Why Blueberries Are a Canine Superfood

Brain Health & Cognitive Function

Blueberries are rich in anthocyanins — the compounds that give them their deep blue colour. Research shows these antioxidants help protect brain cells from oxidative stress and inflammation. Studies suggest they can improve memory and learning, making them especially valuable for senior dogs experiencing cognitive decline.
