Can Dogs Eat Blueberries?

What makes blueberries so healthy for dogs?

Blueberries are one of the most antioxidant-rich foods available, and that benefit extends to dogs. Antioxidants help fight free radicals, which contribute to cellular aging and disease. They also contain fiber for digestive health, vitamin C for immune support, and vitamin K for bone health. At only about 85 calories per cup, they deliver a lot of nutrition for very little caloric cost. Several studies have shown that antioxidant-rich diets can support cognitive function in aging dogs.

Fresh or frozen?

Both are great. Fresh blueberries are convenient and require no preparation. Frozen blueberries take longer to eat, which makes them a nice enrichment treat, and they are especially refreshing in warm weather. Avoid blueberries canned in syrup, since the added sugar defeats the purpose. Also skip blueberry-flavored products like muffins or yogurt, which contain ingredients dogs do not need.

How many can a dog eat?

For small dogs, a handful of blueberries (eight to ten) is a reasonable serving. Medium and large dogs can have more, but there is no need to go overboard. Too many at once can cause mild stomach upset or loose stools, mostly from the fiber content. A few blueberries several times a week is a great frequency. Their size makes them perfect for tossing one at a time during training sessions.
