How long can a dog live at most? What is the average life span of a dog

Dogs are the best friends of human beings. They can't accompany us for life, but they will accompany us for life. For many dog owners, they want their dogs to live longer. How many years can a dog live at most? How long is the average life span?

1、 What is the life span of a dog? The average life span is 12-15 years

The life span of dogs is generally between 12 and 15 years old, and the longest is more than 20 years, but it is rare. The average life span is about 12.6 years old, and the highest record is 34 years old.

The life span of the general breeding dogs, or "watchdog" as we often say, is longer because of their own good system.

In addition, hybrid dogs have a longer life than purebred dogs, small dogs have a longer life than large dogs, black dogs have a longer life than other dogs, small and medium-sized dogs have been born 7 years, or large dogs have been born 5 years, they have gradually entered the old age.

In addition: 2-5 years old is the prime age of dogs, and the aging phenomenon begins to appear after 7 years old. About 10 years old, reproductive capacity stopped. Statistics have been made abroad that the life span of dogs is related to breed, breeding management and other conditions. For example, hybrid dogs live longer than purebred dogs, small dogs live longer than large dogs, male dogs live longer than female dogs, indoor dogs live longer than outdoor dogs, and even black dogs live longer than other color dogs, among which indoor dogs account for the highest proportion. Therefore, it is known that the quality of feeding management is an important factor affecting the life span of dogs.

2、 Life algorithm of dog

A dog's week is a man's month

The duration of pregnancy in humans is 9 months, while in dogs it is only 9 weeks. Therefore, a dog's week is equivalent to a man's month: in addition, human beings have long deciduous teeth at the age of 8 months, and at the age of 2 years, while dogs begin to have deciduous teeth at the age of 3 weeks, and at the age of 6-8 weeks. People change their teeth between the ages of 6 and 13, while dogs change their teeth within 3 months to 6 months. According to this calculation, every 20 days in a year when a dog is born is equivalent to one year old of a person.

The life span of a dog is 17 years old one year after birth, 23 years old two years after birth and 28 years old three years after birth according to the calculation method of human life span. After that, four-year conversion will be added every year. So the age of 10 dogs is 55.

The degree of tooth wear in dogs is directly proportional to life span

The dog's age can also be calculated according to the growth of its teeth, the tooth peak, the degree of tooth wear and the appearance color. The dog's teeth are divided into incisors, canine teeth and molars. The teeth of puppies are called deciduous teeth, and the teeth of adult dogs are called permanent teeth. Under normal circumstances, all canine teeth are short crown, the first and second incisors of the upper jaw have three peaks, the middle part has large peaks, the two sides have small peaks, the other incisors have two peaks. The canine teeth are curved, cone-shaped and sharp; the premolars are in three peaks; the molar teeth are in multi peaks for meat cutting, which has the function of cutting food; the canine teeth have the function of biting, which is also a weapon for attack and defense; the molar teeth are divided into the front teeth and the back teeth, which mainly play the role of chewing.

Dog's hair color can be checked for life span

The degree of tooth wear is generally proportional to the age of dogs, but also to the quality of dog food. Therefore, to calculate the physiological stage and the actual age of the dog, the following table can be used. In addition, the age of the dog can also be estimated according to the dynamic changes of the dog hair. 6-month-old puppies began to change their hair; 6-7-year-old adult dogs began to show white hair around their mouth; 10-year-old dogs began to grow white hair on their head and back, the whole body was lack of luster, disordered and had more hair loss.
