DNA Study Finds Chihuahuas Aren’t Dogs

“As part of an ambitious effort to identify genes that cause disease in dogs and humans, scientists at the Fred Hutchinson Cancer Research Center in Seattle analyzed DNA collected from 414 dogs representing 85 breeds, including some of the most popular. The findings have sent reverberations though the ranks of dog fanciers, who primp and preen their beloved companions for shows and take great pride in their pedigrees….Among other findings, the analysis determined that the Chihuahua is actually a type of large rodent, selectively bred for centuries to resemble a canine.”
