Can dogs eat blueberries?
Yes — according to the PDSA and Blue Cross, blueberries are one of the safest fruits to share with a healthy UK dog. They are bite-sized, low in calories compared with many commercial treats, and contain antioxidants — which is why they are so popular as training rewards.
They still contain natural sugar and fibre, so the same rule applies as with any fruit: treats should make up only a small part of your dog's daily diet.
Blueberries by type — what is safe?
| Type | Safe? | Notes |
|---|---|---|
| Fresh blueberries | Yes | Wash and serve plain |
| Frozen blueberries | Yes | Soften or mash for tiny dogs |
| Mashed blueberries | Yes | Safest option for puppies and toy breeds |
| Dried blueberries | Small amounts only | Concentrated sugar; check for added sweeteners |
| Blueberry muffins, pancakes and jams | No | Sugar, fat — may contain chocolate or xylitol |
How many blueberries can a dog eat?
| Dog size | Example portion |
|---|---|
| Small (under 10 kg) | A few berries, mashed if tiny |
| Medium (10–25 kg) | A few berries |
| Large (25 kg+) | A small handful |
Offer blueberries occasionally, not at every meal. Too many cause soft stools or diarrhoea — if that happens, stop treats and return to normal food.
Why blueberries suit training
Because they are small and low in calories, a few blueberries can reward a training session without loading your dog with fat. That makes them a better pick than rich treats for dogs watching their weight — though dogs with obesity or diabetes should still have treats agreed with your vet.
Blueberries sit firmly on the safe side of the fruit list — grapes and raisins are the toxic ones, with no safe dose. See what fruit can dogs eat for the full picture.
When to call your vet
Phone your vet if your dog:
- Chokes on a berry — gagging, pawing at the mouth, distress
- Vomits repeatedly or has diarrhoea that does not settle after eating blueberries
- Ate a blueberry product that could contain xylitol or chocolate — treat this as urgent
- Has diabetes and you are unsure whether fruit treats are appropriate
