Yes — safe in moderation
Yes — blueberries are one of the healthiest treats you can give a dog: tiny, low-calorie and full of antioxidants. Many trainers use them instead of shop-bought treats.
Blueberries are often called a superfood for dogs for the same reasons as for humans: anthocyanin antioxidants, vitamins C and K, and fibre — all at about 1 calorie per berry. Studies in working dogs suggest antioxidant-rich diets may help with age-related cognitive decline. Their size makes them perfect training treats, fresh or frozen. The only real cautions are quantity (fibre!) and choking risk for tiny breeds if gulped frozen.
Up to 8–10 berries a day for a medium dog, fewer for toy breeds. Frozen blueberries straight from the freezer are a favourite summer snack. Avoid blueberry muffins, pancakes or jams — it’s the added sugar, fat and possible xylitol that cause problems, not the berries.
Rotate with strawberries, apple slices or cucumber for variety without calories.
