Meet the Dogs That Can Sniff Out Cancer

author2023.04.12

Osa, an athletic 62-pound German shepherd with a long fluffy tail and a fondness for red bandannas, seems an unlikely superhero.

She chews on the couch when she’s bored and isn’t above making a scene to get attention. On a recent day when her foster mother and trainer Anne­marie DeAngelo stepped outside their New Jersey home while chatting with a visitor, Osa bounded up and barked for attention; when that failed, she leaped onto the patio table, stuck her snout in DeAngelo’s face, and began whining.

“You are unbelievable,” DeAngelo growled before cracking a smile.

But if Osa wants to play the diva, she’s entitled. After all, how many six-year-old pooches do you know who have mastered the art of sniffing out cancerous tumors and are involved in a research project that has the potential to revolutionize oncology?
