How long does a dog live?

If they do not suffer any disease or injury, dogs can generally live for about 10-15 years, but this also has a lot to do with the dog's size, breed, genetics, diet, etc., such as the lifespan of small and medium-sized dogs Most of them are relatively long, usually 14-15 years. Due to their large size, large dogs have a heavy burden on their organs, so they age faster, with an average lifespan of about 10 years.
