Strawberries are good for dogs, and they are nutritious as well, according to Paw Nation. Strawberries are rich in vitamin C and antioxidants. They are high in natural sugars, so do not overdo it on feeding strawberries to dogs; the Dog Channel suggests one-half to one strawberry.
Strawberries are high in fiber, which is good for a dog's digestion. They also can whiten a dog's teeth through a special enzyme. Other vitamins and minerals in strawberries include potassium, copper, iron, manganese and magnesium. A frozen strawberry can make for a great dog treat, and it is easy to keep on hand.
