I love making homemade treats when I can keep the ingredients simple and still make something my dog gets excited about. These sweet potato and blueberry chews are one of those recipes I keep coming back to because they use everyday ingredients and have a naturally sweet, fruity flavor without needing added sugar.
The sweet potato makes the dough soft and easy to work with, while blueberries add little bursts of flavor and color throughout the treats. I bake them until they’re firm around the edges but still have a slightly chewy texture in the middle.
They’re especially nice when you want a homemade treat that feels a little different from the usual crunchy dog biscuit.
Quick Answer
Yes, plain cooked sweet potato and blueberries can be suitable ingredients for many dogs when served in moderation. Sweet potato should be cooked and plain, while blueberries should be fresh or frozen and free from added sugar or syrup.
These homemade chews combine both ingredients with oat flour and egg to create a soft, chewy dog treat.

Why Sweet Potato and Blueberries Work Well in Homemade Dog Treats
Sweet potato gives these chews their soft texture and naturally sweet flavor. Once cooked and mashed, it also helps bind the dough without requiring much added fat.
It provides fiber and several nutrients, including beta-carotene, while blueberries contribute fiber and naturally occurring antioxidants.
The important part is keeping both ingredients plain. Sweet potato should be cooked before adding it to the recipe, and blueberries should not come packed in syrup or mixed with added sweeteners.
Because these treats contain concentrated ingredients in a smaller package, portion size still matters. Treats should remain a small part of your dog’s overall daily calorie intake.
How to Make Sweet Potato and Blueberry Chews for Dogs
Ingredients
- 1 cup cooked sweet potato, peeled and mashed
- ½ cup fresh or frozen blueberries
- 1½ cups plain oat flour
- 1 large egg
- 1 tablespoon coconut oil, optional
1. Cook the Sweet Potato
Peel the sweet potato and cut it into chunks.
Bake, steam, or boil until completely tender. Let it cool enough to handle, then mash it until mostly smooth.
Avoid adding butter, salt, sugar, milk, or seasoning.
2. Prepare the Blueberries
Wash fresh blueberries thoroughly.
If using frozen blueberries, thaw them first and drain away excess liquid.
Gently mash the berries with a fork. You don’t need to turn them completely into a smooth puree—leaving a few small pieces gives the finished chews little pockets of blueberry.
3. Make the Dough
Add the mashed sweet potato, blueberries, egg, and optional melted coconut oil to a mixing bowl.
Stir until combined.
Gradually add the oat flour, mixing as you go. The finished dough should be soft and workable rather than runny.
If it feels very sticky, add a little more oat flour. If it seems unusually dry or crumbly, add a teaspoon of water at a time until it comes together.
4. Roll and Cut the Chews
Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
Place the dough between two sheets of parchment and roll it to about ¼ inch thick.
Cut the dough into small strips, rectangles, or bone shapes.
Keep the pieces small enough to be an appropriate treat for your dog.
5. Bake
Arrange the chews on the prepared baking sheet with a little space between them.
Bake for 25–30 minutes, or until the treats are set and lightly browned around the edges.
For a softer chew, stay toward the shorter end of the baking time.
For a firmer texture, leave them in a little longer, watching carefully so they don’t become excessively hard.
6. Cool Completely
Transfer the treats to a wire rack and allow them to cool completely before serving.
They will firm up slightly as they cool.
Serving, Storage & Variations
How Much Should You Give Your Dog?
Start with a small piece when introducing the recipe for the first time.
A small dog may only need part of a chew, while a larger dog may be able to have a whole small chew. The right amount depends on the size of the treat, your dog’s normal diet, activity level, and total daily treat intake.
Remember that treats should generally account for no more than about 10% of a dog’s daily calories.
How to Store Them
Because these are homemade treats without commercial preservatives, I prefer keeping them refrigerated.
Store cooled chews in an airtight container in the refrigerator for up to 1 week.
For longer storage, place them in a freezer-safe container or bag and freeze for up to 3 months.
Thaw individual treats in the refrigerator or allow them to sit briefly at room temperature before serving.
For a Firmer Chew
If your dog prefers a firmer texture, roll the dough slightly thinner and extend the baking time carefully.
You can also allow the baked treats to cool completely and then return them to a low oven for additional drying.
The goal is a firm dog treat—not a rock-hard object that could be difficult for a dog to chew safely.
Can I Use Frozen Blueberries?
Yes. Frozen blueberries work well in this recipe.
Thaw them first and drain excess liquid so they don’t make the dough unnecessarily wet.
Can I Use Other Flour?
Plain oat flour is my preferred option here, but the recipe can be adjusted with another dog-appropriate flour if needed.
If changing the flour, add it gradually because different flours absorb moisture differently.
Common Mistakes
Using Sweet Potato With Added Ingredients
Plain cooked sweet potato is what you want.
Avoid sweet potato prepared with butter, sugar, salt, sauces, or seasoning blends.
Using Sweetened Blueberries
Don’t use blueberries packed in syrup or sweetened blueberry products.
Fresh or frozen plain blueberries are the simplest choice.
Making the Chews Too Large
Large treats can contribute more calories than expected and may be harder for smaller dogs to manage.
Cut the dough into appropriately sized pieces before baking.
Making Them Too Hard
These are homemade chewy treats, not long-lasting recreational chews.
Avoid baking them until they’re extremely hard or brittle.
Giving Too Many at Once
Sweet potato and blueberries can both contribute fiber. A large amount of a new treat may cause digestive upset, so start small and see how your dog handles it.
FAQ
Can dogs eat sweet potato and blueberries together?
Yes. Plain cooked sweet potato and plain blueberries can both be appropriate foods for many dogs when given in moderation.
Are these sweet potato blueberry chews healthy for dogs?
They can be a simple homemade treat option because they use sweet potato, blueberries, oat flour, and egg without added sugar or heavy seasoning. However, “healthy” doesn’t mean unlimited—portion size still matters.
Can puppies eat these chews?
Puppies may be able to have small amounts of dog-safe homemade treats, but their primary nutrition should come from a complete and balanced puppy diet. Introduce any new food gradually.
Can I make these without egg?
The egg helps bind the dough, so removing it will change the texture. You may need to adjust the amount of oat flour and moisture to get a workable dough.
Do these help clean a dog’s teeth?
No. These should not be considered a dental-care product. Their chewy texture does not replace regular tooth brushing, veterinary dental care, or products specifically designed for dental health.
Can dogs eat raw sweet potato?
Raw sweet potato is harder for dogs to digest and can be difficult to chew. For this recipe, always cook the sweet potato until soft before using it.
Can I use dried blueberries?
I wouldn’t use sweetened dried blueberries. Fresh or plain frozen blueberries are a better choice because they don’t bring unnecessary added sugar or concentrated sweeteners.
Conclusion
These sweet potato and blueberry chews are a simple way to turn a few basic ingredients into a homemade treat your dog can enjoy.
The sweet potato creates a soft, naturally sweet base, while blueberries add flavor and little pops of color throughout the chews. Bake them a little shorter for a softer texture or dry them longer if your dog prefers something firmer.
Most importantly, keep the ingredients plain, the pieces appropriately sized, and the portions modest. Homemade treats work best as a small addition to an otherwise complete and balanced diet.
