Use your dog’s regular kibble, a few small dry treats, pâté-texture canned dog food, plain canned pumpkin, or yogurt your dog tolerates. You can also combine suitable ingredients such as cooked chicken, carrot, fruit purée, or broth in a frozen filling. The right choice depends on your dog’s allergies and digestive tolerance, calorie plan, chewing habits, and whether you want easy licking, a puzzle of loose pieces, or a longer-lasting frozen challenge.
There is no universally best peanut-butter substitute. VCA Animal Hospitals and the American Kennel Club both emphasize matching ingredients and texture to the individual dog and the toy. Start with a small amount, count edible filling as part of the day’s food or treats, and supervise the first sessions.

Quick comparison: what can replace peanut butter?
| Filler | Best use | Important qualification |
|---|---|---|
| Regular kibble or part of the dog’s meal | Everyday enrichment without adding a separate treat | Remove the amount from the normal meal plan rather than adding unplanned calories. AKC and VCA both describe a dog’s meal or small dry kibble as a toy filling. |
| Small dry treats or biscuits | A toy that releases pieces as the dog rolls or manipulates it | Use pieces that fit the opening and suit the dog’s size; no universal portion is established. |
| Pâté-texture canned dog food | A soft, spreadable filling for licking | Choose food appropriate for the dog’s diet and follow veterinary advice for medical conditions. |
| Plain canned pumpkin | A soft, moist filler or an ingredient in a frozen mixture | Check the label and use an appropriate plain product; not every pumpkin preparation is suitable for dogs. |
| Plain yogurt | A soft filling or frozen enrichment for dogs that tolerate dairy | Dairy tolerance varies. AKC notes that plain yogurt may be easier for some dogs to tolerate, but it is not suitable for every dog. |
| Cooked chicken, carrot, fruit purée, or broth | Recipe-style frozen fillings | These are examples from AKC frozen-treat guidance, not a complete diet. Check every ingredient and your dog’s tolerance. |
| Commercial paste-like filler | When you want peanut-butter-like stickiness | VCA names KONG Stuffin as an example, but its current ingredients and availability should be checked on the package before use. |
VCA’s enrichment guidance is available at VCA Animal Hospitals. AKC’s indoor-enrichment ideas are at the American Kennel Club.
Choose the filler by texture and the activity you want
For simple licking
Soft foods create a licking activity rather than a scavenger hunt. Pâté-style canned food, plain pumpkin, or tolerated yogurt can be pressed into the cavity. A sticky or smooth food also helps hold a few dry pieces in place, acting as an edible “glue.” This is useful when a dog quickly empties a toy filled only with loose kibble.
For rolling, shaking, and problem-solving
Use the dog’s kibble, tiny dry treats, or a mixture of both when you want pieces to move and fall out. VCA specifically lists small dry kibble and tiny pieces of dry treats for building a more involved activity toy. The toy’s opening must be large enough for pieces to escape but not so large that everything falls out immediately.

