How long is the longest life span of a dog in the world

29 years old. It was only published in the newspaper a few days ago that the world's oldest dog had died.

There are many factors that affect the lifespan of a dog. For example: pedigree, breed, environment, hygiene, exercise, eating habits and feeding management The longest-lived dog I have ever seen is more than 17 years old. Huh

Ten years or so, how to calculate the life span of a dog:

The age of a dog is equivalent to 17 years after birth, 23 years after two years of birth, and 28 years after 3 years of birth. After that, four years are added for each year that passes. Therefore, the age of 10 dogs is 55 years old, and recently because of the improvement of nutrition, the life span of dogs has also been extended, and some dogs will live for 20 years.

The lifespan of dogs is often due to different dog breeds, and there are different results, dogs and people are different in that the time after old age is very short, and before the death of half a year, dogs can still live a very healthy life.

15 to 20 years, but there are exceptions.

The longest-lived dog in the world is the Tibetan mastiff. Tibetan mastiff: The average lifespan of a Tibetan mastiff is about 20 years, so it has the highest lifespan among all dogs.

Australian Cattle Dog: This breed of dog mainly guides cattle and can live up to 16-20 years. Chihuahuas: Chihuahuas are the smallest dog breed in the world with an average lifespan of 17-18 years, with an average lifespan of 17-18 years.

Teddy Dog: It is a type of poodle with an average lifespan of 16-17 years. Dachshund: Dachshund is a dog that does not rely on appearance, and the lifespan of the dachshund can basically reach 16-18 years.

The longest-lived dog in the world is the Australian Cattle Dog.

The Guinness World Record for a dog's longevity is held by a dog named Bluey, a breed of Australian Cattle Dog, who was born in 1910 and died in 1939 at the age of 29.

The Australian Cattle Dog is an intelligent and independent dog breed, and raising it to live with it requires certain challenges. It is known for its stubborn temper, but to put it another way, when it is determined, it does not give up. The Australian Cattle Dog is suspicious of strangers, which makes it an excellent watchdog and will also exhibit guard behavior when necessary.

The lifespan of a dog is related to a variety of factors

The life span of the dog is closely related to the breed, physical fitness, living environment, eating habits and genetic factors, etc., if the breeding environment is good, the dog loves to exercise, and the dog is healthy will have a longer lifespan, and the life span of the more tired working dog will be shorter.

Dogs grow at a relatively fast rate. A week of a dog is equivalent to 1 month of a person, and a dog reaches adulthood at the age of 1, which is equivalent to 18 years of age, and 3 years after birth is its prime of life, which is quite 28 years old. After that, four years are added for each year that passes.

Dogs generally enter middle age at about 5 years old, which is equivalent to about 40 years old for humans. At the age of 10, they begin to enter the old age, which is equivalent to 60 to 65 years old for humans. When the dog enters old age, it is necessary to take more care of the dog.

The lifespan of a dog is about 13 years, and the age of 16 is equivalent to a person over 96 years old.
