Generally, puppies can be brought in two months after injection. It's best not to take it out five months ago, it's easy to get sick.

If you don't have any experience in raising a dog, you'd better bring it back after three months.

1. The joint is slightly shorter; The body length (the distance from the shoulder joint to the hip end) is slightly larger than the shoulder height (the vertical distance from the withers to the ground). The distance from the elbow to the ground is equal to half the height of the shoulder. The chest extends to the elbow, but it is not very impressive. The body must be long enough to allow straight, free and effective steps; But he can't appear too short in outline, too long or too high in body and too thin in legs.

2. Constitution: Constitution and bone mass account for the whole proportion. Weak and "useless" individuals must be simply eliminated. Similarly, rustic and clumsy individuals are not desirable. Labrador dogs must show muscles (developed) under working conditions, and cannot be obese. The ratio of body length to shoulder height is about 12: 1 1.

3. Head:

Wide head; It's clear but not exaggerated. The head and front face are in parallel planes, and the length is roughly equal. The stop is moderate and the eyebrows are slightly prominent, so the head is not a complete straight line to the tip of the nose. The brow bone emphasizes the stop. The head line is clear, the cheeks are not fleshy, the head bone line is clear, and the outline below the eyes is clear, but the cheeks are not prominent. The head is slightly exposed from the center line; The occipital bone of mature dogs is not significant. Lips should not be square or drooping. But it forms a curve towards the throat. A wedge-shaped head, or a head with a long back and a narrow mouth, is as wrong as a thick head and thick skin. The jaw is strong but not slender, and the muzzle is neither long nor narrow, nor short and thick.

4. Nose mirror:

The nose mirror is wide and the nostrils are very developed. The nose mirror of a yellow or black dog is black, and the nose mirror of a chocolate dog is brown. It is not a defect that the nose mirror fades into a faint shadow. A completely pink nose mirror or a nose mirror lacking any pigment is disqualified.

Teeth: teeth are firm and tidy, and bite like scissors. Clamp bite is acceptable, but not ideal. Teeth with prominent maxillary occlusion, prominent mandibular occlusion or teeth dislocation are serious defects. A complete dentition is ideal, and the lack of molars or premolars is a serious defect.

5. Ears:

Hanging, moderately close to the head, the position is good and reliable, slightly lower than the head; Slightly above eye level. Ears should not be too big or too heavy, but they should be in harmony with the proportion of the head. When they are pulled forward, they can extend into the eyes.

Eyes: Sharp and friendly eyes show good temperament, and intelligence and alertness are the characteristics of this breed. The eyes are of medium size, relatively open, not prominent or deep. Black or yellow dogs have brown eyes, and chocolate dogs have brown or hazel eyes. Black or yellow eyes make the expression dazzling and unwelcome. Small eyes, eyes that are too close, and round and prominent eyes are not typical eyes of this breed. Black or yellow Labradors have black eyes, and chocolate Labradors have brown eyes. Lack of pigment around the eyes is disqualification.

The neck has the correct length, which makes it easy for him to complete the recovery work. Muscular, no fat. The neck is firmly raised from the scapula and moderately arched. A short and thick neck or "sheep neck" is wrong.

Topline: The back is strong. When standing or exercising, the topline (from withers to hips) remains horizontal. In any case, as a sports dog, the waist obviously shows elasticity.
