Purity and purity of a black Teddy can be judged from four aspects: facial features, hair, color and body shape. The nose, eyes, and mouth of a pure Teddy are all black, and they are all relatively petite. Teddy's hair is curly, so the better the curl, the purer the Teddy. A black Teddy needs to have no stray hairs and a uniform color. If there is gray hair, it may be a gray Teddy. The standard Teddy has a shoulder height of 35 to 45 centimeters, the Giant Teddy has a shoulder height of 45 to 60 centimeters, the Mini Teddy has a shoulder height of 28 to 35 centimeters, and the Toy Teddy has a shoulder height of 24 to 28 centimeters.
