The estimated life span of a dog is determined by many factors such as body size , lifestyle , weather and nutrients .
Body size , the larger the size of the dog 's body so his age is getting shorter , the smaller the size of the age of the dog 's body will be getting longer . For example , the Great Dane who has a very large size of the average can only survive until the age of 8, while the annual Chihuahua dog that has a very small size can last up to 13 years of age .
Lifestyle , a dog whose life is always stressful because grounded or not maintained according to its function will be shorter then his age . Beagle is intended for hunting , kept in a small house and always grounded the level of all his stress will be very high . If you want your dog to live longer , keep it according to its function .
The weather , lots of dogs that are kept in climate such undue Siberian Husky dogs that have thick fur maintained in countries with tropical climates . Many cases of woolly dog dying because of the heat ( Over heat ) in a tropical country . Even if the dog could be saved , organs such as the brain must also have decreased function as a result of this over-heat attack . Therefore , even if you have thick shaggy dog to adapt to the weather in the tropics , do not notice until it was placed in the heat .
Nutrition , dogs are not given enough nutrients properly and then of course his health will also decrease . Conversely , given the breed with excessive nutrients will also be short lived because the organs are working very hard to digest excess nutrients provided . By the time the dog is still alive in the wild forest , much shorter than the age of the dogs that are kept at home because they are living wild in the woods does not receive enough nutrients and also more susceptible to disease .
