7 Antioxidant-Rich Berries That Support Your Dog’s Immune System

Blueberries are one of the most antioxidant-rich fruits available, making them a top choice for boosting your dog’s immune system. These small but powerful berries contain high levels of vitamin C, fiber, and anthocyanins — plant compounds that help fight oxidative stress. Blueberries can also help support brain health and improve memory in aging dogs. For a delicious and convenient way to include this superfruit in your dog’s meals, try the Beef Topper with Carrots and Blueberries (on Amazon). This topper adds real blueberry nutrition to your dog’s food in a flavor they’ll love.

Cranberries are well known for their urinary tract benefits, but they’re also loaded with antioxidants that help the immune system fight off free radicals. These red berries are packed with vitamins C, E, and K, which all play roles in immune support and cellular health. A great way to provide your dog with the benefits of cranberries is the Extra Strength Urinary, Bladder, and Kidney Support for Dogs with Cranberry (on Amazon). It’s specially formulated to help maintain a healthy urinary system while delivering powerful antioxidants to support immune health.
