| Vitamin K | Supports healthy bones |

9 Vet-Approved Benefits of Blueberries for Dogs
1. Rich in Powerful Antioxidants
One of the biggest reasons veterinarians recommend blueberries is their high antioxidant content. Antioxidants help protect the body’s cells from oxidative stress and may support healthy aging.
If you’re asking can dogs eat blueberries for long-term wellness, antioxidants are one reason they make a nutritious treat.
2. Supports Brain Health
Some research suggests that antioxidant-rich foods may help support normal brain function, particularly in senior dogs. While blueberries are not a treatment for cognitive decline, they can be part of a balanced diet that supports overall health.
3. Helps Maintain Healthy Digestion
Blueberries contain dietary fiber, which can support regular digestion when fed in appropriate amounts. Too many berries, however, may upset your dog’s stomach, so moderation is important.
4. Low-Calorie Training Treat
Because blueberries are naturally low in calories, many dog owners use them as a healthy reward during training sessions instead of high-fat commercial treats.