For a longer session
Freeze a filled toy after checking that the toy and food are suitable for freezing. AKC describes filling a favorite chew toy with a recipe and freezing it. Frozen food generally takes longer to lick out than the same food at room temperature, but the duration will vary with the dog, the toy, and the amount used.
How to stuff a dog toy without peanut butter
- Inspect the toy first. Use a food-stuffable toy designed for the dog’s size and chewing behavior. Discard it if it is cracked, split, or shedding pieces.
- Pick one familiar ingredient. Start with the dog’s regular kibble or a food the dog has already eaten safely. Introducing several new ingredients at once makes it harder to identify the cause of a digestive reaction.
- Decide whether the filling replaces food. If you use kibble or part of a meal, measure that amount out of the dog’s regular ration. If you use treats or richer food, account for it in the day’s calorie plan.
- Load the toy in layers. Put a few loose pieces at the bottom, add a soft food if you want them held in place, and finish with more dry pieces or a soft layer. Do not force food into a cavity so tightly that the dog cannot reach it.
- Adjust the difficulty. A larger opening and loose kibble make an easier beginner puzzle. A soft filling, mixed textures, or a frozen toy increases the licking and manipulation required.
- Chill or freeze only when appropriate. Place the filled toy in the refrigerator or freezer on a clean surface if you want a firmer challenge. Follow the food’s storage directions and do not leave perishable filling at room temperature longer than recommended.
- Supervise the first attempts. Watch how the dog chews, whether the toy releases food, and whether the dog tries to destroy the toy. VCA advises initial supervision.
- Remove and clean it after use. Take away the toy when the food is gone or the session ends. Wash it according to the manufacturer’s instructions and let it dry fully.
The best alternatives, explained
1. Your dog’s normal kibble or meal
Kibble is the simplest substitute because it is already part of the dog’s diet. Measure a portion of the normal meal into the toy, or use the entire meal if the toy and the dog’s eating pace make that practical. This turns feeding into enrichment without automatically adding a separate treat.
Recommended Free Tools
Dry food works best when the toy can release pieces through movement. If it spills out too quickly, mix some kibble with a small amount of a tolerated soft food or choose a toy with a more challenging opening. The key calorie rule is accounting: food placed in the toy still counts as food eaten.
2. Small dry treats or biscuits
Tiny dry treats provide a stronger smell and a more varied reward than plain kibble. VCA lists small pieces of dry treats as a way to make an activity toy more involved. Break large treats into pieces that cannot become wedged dangerously and that fit the toy’s opening.
There is no source-supported universal number of pieces. Use the smallest amount that creates the desired activity, especially for a dog on a weight-management diet. If the dog receives other treats that day, reduce the toy portion accordingly.
3. Pâté-texture canned dog food
VCA identifies pâté-texture canned pet food as a straightforward store-bought filling. Its smooth consistency is easy to spread inside a cavity and encourages licking. You can use it alone or press a few kibble pieces into it for mixed texture.

Select a canned food that fits the dog’s existing diet. A dog with a prescription diet, food allergy, pancreatitis history, or another health condition may need a veterinarian-approved ingredient list rather than an improvised filler. Refrigerate opened food according to its label and wash the toy promptly.
4. Plain canned pumpkin
AKC lists canned pumpkin among tasty fillings for a food-stuffable toy. Pumpkin can provide a soft, moist texture and can be combined with kibble or used in a frozen mixture.
Read the ingredient panel. The evidence supports pumpkin as an option, not every pumpkin product sold in a grocery aisle. Avoid assuming that pie filling, sweetened products, or products containing added spices are interchangeable with a plain preparation. If your dog has a condition affected by fiber or diet changes, ask your veterinarian before using it.
5. Yogurt when your dog tolerates dairy
AKC includes yogurt as a toy filler and notes in its frozen-treat guidance that plain yogurt may be easier for some dogs to tolerate than other dairy. That is a conditional option, not a guarantee: dogs vary in their ability to digest lactose and dairy fat.

6. Cooked chicken, carrot, fruit purée, or broth
AKC’s frozen-treat article gives cooked chicken, carrot, puréed banana or melon, yogurt, and broth as examples that can be combined in a favorite chew toy and frozen. These ingredients let you vary flavor and texture without relying on a nut-based paste.

Treat these combinations as enrichment recipes, not balanced meals. Use only ingredients you know are safe for your dog, avoid seasoning and unsafe foods, and check the ingredient list of any prepared broth. A dog with allergies or a veterinary diet should receive only ingredients approved for that diet.
7. Commercial paste-like fillers
VCA mentions KONG Stuffin as a commercial product with a cheese- or peanut-butter-like consistency. A paste can be convenient when you want a spreadable filling that holds dry pieces in place.

