How is Yorkshire considered to be in good condition

How is a Yorkshire of good quality? The purebred Yorkshire is about 23cm high at the shoulder, weighing no more than 3.2kg, with a small, even body; small head, flat top of the head, small, erect ears, almond-shaped eyes, moderate size, black nosepiece; straight limbs, standing perpendicular to the ground, rounded paws, and black nails. 1. The back is flat and straight. The head is small and flat at the top, and the skull should not protrude or arch. The muzzle should not be too long, the dog should not have a protruding upper jaw bite or a protruding lower jaw bite, and the teeth should be strong. A scissor bite or pincer bite is acceptable. 2. The facial nosepiece is black. The eyes are medium sized and do not protrude; they are dark and bright, revealing a sharp and intelligent gaze. Rims of the eyes are dark in color. Ears are small, V-shaped, erect ears, and the root of the ears should not be positioned too far apart. The neck, back line and body are in compact proportion.3. The front legs of the limbs are straight and the elbows are neither turned inward nor turned outward. From the rear, the hind legs are straight, while from the side, the hind knee joints are at an appropriate angle. The hind legs must be removed if they have wolf claws, and the front legs can be removed if they have wolf claws. The paws are round and the nails are black.4. The middle part of the tail is broken off and covered with long hair, kept lower than the back, with a high tail heel.5. The hair on the tail of a good quality Yorkshire is abundant, of medium length, and about the same length above, on the sides and below, like a fox’s tail, just below the dorsal line, and the Yorkshire tail is not curled on either side of the body when held up, nor is it flat on the back. The coat should be double-layered, medium-length, and seemingly dense, but not so long as to obscure the Yorkshire’s own clear outline. The undercoat should be soft, dense and long enough to support the outer coat. The outer coat should have straight, coarse hairs that are smooth and flat, not coarse and not upright.
