Large dogs live less than little, because faster aging Bashny.Net

Typically, large mammals live longer than small ones. For example, elephants in the wild live to be 70 years old, and domestic mice live up to a maximum of four years. But within the same species, it seems the opposite is true - the big mouse, horse, and perhaps even the people live on less.

Consider the example of dogs. Over the past millennia, people have brought a number of different species, the size of a coffee cup to the calf. The most severe in the history of the dog was an English Mastiff Zorba, weighing 155 kg, and the smallest dog is still alive - a terrier Maisie weighing only 110 g



Large breeds more likely to die young, for example, dog weighing 70 kg on average, live seven years, while the life of a poodle - up to 14 years.

The researchers analyzed age at death for 74-breeds using data from veterinary clinics of 56,000 dogs. It was found that the aging process takes place in the large rocks will - on average two kg weight mean minus one month of life. In addition, owners of large canines more likely to die from cancer, possibly associated with abnormal cell growth.
