# Can Dogs Eat Blueberries UK?

**Yes — blueberries are a safe, low-calorie treat for most dogs.** Fresh or frozen both work, served plain. They are small enough that **choking risk is low**, but mash them for tiny dogs and puppies. As with any treat, a few is plenty — too many can upset the stomach.

## 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](/health/dog-obesity-uk) 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](/health/what-fruit-can-dogs-eat-uk) 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