How to match the filling to your dog
Dietary sensitivities and medical needs
VCA’s central warning is: “Be sure the ingredients are safe, taking into account your pet’s own dietary sensitivities.” The same page advises discussing safe ingredients and calorie intake with a veterinarian in light of the pet’s size and activity level.
For a dog with a known allergy, chronic gastrointestinal disease, obesity, diabetes, pancreatitis, or a prescription diet, the safest filler may simply be the approved regular food. Do not treat a toy recipe as a way to bypass a veterinary feeding plan.
Calories and treat limits
AKC’s peanut-butter guidance says treats generally should make up no more than 10 percent of a dog’s diet. That 10 percent figure is a general treat guideline, not a recipe measurement and not a toy-stuffing-specific limit. It does not tell you how much pumpkin, yogurt, canned food, or paste belongs in one toy.
Rank #4
- Perfect for stuffing with KONG treats
- Unpredictable bounce for games of fetch
- Recommended Worldwide by veterinarians, trainers and dog enthusiasts
- Made in the USA
- Available in six sizes: XS, s, M, L, XL and XXL
Use the dog’s body condition, normal meals, activity, and veterinary advice to decide how much edible enrichment fits. A toy can make a small amount of food last longer, but it does not make extra calories disappear.
Age, size, and chewing style
A puppy, senior dog, brachycephalic dog, or dog with dental disease may need a softer texture or a simpler opening. A powerful chewer may destroy a toy that is appropriate for a gentle chewer. Preventive Vet’s guidance stresses matching toy size and construction to the dog’s size and chewing behavior.
VCA says a product is not recommended for a pet that chews pieces off it. If your dog removes fragments, stop using that toy and choose a more suitable, durable design under supervision.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Safety checks before every stuffed-toy session
- Inspect the food. Confirm that every ingredient is compatible with the dog’s diet and sensitivities.
- Inspect the toy. Look for tears, missing chunks, sharp edges, or openings that could trap the dog’s jaw or tongue.
- Use the right size. The toy should not be small enough to swallow and should suit the dog’s mouth and chewing force.
- Supervise new combinations. Watch for frantic chewing, gagging, vomiting, diarrhea, itching, or attempts to break the toy.
- Keep hygiene in mind. Wet food, pumpkin, yogurt, chicken, and broth are perishable. Remove leftovers and clean the toy after use.
- Account for the whole diet. A stuffed toy is part of feeding, not an addition outside the feeding plan.
If you still use peanut butter
Peanut butter is not required for a food-stuffable toy, but if you choose it, read the label every time. AKC warns that xylitol is toxic to dogs and recommends checking labels. Use peanut butter only in moderation and treat it as part of the dog’s overall treat intake.

Practical combinations to try
Low-change daily meal toy
Use a measured portion of the dog’s regular kibble. Add no new ingredient. This is the clearest starting point for a dog with dietary restrictions or a sensitive stomach.

Mixed-texture beginner toy
Place a few kibble pieces inside, press a small amount of the dog’s usual pâté-style canned food around them, and leave some pieces near the opening. The loose pieces provide an immediate reward while the soft layer introduces licking.
Frozen enrichment toy
Combine an ingredient your dog already tolerates, such as plain pumpkin, plain yogurt, canned dog food, broth, or a suitable recipe ingredient, with a few dry pieces. Fill the toy loosely, freeze it, and supervise the first session to confirm that the dog can eat it safely.

Use tiny dry treats or broken biscuits with kibble. Choose a toy that lets pieces fall out as the dog rolls it, and reduce the rest of the day’s treats to keep the calorie plan intact.
Troubleshooting common problems
The toy empties immediately
Use a smaller opening, add a soft layer to hold pieces, or freeze a suitable filling. Increase difficulty gradually rather than packing the cavity so tightly that the dog becomes frustrated.
The dog ignores the toy
Start with the dog’s familiar meal and leave some food visible near the opening. A new toy, unfamiliar smell, or difficult opening can all reduce interest. Make the first session easy, then increase the challenge.
The dog tries to destroy the toy
End the session and inspect for damage. A dog that chews pieces off should not continue using that product; VCA specifically advises against it. Choose a size and construction suited to the dog’s chewing behavior and supervise.
