Yes. Blueberries are safe for dogs and are one of the better human-food treats you can offer — low in calories, high in fibre and antioxidants, with none of the toxicity concerns that apply to grapes or raisins.
Unlike grapes, blueberries don't contain tartaric acid or any compound currently linked to toxicity in dogs. They're rich in anthocyanins (the antioxidant compounds that give them their colour) and fibre, at a fraction of the calories of most commercial dog treats. This makes them a reasonable option for weight-conscious feeding, including for dogs on a diet plan.
For very small dogs or dogs that tend to gulp food without chewing, whole blueberries can pose a mild choking risk, similar to any small, round food. Lightly squashing them before serving to a small or enthusiastic eater removes this risk entirely.
As with any treat, the general rule is that treats shouldn't exceed about 10% of a dog's daily caloric intake. For most dogs, a small handful of blueberries a few times a week fits comfortably within that — small breeds should stick to just a few at a time.
