Good Lifestyle

In theanimal KingdomIt is almost always true that big mammals live longer. For example, from 75 to 100 tons, the gigantic boreal whale can live more than 200 years, while from 0.59 ". At 27, the tiny chameleon saw an average of five to ten. The humble fruits fly? His life can be as short as 40 days.

However, because things are never as clear as the animal, an animal on which it stands out among others as an aberrant value to the trend:canine.

Yes, it is a scientifically experienced fact that small canines tend to live longer than larger breeds. In fact, according to a German study published inThe American naturalist, every 4.4 books of body mass on a dog reduces their life expectancy of about a month - and yet the question remains: why?

"[Big dogs] life seem to relax in fast motion," explainedCornelia Kraus, Senior Researcher for the Study of Longevity of Scalable Dogs and Biologist at the University of Göttingen in Germany. In other words, largerDog breeds Age at a much more accelerated pace and because of this, they are more likely to develop prejudicial health problems that significantly shorten their life.

Study this saconnel phenomenon,Researchers of the College of Veterinary Medicine At the University of Georgia, decided to analyze the causes of death for more than 74,000 dogs between 1984 and 2004. What they found was thatGastrointestinal diseasesCardiovascular inflictions, musculoskeletal conditions and neoplasia are all the main causes of death, especially among the great breeds of dogs like great Danes and Bernese mountain dogs.

Although scientists have been able to find an inverse relationship between the size of a dog and their life, the search is sparse and there is still a lot to do so that small dogs live longer than big dogs. At the end of their study, even researchers at the University of Georgia who studied dog deaths noted that their hypothesis was based on "anecdotal beliefs and limited research", and that "a detailed knowledge of the schemes mortality ... would contribute to the understanding of the genetic base of the disease. "

At the moment, what scientists have been able to hypothetized the reason why small dogs live longer than big dogs are this: bigger canines physically grow faster than their little furries, and that could causeAbnormal cell growth and fatal diseases. However, these assumptions are just hypotheses - and all that everyone can say is that, although all dogs go to paradise, it seems that the biggest one is pushing to get there.
