Beagle will sniff out polar bear pregnancy
A beagle named Elvis will determine whether one of the Denver Zoo's polar bears is pregnant. "This is the first time sniffer dogs have been used in biomedical research as it relates to any wildlife species, making this project truly one-of-a-kind," said Dr. Erin Curry in a statement. According to a press release by the Denver Zoo, Elvis' nose is nearly as accurate in determining pregnancy from poop samples as an over-the-counter human pregnancy test. After a little less than one year of training, Elvis has demonstrated about 97 percent accuracy with more than 200 samples from pregnant females.
