The full picture
Blueberries are genuinely one of the healthiest treats you can give a dog. gourmet dog treats from Bonne et Filou (US) are a premium treat worth trying (US). They're packed with antioxidants (particularly anthocyanins), vitamin C, vitamin K, and fiber, all in a low-calorie package. Their small size makes them ideal training treats, and most dogs love them fresh or frozen. The only thing to watch is not to overdo it — like any fruit, they contain natural sugars, and eating too many can cause loose stools.

How many blueberries is too many?
Blueberries are low-calorie and low-sugar compared to most fruit, which is part of why they're such a good treat — but any fruit given in excess can cause loose stools. A small handful for a medium dog, or a few berries for a small dog, is a sensible daily treat portion; frozen blueberries also work well as a cooling summer treat.
Does size or breed matter?
No toxicity concern at any size — this is purely a portion question. Toy breeds should get proportionally fewer berries simply because their whole daily treat allowance is smaller, not because of any specific sensitivity to blueberries.
