Nearly 40% of small breed dogs live longer than 10 years, but only 13% of giant breed dogs live that long. The biologists at Germany’s University of Göttingen analyzed data on over 56,000 dogs representing 74 breeds and concluded that every increase in 4.4 pounds (2 kg) reduces life expectancy by approximately one month.
