Why don’t dogs live as long as people?
Generally speaking, the smaller the **mammal,** the faster the metabolism. That means higher body temperatures, and faster heart rates, respiration, and aging. To give you some other animals for comparison: a mouse will die of old age at around 1 year.
The Short Answer
Generally speaking, the smaller the **mammal,** the faster the metabolism. That means higher body temperatures, and faster heart rates, respiration, and aging. To give you some other animals for comparison: a mouse will die of old age at around 1 year. A rat, 3-5 years. Horses: 25-30 years; elephants: 50-70 years. *There are some giant breeds of dog, but they tend to have shorter lifespans than others; largely, their hearts can't take the burden of the oversized body. The way we get dogs of unusual shape or size is through generations of inbreeding, which comes with crappy outcomes for the individual animals. As far as I know, there isn't a single huge or tiny breed of dog that doesn't have a genetic tendency towards one or more serious health issues. *Edited again for clarity.
