6 Dog Food Filling Ideas for Stuffable Toys

Stuffable toys are a lifesaver for keeping your dog busy, but buying pre-made fillings can get expensive fast. The good news?

You can whip up tasty, dog-safe fillings at home for just pennies. Whether you have a Kong, a Toppl, or a similar puzzle toy, these six ideas use simple ingredients you probably already have in your kitchen.

Your dog will love the challenge, and your wallet will thank you. Let's dive into some easy, budget-friendly recipes that will make treat time fun and affordable.

1. Peanut Butter & Banana Mash

This two-ingredient mash is a budget-friendly winner that most dogs go wild for. Ripe banana brings natural sweetness and potassium, while unsalted peanut butter adds protein and healthy fats. The key is using peanut butter with no xylitol—always double-check the label.

Freezing the filled toy turns snack time into a longer-lasting puzzle that keeps your pup busy without costing much.

Ingredients

• 1 ripe banana
• 2 tablespoons unsalted peanut butter (xylitol-free)
• 1 cup prepared ripe banana in small dog-safe pieces
• 1 cup oat flour or finely ground oats
• 1 egg or 2 tablespoons unsweetened applesauce for binding

Instructions

1. In a small bowl, mash the banana with a fork until smooth.
2. Stir in the peanut butter until fully combined.
3. Spoon the mixture into your dog's stuffable toy, then freeze for at least 2 hours before serving.
4. Mix the prepared ripe banana with the oat flour and binder until a soft dough or spoonable mixture forms.
5. Shape into small treat portions, bake on a lined tray at 325°F until firm, then cool completely before serving.

Serving Tip

This mash is soft enough to fill most toys easily. For extra firmness, freeze the filled toy overnight. Use within a day or two if refrigerated, or freeze in bulk and thaw as needed.

2. Plain Yogurt & Blueberry Swirl

This two-ingredient frozen swirl is a budget-friendly way to give your dog a probiotic boost. Plain yogurt is gentle on most tummies, and blueberries add natural sweetness and antioxidants. It's a cool, creamy treat that's easy to make and even easier to love.

Ingredients

• 1 cup plain, unsweetened yogurt (no xylitol)
• 1/2 cup fresh or frozen blueberries
• Optional: 1 tablespoon unsweetened applesauce for extra swirl

Instructions

1. In a small bowl, mash the blueberries with a fork until they release their juices.
2. Add the yogurt and stir just enough to create a swirl effect—don't fully mix.
3. Spoon the mixture into your dog's stuffable toy, then place it in the freezer for at least 2 hours until solid.

Serving Tip

This frozen treat is perfect for hot days or teething pups. Start with a small amount to see how your dog handles cold treats. For smaller toys, you can pipe the mixture in using a zip-top bag with the corner snipped off.

3. Pumpkin & Oatmeal Stuffing

This simple combo is a lifesaver when you want to stretch your dog treat budget. Canned pumpkin (just the plain stuff, not pie filling) is cheap and easy to find, and oatmeal is a pantry staple. Together they make a soft, fiber-packed filling that's gentle on sensitive stomachs.

Dogs love the mild, earthy flavor, and you can whip it up in minutes with zero fancy ingredients.

Ingredients

• 1/2 cup canned pumpkin (100% pure, not pie filling)
• 1/2 cup cooked plain oatmeal (cooled)
• 1 tablespoon plain yogurt (optional, for extra creaminess)

Instructions

1. In a small bowl, mix the pumpkin and cooked oatmeal until well combined. If using yogurt, stir it in now.
2. Spoon the mixture into your dog's stuffable toy, pressing it down gently. Refrigerate for at least 30 minutes to firm up before serving.

Serving Tip

This filling is soft when fresh but firms up nicely in the fridge, making it perfect for slower licking. Portion into a small toy for a quick snack or a larger one for a longer-lasting treat. Any leftover stuffing can be stored in an airtight container in the fridge for up to three days.

4. Sweet Potato & Apple Puree

This two-ingredient puree is about as budget-friendly as it gets, and it’s packed with vitamins A and C from the sweet potato plus fiber from the apple. Dogs love the naturally sweet taste, and the soft texture makes it easy to spoon into any stuffable toy. Plus, it’s a great way to use up a leftover baked sweet potato or that apple that’s a little past its prime.

Ingredients

• 1 medium sweet potato, baked or steamed until soft
• 1 small apple, peeled and finely grated
• Optional: a pinch of cinnamon (dog-safe, no xylitol)

Instructions

1. Let the cooked sweet potato cool completely, then peel off the skin and mash the flesh in a bowl until smooth.
2. Stir in the finely grated apple until well combined. Spoon the mixture into your dog’s stuffable toy, then freeze for at least 2 hours before serving.

Serving Tip

This puree can be stored in an airtight container in the fridge for up to 3 days. For a firmer texture that lasts longer in the toy, freeze the filled toy overnight. Adjust the amount based on your dog’s size—start with a tablespoon for small dogs and up to a quarter cup for large breeds.

5. Chicken & Carrot Broth Ice

When the weather heats up, a frozen treat can be a game-changer for your pup. This chicken and carrot broth ice is not only easy on your wallet but also super simple to make. It’s a hydrating, low-calorie option that keeps your dog entertained and cool.

Plus, you probably already have the ingredients in your kitchen.

Ingredients

• 1 boneless, skinless chicken breast
• 2 medium carrots, chopped
• 4 cups water

Instructions

1. Place the chicken breast, carrots, and water in a pot. Bring to a boil, then reduce heat and simmer for 20 minutes, or until the chicken is cooked through.
2. Remove the chicken and shred it with two forks. Transfer the carrots and broth to a blender and blend until smooth. Mix the shredded chicken back into the carrot broth.
3. Pour the mixture into your dog's stuffable toy and freeze for at least 4 hours, or until solid.

Serving Tip

This frozen treat is perfect for hot days or as a low-calorie reward. Make sure to supervise your dog while they enjoy it, and remove any small pieces that might break off. You can also make a big batch and store the mixture in ice cube trays for quick use.

6. Cottage Cheese & Spinach Blend

This creamy green blend is almost too easy—and your dog will think you spent hours on it. Cottage cheese is a budget-friendly protein source that's gentle on most stomachs, while spinach adds a boost of vitamins without any strong flavors. The result?

A smooth, savory filling that freezes beautifully and keeps your pup busy licking every last bit from their favorite toy.

Ingredients

• 1/2 cup low-fat cottage cheese
• 1 handful fresh spinach leaves
• 1 tablespoon water (optional, for thinning)

Instructions

1. Add the cottage cheese and spinach to a blender or food processor.
2. Blend on high until completely smooth, about 30 seconds. If the mixture is too thick, add a tablespoon of water and blend again.
3. Spoon the blend into a stuffable toy, then freeze for at least 2 hours before serving.

Serving Tip

This filling is best served frozen so it lasts longer. For smaller dogs, use a mini toy and fill with just a tablespoon or two. Any leftover blend can be stored in an airtight container in the fridge for up to 3 days—just give it a quick stir before using.
