This dog sniffed out her owner’s ovarian cancer

Something that makes ovarian cancer so dangerous is that it’s often not diagnosed until it’s spread to other organs. But try telling that to a rescue pup insistent on saving his person’s life. Hazel MacDonnell had noticed Bob, a border collie, seemed out of sorts back in December 2015.

But it turned out it wasn’t Bob’s health that Bob was worried about. When Bob finally started jumping on and hitting Macdonnell in the stomach, she got the message and booked an appointment with her internist, which appointment ultimately led to a diagnosis of early-stage ovarian cancer three months later.
