A handful of blueberries is already a decent dog treat on its own. Bake them into soft little bites, though, and you get something that travels well, stays in one piece and doesn’t roll under the couch. These blueberry dog treats use three ingredients and a teaspoon, no rolling or cutting required. Inside: the recipe, simple no-bake ways to serve berries, how many bites to give by size, storage, and the berries that should never reach your dog.
Prep: 10 minutes • Bake: 15–18 minutes at 350°F (175°C) • Yield: about 40 teaspoon-size bites • Difficulty: Easy • Storage: fridge up to 1 week, freezer 3 months
Each bite has roughly 13 calories, light enough for frequent rewards.

Why Blueberries Work in Dog Treats
Blueberries are low in calories and bring fiber, vitamin C and antioxidants, which is why they show up in so many dog treat recipes. Baking them into a dough has a few practical advantages over serving them loose:
- Less choking risk: mashed berries can’t be gulped whole, which matters for toy breeds.
- Less mess: no stray berries squashed into the carpet.
- Easier to dose: one bite equals one reward, so counting treats is simple.
For the full rundown on serving fresh and frozen berries, see our guide to blueberries for dogs.
Ingredients for 3-Ingredient Blueberry Dog Treats
- ½ cup fresh or thawed frozen blueberries: rinsed and roughly mashed with a fork.
- 1 large egg: binds the dough.
- 1 cup (about 104 g) oat flour: blend rolled oats until powdery if you don’t have any. Add up to 2 tablespoons more if the dough is wet.
Use plain berries only. Skip anything packed in syrup or sold as pie filling.
How to Bake the Blueberry Bites
3-Ingredient Blueberry Oat Dog Treats
Ingredients
Method
- Heat the oven to 350°F (175°C) and line a baking sheet with parchment.
- Whisk the egg into the mashed blueberries, then stir in the oat flour until a thick, scoopable dough forms.
- Drop teaspoon-size mounds about an inch apart and flatten each slightly with a damp finger.
- Bake 15 to 18 minutes, until firm and lightly golden underneath.
- Cool on the tray.
Notes
No-Bake Ways to Serve Blueberries
Not in the mood to bake? Plain berries are already a ready-made reward:
- Frozen food topper: scatter a few frozen blueberries over dinner for a cold crunch. Halve them for small dogs.
- Sniffing game: hide berries in a snuffle mat or toss them across the lawn and let your dog search.
- Blueberry swirl: stir a few into plain canned pumpkin or plain yogurt and freeze in a mold. Our frozen dog treats guide has more ideas like this.
- Berry mix: combine with sliced strawberries for a colorful training pouch.
How Many Blueberry Bites Per Day?
Using USDA FoodData Central values, the batch adds up to about 530 calories: oat flour (~420), egg (~72) and blueberries (~42). Divided into 40 bites, that’s roughly 13 calories each.
The WSAVA treat guide recommends keeping treats below about 10% of daily calories. If these bites are the day’s only treats:
| Dog Size | Weight | Bites Per Day | Approx. Calories |
|---|---|---|---|
| Toy | Under 10 lb | 1–2 | 13–26 kcal |
| Small | 10–25 lb | 2–4 | 26–52 kcal |
| Medium | 25–50 lb | 4–6 | 52–78 kcal |
| Large | 50–90 lb | 6–10 | 78–130 kcal |
| Giant | 90+ lb | Up to 12 | ~156 kcal |
Estimates for healthy adult dogs. Use fewer on days with other treats, and ask your vet about puppies or dogs on a weight plan.
Storage and Safety
Fruit keeps these bites moist, so they spoil faster than dry biscuits. Refrigerate in a sealed container for up to a week, or freeze for up to 3 months and thaw a few at a time.
Blueberries are safe; these aren’t. Grapes and raisins can cause kidney damage, according to the ASPCA, so never swap them in. Skip blueberry muffins, jam, pie filling and sweetened yogurt, which can contain sugar or xylitol, and don’t let your dog eat wild berries you can’t identify. If your dog eats something risky, call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435.

Frequently Asked Questions
Are too many blueberries bad for dogs?
Too many at once can cause an upset stomach or loose stool because of the fiber and natural sugar. Stick to small portions and you’ll rarely see more than the occasional blue-tinged poop.
Can I put frozen blueberries in my dog’s food?
Yes. Plain frozen blueberries with no added sugar make a crunchy topper. For toy breeds and fast eaters, halve them or let them thaw slightly first.
What can I mix with blueberries for my dog?
Plain canned pumpkin, plain unsweetened yogurt, oats, sliced strawberries and xylitol-free peanut butter all pair well. Keep combinations simple and add one new food at a time.
Which berries can dogs not eat?
Grapes are the big one. Also keep dogs away from holly, yew, mistletoe and any wild berry you can’t identify. Cherries are risky because of the pits, stems and leaves.
Why do dogs struggle to eat blueberries?
Small, round and slippery, blueberries can roll around in the mouth, and some dogs dislike the burst of juice. Mashing them into baked bites solves both problems.
