Ohio zoo using beagle to detect bear pregnancies

Elvis, a 2-year-old beagle, sniffs polar bear protein samples at Iron Heart Performance Dog Center in Shawnee, Kan., Monday, Oct. 28, 2013. Confirming pregnancies of the massive bears, a threatened species, has been difficult, and zoo officials say knowing can help make sure they and the Mama bears are ready for birthing and raising cubs.

Zoos around the country will soon find out whether a beagle named Elvis can let them know when their polar bears are pregnant.

The 2-year-old has been specially trained for a year by a Kansas handler who has taught dogs to sniff out everything from explosives to bed bugs.

A Cincinnati Zoo animal conservation scientist had the idea after reading about studies on using dogs to detect cancer. (Associated Press)
