Dogs can eat blueberries in moderation. They are non-toxic and rich in antioxidants and fiber, but too many may cause stomach upset due to natural sugars. Serve fresh or thawed and cut for small dogs to prevent choking.

Quick answer:
Safe in small portions. Avoid syrup-packed or sweetened blueberries.

How it works

Dogs process fruit sugars differently than humans. Blueberries contain natural fructose and fiber, which most healthy dogs can digest in small amounts. However, too much sugar can upset the stomach and may contribute to weight gain over time. Fortunately, Blueberries are at the lower end in terms of sugar content.

When to give Blueberries

  • Training rewards instead of commercial treats
  • Hydrating snack in hot weather
  • Low-fat alternative for overweight dogs
  • Occasional variety in a balanced diet
  • Avoid giving them daily.
