Dogs typically live on average between 10 and 13 years, though this varies significantly by breed and size

. Smaller breeds such as Chihuahuas, Yorkies, Maltese, and Shih Tzus often live longer, around 14 to 16 years, while medium-sized dogs like Golden Retrievers and French Bulldogs tend to live about 10 to 12 years

. Large and giant breeds, including Great Danes and Saint Bernards, usually have shorter lifespans, often between 7 and 10 years

. The mean age at death for all dogs is about 11 years and 1 month, with dogs dying of natural causes averaging around 12 years and 8 months; only about 8% live beyond 15 years

. Some exceptional cases, like Australian Cattle Dogs, have been known to live over 20 years, with the record held by a dog named Bluey who lived to 29 years and 5 months

. Factors influencing lifespan include genetics, size, living environment, diet, exercise, and veterinary care

. Larger dogs tend to have shorter lives possibly due to faster growth rates and greater organ strain

. Dogs age faster than humans, with the first dog year roughly equivalent to 15 human years, the second year about 9 human years, and subsequent years about 4 to 5 human years

. In summary, dog lifespans vary widely but generally range from 7 to 16 years depending on breed and size, with small breeds living longer and large breeds shorter lives.
