The life span of dogs varies with breeds, heredity, diet, living environment, medical care, health management and other factors. Generally speaking, the life span of dogs is about 10- 15 years, but some dogs can live longer, even more than 20 years.
First of all, breed is an important factor affecting the life of dogs. Large dogs are usually more likely to get sick than small dogs, and their life expectancy is usually shorter. Small dogs are usually healthier and live longer than large dogs.
Heredity is also one of the important factors that affect the life span of dogs. Some breeds of dogs are naturally prone to illness, while others are healthier and live longer.
Diet and living environment will also affect the life span of dogs. A good diet and living environment can ensure that the nutritional needs of dogs are met, and at the same time, dogs can be prevented from contacting harmful substances and pollutants.
Health care and health management are also important factors that affect the life span of dogs. Taking the dog to the vet for health check-up regularly, dealing with diseases and health problems in time, and maintaining the dog's physical and mental health are all helpful to prolong the dog's life.
