Yes — blueberries are one of the safest and healthiest treats you can give your dog. They're low calorie, packed with antioxidants and vitamin C, and small enough to use as training rewards. Limit to about 10 berries per day for medium-sized dogs to avoid GI upset.
Why Is Blueberries Generally Safe for Dogs?
Blueberries are widely considered a "superfood" for dogs. Per the American Kennel Club, they are rich in anthocyanins (the pigments that give them their color), vitamin C, vitamin K, manganese, and dietary fiber. Anthocyanins are powerful antioxidants linked to reduced oxidative stress in aging dogs.
At only about 1 calorie per berry, they're an excellent low-cost training reward and a smart alternative to processed treats. They're often included in commercial dog foods marketed for cognitive support and senior wellness, and they're listed as "safe" by both the ASPCA and the Pet Poison Helpline.
What Should You Do If Your Dog Ate Blueberries?
- 1Stop access immediately. Remove your dog from the area and pick up any remaining blueberries. Note the approximate amount eaten, the form, and the time of ingestion.
- 2Estimate dose by body weight. Knowing your dog's weight in pounds and the estimated amount consumed lets the poison line or vet decide whether observation or decontamination is needed.
- 3Call a poison control line first. Call ASPCA Animal Poison Control (888-426-4435) or the Pet Poison Helpline (855-764-7661). Both charge a consultation fee but give a written case number your vet can reference.
- 4Do NOT induce vomiting on your own. Hydrogen peroxide can cause severe esophageal ulceration if used incorrectly or with the wrong toxin. Only induce vomiting under direct veterinary instruction.
- 5Go to the ER vet if symptoms appear. Seek emergency care immediately for vomiting, tremors, weakness, collapse, seizures, or labored breathing — or proactively for any ingestion of grapes, xylitol, or large doses of a known toxin.
- 6Bring the packaging or sample. Bring the wrapper, ingredient list, or a photo of the food. This helps the veterinary team confirm the toxin and choose the right antidote or supportive plan.
When Should You Call Poison Control vs. the ER Vet?
Call Poison Control first if…
Your dog ate a small or unclear amount and is still acting normally. Have the wrapper, label, or a photo of the food ready.
- ASPCA APCC: 888-426-4435 (consultation fee)
- Pet Poison Helpline: 855-764-7661 (consultation fee)
Go directly to the ER vet if…
- Vomiting that won't stop, bloody diarrhea, or collapse
- Tremors, seizures, or unsteady gait

- Known ingestion of xylitol, grapes, raisins, or large chocolate doses
- Difficulty breathing or extreme weakness
What Are Safer Alternatives?
- Strawberries (small pieces, no stem) — also rich in vitamin C.
