Eric asks Dr. Azza if dogs can eat blueberries, and the answer is yes. Dr. Azza explains that blueberries are packed with antioxidants, vitamin C and fiber to support immune and digestive health while making a low-calorie option for training treats. They can be served fresh or frozen, but should be thoroughly rinsed, offered in moderation and appropriately sized for smaller dogs to reduce the risk of choking.
