Bottom line: Yes, dogs can eat blueberries. They are one of the safest and healthiest fruit treats you can share with your dog, low in calories, high in antioxidants, and small enough to avoid the choking and blockage risks of larger fruits. Feed in moderation as a treat.
| Situation | Suggested action |
|---|---|
| Dog ate a few blueberries | No action needed, blueberries are safe |
| Dog ate a large handful | Monitor for mild stomach upset; usually no action needed |
| Dog ate blueberries with sugar or syrup added | Watch for vomiting; call vet if concerned |
| Dog ate blueberry muffin or baked goods | Check for xylitol; call vet if unsure |
Are blueberries safe for dogs?
Yes. Blueberries are frequently recommended by vets as a healthy treat because they offer:
- Antioxidants (anthocyanins), help protect cells from damage and support ageing dogs
- Vitamin C and K, support immunity and blood health
- Fibre, aids digestion
- Low calories, around 57 kcal per 100g, making them ideal for weight management
They are also small and soft, so they are easy for dogs of all sizes to eat without the choking risk of larger fruits.
How many blueberries can a dog eat?
Because they are low in calories, blueberries are a great daily treat in small amounts. A rough guide:
- Small dogs (under 10 kg): 2–4 blueberries a day
- Medium dogs (10–25 kg): 4–6 blueberries
- Large dogs (over 25 kg): up to a small handful
Treats of all kinds should still make up no more than 10% of your dog's daily calories.
What are the risks?
Blueberries are very low risk, but keep the following in mind:
- Sugar: Although low in calories, blueberries do contain natural sugar. Diabetic dogs should only have small amounts with vet guidance.
- Added ingredients: Blueberry muffins, blueberry yoghurt, and blueberry baked goods often contain sugar, butter, and sometimes xylitol, a sugar substitute that is highly toxic to dogs. Feed only fresh or plain frozen blueberries.
- Overfeeding: A large amount at once can cause loose stools.
How to feed blueberries safely
- Wash fresh blueberries before feeding
- Offer them whole to medium and large dogs
- Cut in half for very small dogs or puppies to reduce choking risk
- Freeze them for a cooling summer treat
- Use a few as a low-calorie training reward
When to call the vet
Call your veterinarian if your dog:
- Eats blueberry products containing xylitol or raisins (some fruit mixes contain raisins, which are toxic, see our grapes and raisins toxicity guide)
- Develops vomiting, diarrhoea, or signs of an allergic reaction after eating blueberries
- Is diabetic and has eaten a large amount
