially any combination of the fillers from above together into a KONG too.

Remember, a good rule of thumb for any kong recipe, if in doubt… ask your vet whether a certain food will be harmful to a dog. These KONGs will keep dogs busy for a long time and are a good crate companion.

How To Clean KONGs After They’ve Been Filled

  • KONGs are dishwasher safe, and you can put them on the top rack.
  • You can rinse with warm water and dish soap. 
  • If there is dried food inside that won’t come off easily, you can also use a bottle brush to get it clean.

  • 1/2 cup sweet potato puree
  • 1/2 cup beans (not canned) but soaked and cooked

  • Choose one ingredient from above (or mix if you want to get creative) and stuff it into the KONG.


  • Don’t stuff it down too packed or pup will have a hard time getting out the food at the bottom and it’ll be more difficult to clean.

  1. We freeze our kongs all of the time for our lab. She LOVES them frozen. Good, new ideas here! We do pumpkin and bananas regularly.

    • Yes!!! And I find our newfiedoodle is actually quite bright, smarter than I am I think as I’m not great thus far at training and our Puppy Kindergarten teachers said freezing the things gives them more “work” so it actually is both physical nourishment and some physical work. 🙂

    • Where could I purchase one of these Kongs?

  2. Fill and freeze for a treat that lasts a long time.

  3. I liked your ideas for the long. I’m going to try your ideas.

  4. Rachel, these Kong ideas are awesome! Can’t wait to try them on my dogs, who LOVE their Kong’s! Thanks for the great ideas!

  5. This blog KONG Fillers: 15+ Foods Your Dog Will Totally Love has helped me a lot with
    my dog.

  6. We use grated carrot, natural peanut butter, and crushed up dog cookies mixed together. You can freeze or give right away. Stays in the Kong well too. Thanks for your ideas.

    Hi! Dog trainer here! Just wanted to make a note of something… You wrote, “You can put something like peanut butter at the bottom of the KONG to make a seal.” I would caution you and your readers against this advice. The hole in the bottom of the Kong is there to prevent the tongue from getting sectioned inside the toy and stuck (causing seriousinjury). It helps maintain airflow and prevents airlock.

    I have two poochoonsThat are eight months old and I got them the Kong’s……Who’s willing to clean up the mess

  9. Claire Lind

    I have two large dogs. I tried to use the king to keep them busy. I stuffed it with peanut butter a bananas and froze them. My dogs had a hard time getting the frozen stuff out of the king. The frozen peanut butter mixture went into the middle and couldn’t lick it out get it out. They were very frustrated. Please help with any ideas. Thank you!

    • Rachel Norman

      HI Claire, so if it’s summertime and things will deforst more quickly then you can put them outside and let them melt a tad bit. That would still give the dog “work” to do but without it being so frozen it’s frustrating. I found that the stuff at the very back of the KONG also gets a bit stuck so I simply filled the to part they could more easily access!

  10. I have been doing the peanut butter, but this gives me some great new ideas. An idea for the lady for the lady that has a problem with it being froze in the middle. I use a butter knife and put it on the inside the wall of
    the Konga and I don’t put it in the middle when I fill it. Hope that is helpful.

  11. I put some pnb in the bottom of the Kong and fill it with chicken broth and blueberries then freeze. What a treat. I vary the ingredients with carrots, snap peas, pears, apples.

  12. I’m trying to give my pup something to keep her busy while in her crate. Won’t theses fillings get messy? Are there any in particular that you don’t think will cause me to have to wash her crate pad every night?

    • Rachel Norman

      Hi Kristin yes they will get messy! 🙂 Sometimes our dog ate them so thoroughly there wasn’t a big mess, but it depends on your mess tolerance, I suppose!

  13. 5 stars
    Hi! I have a 10 mo old Cane Corso and have used the Kong for her “night-night” time. I have always frozen them. Doesn’t seem to leave a mess. She is crate trained. I have only used the wet dog food but will be using some of your ideas. What size Kong do you use?

  14. 5 stars
    These are very easy and my pitbulls love them i had to mix a little bit of dog food with the carrots because they eat carrots in their food but not alone but all and all 5 stars.

  15. I buy the very lean ground beef, and roll into freeze 1 TBSP size balls. Freeze. Pop 2 into the large Kong and yummy frozen treat that calms my hyper boxer.

  16. 4 stars
    Thank you for you amazing ideas. How do you choose the correct size of the Kong. I have an English bulldog 1 1/2 years old 50lb and a 4month old 19lb
    Thank you

    • I’d suggest you refer to the information from KONG or ask your local vet, but a bigger dog will likely want a bigger KONG.

  17. Question how do you do the applesauce and oatmeal and and certain oatmeal? Apple sauce be unsweetened right. I have a lot of oatmeal. I own a Siberian Husky he’s 5 thank you

    • Overall, dogs can eat applesauce without any issues. However, most brands are filled with extra sugar and other artificial ingredients. Look for an organic brand that doesn’t add extra sugar or use unsweetened applesauce. As far as oatmeal, you might want to research which kinds are best and how they should be prepared. I found this information online but you might also ask your local vet for suggestions. “Stay away from instant oatmeal. While it’s faster and easier to prepare, it’s highly processed, and the health benefits your dog gets from eating oats will decrease. Don’t give your dog too much oatmeal at once because it contains a lot of carbohydrates and is relatively high in calories.”

    • Baby food is also an easy alternative! I do baby food and throw in some dehydrated chicken hearts and she LOVES it! Or baby food and ground turkey/chicken and freeze it just enough to get the baby food from sliding

  18. Please be careful when suggesting peanut butter many brands contain xylitol which is toxic to dogs.
