The life expectancy of a dog can vary depending on various factors, including breed, build, size, overall health, and human interventions. On average, dogs live between 10 and 13 years.
Smaller dogs tend to live longer than large breeds. For example, Miniature Schnauzers often live beyond 14 years old. Their leading cause of death is heart disease. So, weight control and dental health can help them live longer. There are many breed-specific health conditions that you can watch out for and actively work against.
