Yes, dogs are allowed to eat blueberries. Blueberries are safe and healthy for dogs when given in moderation. They are low-calorie treats packed with antioxidants, fiber, vitamins (such as vitamin C and K), and minerals that support immune health, digestion, and may help fight inflammation and aging effects in dogs. Fresh or frozen blueberries are good options, but avoid canned or sweetened blueberries as they may contain harmful sugars or additives. Since blueberries are small, they can be a choking hazard especially for smaller dogs, so it is important to feed them in appropriate portion sizes. Generally, treats like blueberries should make up no more than 10% of a dog's daily diet. It is advisable to wash blueberries thoroughly before feeding and consult a veterinarian for personalized advice, especially if the dog has any health conditions or special dietary needs.
