Blueberries
Also known as: wild blueberries
One of the most antioxidant-dense foods dogs can eat.
What it actually is
The berry of the Vaccinium plant. Fresh, frozen, or freeze-dried.
Why it's used in dog food
Extremely high in anthocyanins — antioxidants shown to reduce oxidative stress, support cognitive function in senior dogs, and lower inflammation.
A bit of history
Wild blueberries have been foraged in North America for thousands of years. Added to pet food commercially in the mid-2000s when antioxidant science hit consumer marketing.
Pros
- •Highest antioxidant content of any common fruit
- •Low in sugar and calories
- •Small, portable, and safe as a training treat
- •Cognitive support benefit is backed by canine research
Cons
- •Whole blueberries can be a choking hazard for very small dogs — halve or crush
- •A tiny amount in kibble is often for label appeal rather than functional dose
Safety notes
Fully safe. Feed in moderation — a small handful is plenty.
