3 thoughts on “What about the age of the dog”

  1. It is judged that the age of dogs mainly depends on the wear and falling of the dog's teeth. At the same time, it also refers to the facial expression, body posture, the occurrence of older hair and the changes in old -fashioned eyes.
    1, the wear and falling of the teeth.
    The milk teeth were born ten days after the dog was born. Two months later, the tooth, canine, and molars were gradually replaced by the tooth, 8-10 months, and the tooth was needed. Growth is solid.
    2, facial expression.
    dogs who are around 1 year old, with active expressions, eyesight and active eyes; dogs aged 2 to 4 years old, close to others, glowing, enthusiasm; old dogs greater than 7 years old, dull, right, right, right, right, right, right, right The stimulus response was slow, unwilling to move more, and his eyes were godly.
    3, posture.
    In young dogs, the body is light and spiritual. The activity is a bit clumsy at the age of 2 to 5, but it is stable, safe and reliable. Elderly dogs over the age of 10 have slow behavior, rolling or flexion, walking slowly.
    4, the occurrence of old hair refers to the appearance of gray and white hair (that is, the original non -gray hair dog becomes gray -white hair).
    In first in the lip area and lower jaw area. Dogs 4 to 5 years old began to see a few white hair; 5 ~ 6 years old increased significantly, and then spread to the back, around the nose, eyelids, eyebrows, etc., and further expanded to the long white hairs in the forehead and the outer ear canal, and even The entire head is white.
    This more than 10 -year -old dog's forehead, face and head with a large amount of white hair. The entire head of more than 13 becomes white (when there are also individual dogs 10-14 years old, the hair color remains unchanged). For dogs with white, yellow and white hair, or maroon -colored white spots, it cannot be used as an auxiliary means to judge age.
    5, eyes.
    The young dog's eyes are bright and bright. Dogs over the age of 7 have cataracts, cataracts over 8 years old, most of them have cataracts at the age of 9 to 10. cataract.
    The early cataract crystal is a blue -green ring. The typical cataract is in the central or central or centralized, the crystals are turbid or gray -white, and there are obvious green folding reflexes. Individual dogs also have white internal barriers from 1 to 1.5 years old.

  2. The life of dogs
    The work hard and extremely idle dogs, the life span of the two is very different, but no matter which dog, the life of the 15 years old is

    most commonly. As long as the breeder usually pays attention to the dog's body, exercise and disease health, most dogs have a long life.

    The difference between age
    Prepromus Babies will fall off 5-7 months after birth and give birth to permooth teeth.

    If the dog's milk teeth have fallen and the permanent teeth have not been exposed or exposed, the junction of the adult dog's upper and lower jaws is worn, adult dogs over 4 years old, 4 years old The upper and lower junction of the front teeth often becomes flat due to wear.

    For old dogs aged 7-8, the dog's age can be concluded according to the length of the dog's teeth.

    The age is generally only 5-6 months;

    It if all ministers of the teeth are all together, their age is about 8-12 months.

    In before adulthood, the growth state of the teeth shows the increase of the dog's age, but after adulthood, the age of the dog's age can be determined by the wear state of the teeth. Therefore, identifying the age of dogs requires certain practice and observation experience.
