To close out this week’s celebration of the dog days of summer, we return to a story that highlights the remarkable talents of the dogs at Penn Vet’s Working Dog Center. A study led by veterinarian Cynthia M. Otto and postdoctoral research fellow Clara Wilson has shown that hemangiosarcoma, an aggressive cancer of blood vessel cells in dogs, has a distinct “signature” scent that trained dogs can detect.
Often described as a “silent killer,” hemangiosarcoma frequently goes undiagnosed until a dog that appears healthy suddenly collapses. These findings offer the hope of a better screening tool and more effective treatments.
“If we can detect it early, maybe we could prevent it from spreading because it’s the spread that’s really devastating,” says Otto.
