Beagle Tries To Determine If Denver Polar Bear Is Pregnant
DENVER (CBS4) - The Denver Zoo is anxiously waiting to find out if they are expecting a baby polar bear, and they are counting on a beagle to make the diagnosis.
Zookeepers believe 11-year-old Cranbeary may be pregnant.
She's one of 17 polar bears around the nation that mated this spring and could be pregnant.
But it's really tough to tell if a polar bear is expecting.
Samples of their feces have been sent to Cincinnati Zoo. That's where Elvis, the dog, is hard at work sniffing the samples.
Earlier this year zookeepers started giving Elvis special training to determine if polar bears are pregnant. This is the first time sniffer dogs have been used in this kind of research in any wildlife species.
Elvis will be testing and double testing all the samples in the next two weeks.
