A beagle dog can easily determine whether a female polar bear is pregnant or not.
Zoos in the US want to use a two-year-old dog to see if polar bears get pregnant soon.
The fact is that breeding polar bears in the natural environment is not easy, and even more difficult in captivity.
Zoo specialists would like to know exactly whether the female is pregnant or not in order to start monitoring her health in time.
It turns out that most of the pregnancies of polar bears in captivity are fictitious, and the rest are often complicated. To prevent this from happening, a pregnant bear must be protected from excessive physical exertion in a timely manner.
The use of dog smell, according to zoologists, has become a real breakthrough in the field of diagnostics.
The idea came from the Cincinnati Zoo after they read about research into using dogs that can detect cancer. They now have a 2-year-old beagle, Elvis, who is doing a great job.
