Can Dogs Eat Blueberries? Benefits, Risks & Safe Portions
Yes – dogs can eat blueberries, and they're one of the best fruit treats you can offer. Blueberries are non-toxic, low in calories, and packed with antioxidants. The only real cautions are portion size and the small choking risk for tiny dogs.
The short answer
- Safe? Yes – a genuine superfood treat.
- How much? A few for small dogs, 8-10 for larger dogs (treats = max 10% of daily calories).
- Watch out for: overfeeding (loose stool) and whole berries as a choking risk for very small dogs.
Are blueberries good for dogs?
Blueberries are a rare treat that's actually good for your dog. They deliver:
- Antioxidants (anthocyanins) – help protect cells from damage and support overall health.
- Vitamin C and vitamin K – support the immune system and healthy blood clotting.
- Fiber – aids digestion.
- Low calories and high water content – great for dogs watching their weight.
Many dog foods and treats actually add blueberries for exactly these reasons. They're also small and soft, which makes them an easy training reward.
How many blueberries can a dog eat?
Follow the 10% treat rule – treats should be no more than a tenth of daily calories:
| Dog size | Example weight | Safe blueberry serving |
|---|---|---|
| Toy / very small | under 10 lb | 2-3 berries |
| Small | 10-25 lb | 4-5 berries |
| Medium | 25-50 lb | 6-8 berries |
| Large | 50-90 lb | 8-10 berries |
| Giant | 90 lb+ | up to ~¼ cup |
Start with a couple the first time and watch for any tummy upset before making them a regular treat.
How to serve blueberries safely
- Wash them to remove any pesticide residue.
- Serve plain – fresh or frozen, never in muffins or with added sugar.
- Mash or halve them for very small dogs and puppies to remove any choking risk.
- Freeze a handful for a cooling summer snack, or drop a few in a lick mat or puzzle toy.
Risks: when blueberries aren't a good idea
- Choking: whole berries can be a choking hazard for tiny dogs – mash them.
- Upset stomach: too many at once can cause diarrhea from the fiber and natural sugar.
- Blueberry products: muffins, pancakes, and dried-fruit mixes often contain sugar, butter, or xylitol. Avoid them.
Can puppies eat blueberries?
Yes – they're an excellent puppy treat. Once your puppy is eating solid food, offer one or two plain blueberries (mashed for tiny pups) and watch how they do. Their small size makes them perfect for training.
Can dogs eat blueberries every day?
A few each day is fine for most healthy dogs, as long as they stay within the 10% treat limit and the rest of the diet is a complete, balanced dog food. If your dog has a health condition, check with your vet first.
When to call your vet
Blueberries are very safe, but contact your vet if your dog:
- Has persistent diarrhea or vomiting after eating a large amount,
- Shows signs of choking on a whole berry,
- Or ate a blueberry product that may contain xylitol (sugar-free baked goods).
For suspected poisoning, call the ASPCA Animal Poison Control Center (888-426-4435) or Pet Poison Helpline (855-764-7661).
The bottom line
Blueberries are a safe, healthy, antioxidant-rich treat that most dogs love. Wash them, keep portions sensible, mash them for little dogs, and they're one of the best fruits you can share with your pup.
