Is Blackberries safe for dogs?

Blackberries are low in sugar and rich in fibre, antioxidants and vitamins, making them a healthy occasional treat, fresh or thawed. They contain trace natural amounts of xylitol, which is toxic to dogs in large quantities, so keep servings modest — a few berries rather than a bowlful. Eating a lot at once can cause a mild upset stomach.

Symptoms to watch for

• Mild stomach upset
