Dogs are faithful and sensitive animals. So much so that they are capable of doing the unimaginable for their owners. Sierra is a husky dog who has become famous after detecting a tumor in her owner, Stephanie Herfel. Although Sierra had not received any training, he was able to guess that something bad was happening to its owner.
Although many dogs are already being trained to detect diseases, it is now being investigated to what extent they are capable of discovering tumors or cancer.
The dog came into Herfel’s life as a 9-month-old puppy and just as his son was posted to the Air Force. As the Journal Sentinel reports, the dog began to sniff her owner’s abdomen insistently, so much so that she even thought something had been spilled there. Afterward, Sierra hid in the closet as if she had been scared.
After the strange behavior of the dog, Herfel decided to go to the emergency room. There they told him he had an ovarian cyst. However, Sierra was still hiding in the closet and she had abdominal pain, so she decided to repeat the medical appointment with a gynecologist. This time he was diagnosed with stage 3 ovarian cancer.
Sierra had done well to care for her owner. In fact, the dog detected tumors in Herfel’s body up to two more times and even detected a tumor in a friend of hers, as he published on his Facebook account. Although cancer is a disease that tends to come back, Herfel remains very optimistic. He has by his side the most faithful and protective dog!
Animals give us the most unconditional love and, sometimes, they manage to save our lives. Now it is being investigated if there are more dogs like Sierra around the world.
