. . . . . . . . . . . . . . . . . . . . . . . . Judging the age of a dog mainly depends on the wear of the dog's teeth, and also refers to facial expression, posture and coat. And the occurrence of senile hair and the changes of senile eyes.
First, the wear and tear of teeth. Dogs give birth to deciduous teeth ten days after birth. After two months, front teeth, canine teeth and molars will be gradually replaced by permanent teeth. Permanent teeth will be replaced in 8- 10 months, but it takes 1 year and a half for teeth to grow firmly. It doesn't matter if the puppy swallows the replaced deciduous teeth, because the deciduous teeth are soft and the dog's gastrointestinal tract can be digested. Dog's tooth wear is related to age, and the older the dog, the more serious the wear is. However, we should also see that this has a lot to do with the food nature of animals. For example, if you eat soft food and chew bones frequently, the dog's teeth wear is different and can only be used as a reference. According to the teeth to estimate the age of the dog can refer to the table below:
Age | dental characteristics
Only deciduous teeth (white, thin and pointed) under 2 months old.
Replace the front teeth in 2-4 months.
Replace canine teeth (white teeth and blunt teeth) in 4-6 months.
Replace molars at 6- 10 months.
1 year-old, white and bright, without sharp front teeth.
The tip of the 2-year-old lower incisor was ground flat.
The tip of the 3-year-old upper incisor was ground flat.
At the age of 4-5, the upper and lower incisors began to wear slightly oblique and yellow.
6-8-year-old front teeth are exposed, canine teeth are yellow, and lips are pierced.
Second, facial expressions. 1 year-old dog with active expression and active eyes. Dogs of 2-4 years old are kind and approachable, full of energy and enthusiasm. Old dogs over 7 years old are mentally retarded, delayed in response to stimuli, unwilling to move more and have no eyes. Third, posture. Puppies are light and flexible when they move, clumsy when they are 2-5 years old, but stable, safe and reliable. /kloc-Old dogs over 0/0 years old are slow in behavior, with wrinkles or bends on their backs and slow in walking.
Fourth, the occurrence of senile hair. Refers to the appearance of gray hair (that is, dogs with non-gray hair become gray hair), which first occurs in the lip area and mandibular area. Dogs of 4-5 years old began to see a few white hairs, which increased obviously at 5-6 years old, and then spread to the back, around the nose, eyelids, eyebrows and so on. And then further spread to the forehead and external auditory canal, and even the whole head hair turned white. /kloc-dogs over 0/0 years old have too much white hair on the forehead, face and front of the head. /kloc-over 0/3 years old, the whole head turns white (there are also some dogs whose coat color remains unchanged when 10- 14 years old). For dogs whose coat color is white, yellow, white or chestnut white, the change of coat color cannot be used as an auxiliary means to judge age.
Fifth, the eyes. The puppy has bright eyes. Dogs over 7 years old have cataracts, and the incidence rate is high over 8 years old. Most dogs over 9- 10 years old have cataracts, and almost all dogs over 10 years old have cataracts. The lens of early cataract is blue-green ring. Typical central or central peripheral cataract, lens opacity is gray or grayish white, and there is obvious green refractive reflection. Individual dogs 1- 1.5 years old also have cataracts.

[* Guinness Book of Records]:
1. A dog born for one and a half months has deciduous teeth, and then the teeth gradually grow out.
2. In the fourth month, the front teeth with permanent teeth begin to grow, while the deciduous teeth of the front teeth will be squeezed out and fall off.
Molar teeth are born in the fifth month.
4. In the sixth month, canine teeth were born.
When I was one year old, all my teeth were full.
6. At the age of two, teeth will accumulate tartar.
7. By the age of three or four, the amount of tartar and filth will be obvious.
8. At the age of five, the tips of teeth began to wear out.
9. At the age of six, tartar accumulated and began to suffer from alveolar abscess.
10. When I was seven or eight years old, my teeth began to tremble.
1 1. At the age of ten, the front teeth with alveolar abscess fell off and the molars began to shake.
12. After the age of 14 or 15, canine teeth will fall off. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
The age of dogs can be calculated as follows: small dogs: long life span, about 14~ 16 years old. Because of this feature, it is very important for small dogs to make special feed.
Medium-sized dogs: the life span is about 14- 15 years. When they are 7 years old, providing proper feed will help them prolong their aging and stay healthy, and they may live longer.
The average big dog: its life span is about 10, so it ages faster. In order to overcome psychological defects as much as possible, adult dogs need to be strengthened. Generally speaking, purebred dogs have a shorter life span.
According to the calculation method of human life span, the age of a dog is one year after birth 17 years, 23 years after birth, and 28 years after birth. After that, the conversion of four years old will be increased every year. So 65,438+00 dogs are 55 years old. Recently, due to the improvement of nutrition, the life span of dogs has also been extended. The life span of a dog is about 13- 18 years, and the longest is over 20 years, but it is rare. The life span of dogs often has different results because of different breeds of dogs. There are many kinds of dogs, and how long they can live depends on their pedigree and breed. Secondly, the environment, hygiene, exercise, eating habits, feeding management and other factors have a certain impact on the dog's life. In general, the life span of large dogs is slightly longer than that of small dogs, hybrid dogs are longer than purebred dogs, male dogs are longer than female dogs, and domestic dogs are longer than stray dogs. The difference between dogs and people is that their old age is very short, and they can still live healthily six months before their death. Seven years after the birth of small or medium-sized dogs, or five years after the birth of large dogs, they have gradually entered old age. With the knowledge of dog life span, we can take care of dogs at different ages. In order to let the dog spend his last life happily, the dog owner should do more meaningful things for him. Especially when we know that the dog is old, we must choose a puppy in time to keep it, so as not to be too sad when the dog dies. Secondly, the young and energetic spirit of the puppy can infect the old dog and spend the last happy time with the old dog. Old dogs don't get depressed because they are old.
