The life span of dogs is the same as that of people. In general, its life span is different. Because it is influenced by daily nutritional status, living environment and epidemic prevention and control conditions. However, according to long-term experience, the life span of a dog can be roughly calculated as follows: the first year of a dog is equivalent to the life span of a person 10 year, and the next year is equivalent to the life span of a person of 6-7 years. In other words, dogs live to 10 years old, which is equivalent to people living to 70 years old. So generally speaking, the life span of a dog is about 13 years old. Under the management of modern Russian science and technology, the life span of dogs has been improved to varying degrees. Some live for 20 years, and some dogs live to be 30 years old.
The overall figure also has a certain relationship with life expectancy. Generally speaking, the smaller the figure, the longer the life span. Because physiologically speaking, the metabolism of large dogs is faster than that of small dogs, and the cardiopulmonary burden is also relatively large. At the same time, large dogs are generally not as resistant to diseases as small dogs. So in general, Chihuahua's life span is about 15 to 18 years.
