What is the life expectancy of a dog? - briefly

What is the life expectancy of a dog? - in detail
The life expectancy of dogs varies significantly based on several factors, including breed, size, genetics, lifestyle, and overall health. On average, smaller breeds tend to live longer than larger ones. For example, the average lifespan of a Chihuahua can exceed 15 years, while that of a Great Dane is typically around 8-10 years.
Genetic predisposition also plays a crucial role in determining longevity. Certain breeds are more susceptible to hereditary conditions that can shorten their lifespan. Regular veterinary care, a balanced diet, and appropriate exercise can help mitigate these genetic risks and extend the dog's life.
Lifestyle factors such as obesity, lack of exercise, and inadequate mental stimulation can also negatively impact a dog's longevity. Spaying or neutering a dog has been shown to increase its lifespan by reducing the risk of certain diseases and cancers. Additionally, regular dental care can prevent oral health issues that might otherwise shorten a dog's life.
Overall, while there is no definitive answer to how long a dog will live, responsible pet ownership, which includes providing a healthy lifestyle and regular veterinary check-ups, can significantly improve the chances of a dog living a longer, happier life.
