Can Dogs Eat Blueberries? Fresh or Frozen, How Many, and What to Skip
Can dogs eat blueberries? Ours do, and they like them fresh or frozen. We have five dogs, and three are full Siberian huskies. We also have a local coffee and bagel shop called Tandem Bagel, and their pup cup is a little cup of whipped cream with a few blueberries on top. Two of my huskies will eat the berries. One, Lucy, will eat the whipped cream and pick around them. So I wanted to know what veterinary sources really say about dogs and blueberries.
This is my family’s experience, not veterinary advice. The information here is current as of October 2026, and guidance can change. Every dog is different, so please ask your own vet before you change your dog’s diet.
The Short Answer
Yes. PetMD, in an article reviewed by a veterinarian, says, “Yes, most dogs can safely eat blueberries when served plain and in moderation.” The American Kennel Club agrees: “Yes, dogs can eat blueberries.”
Here is the quick version:
- Safe: plain blueberries, fresh or frozen, washed first.
- Watch: small dogs, since a round berry can be a choking risk.
- Skip: blueberry muffins, most blueberry yogurts, and anything with added sugar or sweeteners.
- Ask your vet: how many are right for your dog, especially if your dog has diabetes or another health condition.
Fresh or Frozen?
Both are fine. The AKC says, “You can feed your dog both fresh and frozen blueberries.” PetMD adds that frozen blueberries “are safe for most dogs and can be a refreshing treat during warm weather.”
That matches our house. Ours like them either way.
Wash them first. The AKC says to make sure the berries “are thoroughly washed to remove any pesticides or dirt.”
How Many Blueberries Can a Dog Have?
Blueberries are a treat. Both sources use the same rule. The AKC says, “All treats should make up no more than 10% of your dog’s daily diet.”
PetMD gives a serving guide by size:
| Dog size | Serving |
|---|---|
| Extra-small (2 to 10 pounds) | 1 to 2 blueberries |
| Small (11 to 20 pounds) | 2 to 3 blueberries |
| Medium (21 to 50 pounds) | 3 to 5 blueberries |
| Large (51 to 90 pounds) | 5 to 6 blueberries |
| Extra-large (91 pounds and up) | 6 to 10 blueberries |
Those numbers are smaller than many people expect. More is not better. PetMD warns, “Feeding too many blueberries at once may lead to gastrointestinal upset, including stomach discomfort, gas, or diarrhea.”
These are general amounts. Your vet can set the right number for your dog.
The Choking Question
Blueberries are small, so you do not need to cut them for most dogs. Small dogs are the exception to think about.
- PetMD says, “Because blueberries are small and round, they can present a choking risk for some dogs, particularly small breeds.”
- The AKC notes “there are still potential risks, such as choking, especially to smaller dogs.”
If you have a tiny dog, or a dog who gulps food, you can mash or halve the berries. That is my common sense, not a quoted rule. Frozen berries are harder, so take extra care with small dogs.
Are Blueberries Good for Dogs?
They have real nutritional value. The AKC says blueberries “are low in calories and contain high amounts of vitamin C, fiber, and phytochemicals.” PetMD lists vitamin C, vitamin A, vitamin K, calcium, phosphorus, potassium, and magnesium.
Both sources mention antioxidants. The AKC explains that antioxidants “help fight free radicals, which are responsible for cellular and molecular damage.”
Keep it in perspective. A few berries are a healthy treat, not a treatment. A dog on a complete and balanced food already gets what it needs.
Blueberry Foods to Skip
Plain berries are the safe version. Blueberry-flavored foods are a different story.
- Blueberry muffins. PetMD says they “are not recommended because they often contain added sugar, fats, and potentially toxic ingredients.”
- Blueberry yogurt. PetMD says most “are not recommended because they often contain added sugars or artificial sweeteners such as xylitol, which is toxic to dogs.”
- Dried blueberries. PetMD allows them only “if they do not contain added sugar, preservatives, or other harmful ingredients.” Read the label.
- Anything sugar-free. The FDA warns that xylitol is toxic to dogs. It can also be listed as birch sugar.
What About Pup Cups?
Since a pup cup is how my dogs get blueberries when we are out, I looked for veterinary guidance on the whipped cream part. The two sources I used for this post do not cover whipped cream, so I will not make claims about it here.
What I can say is simple. The blueberries on top are the part the vets approve of. The whipped cream is a once-in-a-while extra at our house, not a regular thing. If your dog has a sensitive stomach or a health condition, ask your vet before you order one.
Lucy would tell you the whipped cream is the whole point.
Puppies, Diabetic Dogs, and Wild Blueberries
- Puppies. PetMD says, “Yes, puppies can safely eat blueberries in moderation as long as the berries are prepared appropriately.” Check with your vet first.
- Dogs with diabetes. PetMD says they “should generally avoid high-sugar fruits unless approved by a veterinarian.”
- Wild blueberries. PetMD says they “are also safe for dogs,” but owners should not let dogs eat large quantities. Be sure you know what the plant is before your dog eats anything growing wild.
Frequently Asked Questions
Can dogs eat frozen blueberries?
Yes. The AKC says you can feed “both fresh and frozen blueberries.” Take extra care with small dogs, since frozen berries are firm.
How many blueberries can a dog eat a day?
PetMD’s guide runs from 1 to 2 berries for extra-small dogs up to 6 to 10 for extra-large dogs. Treats should stay under 10% of the daily diet.
Can puppies eat blueberries?
PetMD says yes, in moderation and prepared appropriately. Ask your vet first.
Can dogs eat blueberry muffins?
No. PetMD says muffins often contain added sugar, fats, and potentially toxic ingredients.
Can blueberries upset a dog’s stomach?
Too many can. PetMD lists stomach discomfort, gas, and diarrhea.
Do I need to cut blueberries for my dog?
Not for most dogs. For small breeds, both sources mention a choking risk, so mashing or halving them is a reasonable precaution.
Can diabetic dogs eat blueberries?
Only with a vet’s approval, according to PetMD.
The Bottom Line
So, can dogs eat blueberries? Yes. Serve them plain, washed, and in small amounts, fresh or frozen. Be careful with small dogs, and skip the muffins and sweetened yogurt. Two of my huskies will happily take the berries. Lucy will keep eating around them.
