The blueberry bush (Vaccinium sect. Cyanococcus) is a flowering shrub that produces berries with a bluish, purple hue — also known as blueberries.
It is closely related to similar shrubs, such as those that produce cranberries and huckleberries.
Blueberries are small — around 0.2–0.6 inches (5–16 millimeters) in diameter — and feature a flared crown at the end.
They are green in color when they first appear, then deepen to purple and blue as they ripen
Blueberries are sweet, nutritious and wildly popular.
Often labeled a superfood, they are low in calories and incredibly good for you.
They’re so tasty and convenient that many people consider them their favorite fruit.
Unsurprisingly, they’re also good for your dog. All the antioxidants, fiber and phytochemicals blueberries boast provide the same benefits for your dog’s body that they give yours. Try frozen blueberries make for a crunchy treat dogs love.
