What Factors Affect a Dog’s Lifespan?
A dog’s lifespan is influenced by various factors, including living environment, diet quality, medical care, and breed characteristics. Generally, small dogs can live up to around 15 years in a well-maintained household with regular medical care. In contrast, large dogs, under stable living conditions, typically have a lifespan of 11 to 12 years.
If a dog has a stable living environment, a balanced and healthy diet, and access to quality medical care, it can live up to 18 or 19 years. However, for stray dogs, due to harsh living conditions, food shortages, and a lack of timely medical treatment, their average lifespan is often only 4 to 6 years.
