fruit
Blueberries
SAFE
Yes. Plain blueberries are a safe, low-sugar treat for most dogs.
What to do
No action needed for a normal treat amount.
When to contact a vet: Only if your dog is choking, repeatedly vomiting, or has eaten a baked product containing xylitol or chocolate.
Symptoms to look for
- loose stools if too many are given
Why
Blueberries are not toxic to dogs. They are small, low in fat and lower in sugar than many fruits, which makes them a practical training treat. Because they are small and firm they can be a choking risk for very small dogs, and frozen berries are hard, so consider thawing or halving them. Too many at once can cause loose stools.
- Safer parts
- The whole fresh or thawed berry.
- Parts to avoid
- Blueberry muffins, pies and other baked products, which may contain xylitol, chocolate or a lot of sugar.
- Preparation
- Wash them and serve plain. Halve or thaw for small dogs.
- How much matters
- A small handful is plenty for a medium dog; fewer for a small dog.
- Severity
- Low
