How much blueberries for your dog?
Most guides say "a few pieces". Enter your dog's weight and get the actual daily ceiling, worked out from blueberries's calories and the 10%-of-daily-calories treat rule vets use.
Assumes a healthy, neutered adult at a stable weight, and that this is their only treat that day. Puppies, pregnant, very active or unwell pets need different amounts — ask your vet.
Why this verdict for dogs
Blueberries are a superfood treat — packed with antioxidants and low in calories.
Blueberries are a near-perfect treat — tiny, low-calorie, and packed with antioxidants — and they double as easy training rewards. Dogs love them by the handful; cats may nibble one or two.
How much is safe?
A small handful is a great treat for most dogs (fewer for small dogs); cats need only one or two. They're naturally lower in sugar than many fruits, so they're one of the more guilt-free options.
What happens if a dog eats too much?
Eating a lot can cause loose stool from the fiber; frozen ones can be a minor choking risk for very small pets (thaw or halve them).
How to serve it safely
Serve fresh or frozen and plain — frozen blueberries make a crunchy, mess-free training treat. Avoid muffins or anything with added sugar.
