🫐 Why Blueberries Are Good for Pets
1. Rich in Antioxidants
Blueberries are loaded with anthocyanins — plant compounds responsible for their blue color and antioxidant power. Antioxidants help neutralize free radicals, reducing oxidative stress in the body.
2. Low in Calories
One cup of fresh blueberries contains about 84 calories, making them a great low-calorie training treat for dogs.
3. Nutrient Dense
They contain vitamin C, vitamin K, manganese, fiber, and potassium — nutrients that support overall wellness.
4. Research in Dogs
-
Sled dog study: Dogs fed blueberries after exercise had higher antioxidant status within 48 hours compared to controls.
-
Short-term feeding: A 4-week blueberry-supplemented diet improved oxidative balance in active dogs.
⚠️ Are Blueberries Safe for Pets?
For Dogs: Yes, blueberries are safe in moderation for healthy dogs. Avoid sweetened or canned blueberries.
For Cats: Safe in very small amounts. Cats are obligate carnivores and don’t require fruit, but they can have 1–2 blueberries as an occasional treat.
Avoid in:
-
Pets with diabetes (due to natural sugars)
-
Pets on strict prescription diets
-
Pets prone to calcium oxalate bladder stones (consult your vet first)
