A stuffed Kong is one of the easiest ways to keep a dog busy, calm, and happy. Licking and chewing are natural, soothing behaviors for dogs. A well-stuffed Kong turns them into a puzzle that can last anywhere from ten minutes to an hour. It also helps with boredom, crate training, and separation stress.
Most people stop at peanut butter. These five recipes use simple, dog-safe ingredients you probably already have at home, and they work for beginners and clever chewers alike.
Why Stuffed Kongs Work So Well
Kongs do more than fill time. Here is what they offer:
- Mental stimulation: Working food out of a toy engages your dog’s brain.
- Calming effect: Licking releases endorphins, which can help anxious dogs relax.
- Healthy chewing outlet: It redirects chewing away from shoes and furniture.
- Slower eating: It’s useful for dogs that gulp their food.
What You Need Before You Start
- A Kong toy in the right size (a toy that is too small is easy to empty and can be a choking hazard)
- Your dog’s regular kibble or a few small treats
- A mug or tall glass to hold the Kong upright while you fill it
- A freezer, for the longer-lasting recipes
Tip: Plug the small hole at the bottom with a dab of peanut butter or a piece of soft treat. This keeps the filling from falling out and makes your dog work longer.
Recipe 1: Classic Peanut Butter and Banana
This is the all-time favorite, and it’s hard to beat.
Ingredients:
- 2 tablespoons xylitol-free peanut butter
- ½ mashed ripe banana
- 2 tablespoons of your dog’s kibble
How to make it: Mix the peanut butter and banana, stir in the kibble, and spoon it into the Kong. Freeze for at least four hours for a longer-lasting treat. If you want to bake something similar for the jar, try these peanut butter banana dog treats.
Important: Always check the label for xylitol. It is extremely toxic to dogs, even in small amounts.
Recipe 2: Pumpkin and Yogurt Swirl
This one is gentle on the stomach and works well for dogs with digestive sensitivities.
Ingredients:
- 2 tablespoons plain canned pumpkin (not pie filling)
- 2 tablespoons plain, unsweetened yogurt (skip it if your dog is dairy-sensitive)
- A small handful of kibble
How to make it: Layer the pumpkin, yogurt, and kibble into the Kong, then freeze overnight. Pumpkin is high in fiber and has a mild, sweet flavor most dogs love. For more ideas using this ingredient, see our guide to pumpkin dog treats.
Recipe 3: Chicken and Sweet Potato Mash
A savory option for dogs that prefer meat over fruit.
Ingredients:
- 2 tablespoons plain cooked chicken, shredded
- 2 tablespoons mashed cooked sweet potato
- 1 tablespoon low-sodium chicken broth (no onion or garlic)
How to make it: Mix everything into a thick paste and pack it into the Kong. Freeze for several hours. Make sure the chicken is fully cooked, plain, boneless, and free of seasoning.
Recipe 4: Apple and Blueberry Freezer Stuffer
A refreshing, lighter option that’s especially nice in warm weather.
Ingredients:
- 2 tablespoons unsweetened applesauce
- 1 tablespoon blueberries, lightly mashed
- 1 tablespoon plain yogurt or water
How to make it: Stir the ingredients together, fill the Kong, and freeze. Blueberries are rich in antioxidants and add natural sweetness. Be sure the applesauce has no added sugar.
Recipe 5: Beginner’s Kibble Kong
If your dog has never used a Kong, start easy.
Ingredients:
- Your dog’s regular kibble
- 2 to 3 tablespoons of warm water or low-sodium broth
How to make it: Soak the kibble for about ten minutes until it softens, then pack it into the Kong. Don’t freeze this one at first. Let your dog learn that food comes out of the toy before you add difficulty.
How to Make Kongs Last Longer
Once your dog gets good at emptying them, raise the challenge gradually:
- Freeze the filling for a slower lick.
- Layer ingredients, with soft food at the bottom and bigger pieces near the top.
- Use a thicker filling such as mashed sweet potato or peanut butter.
- Stand the Kong in a freezer bag so it stays upright and doesn’t leak.

Foods to Never Put in a Kong
Some common human foods are dangerous for dogs. Never use:
- Xylitol (found in some peanut butters and sugar-free products)
- Grapes and raisins
- Chocolate
- Onions and garlic
- Macadamia nuts
- Heavily salted or seasoned foods
If you’re unsure about an ingredient, ask your veterinarian before using it.
Portion and Calorie Tips
Stuffed Kongs are treats, so count them toward your dog’s daily calories. As a general guideline, treats should make up no more than 10% of daily intake. If your dog gets a Kong every day, reduce their regular meals slightly or use part of their kibble as the filling. Always supervise your dog the first few times, and replace the Kong if it becomes cracked or damaged.
Frequently Asked Questions
How often can I give my dog a stuffed Kong?
Once a day is fine for most dogs, as long as you adjust their meals to account for the extra calories.
How do I clean a Kong?
Rinse it with warm soapy water and use a bottle brush for the inside. Many Kongs are also dishwasher safe, so check the packaging.
What size Kong should I buy?
Choose a size appropriate to your dog’s weight and chewing strength. When in doubt, ask at your pet store or check the manufacturer’s size chart.
Can puppies have stuffed Kongs?
Yes, with softer fillings and a puppy-specific Kong. Supervise them and keep portions small.
Final Thoughts
A stuffed Kong is an inexpensive, effective way to keep your dog entertained and calm. Start with a simple recipe, watch what your dog loves, and experiment from there. With a bit of creativity, you can make every Kong a little different and keep things exciting.
