HOW DOGS CAN SAVE LIVES!!

researchers at the Pine Street Foundation in California trained dogs to sniff out both breast and lung cancer.
Rather than sniffing urine samples, however, the dogs smelled breath samples from the patients. The results were startling -- they had an 88 percent success rate with breast cancer and a 97 percent accuracy rate with lung cancer. The most impressive study took place early in 2011, in which dogs in Japan detected colorectal cancer with 98 percent accuracy by sniffing breath samples. This is more accurate that the traditional diagnostic tests for the disease.

So far, the cancer-sniffing dog phenomenon has only been used in research, but scientists are hoping to identify and isolate the exact compounds dogs are detecting to create electronic cancer-sniffing devices

Imagine that instead of giving a urine sample or getting blood drawn when you need a diagnostic health test, you consult with a dog instead. It's a funny concept, but your pooch may have more in common with your doctor than you previously thought. We've long known that dogs have stronger senses than we do, with their sense of smell getting the most attention. That sense of smell is about 1 million times greater than ours, which is why they've been used in tracking and hunting since they became our companion animals. Today, dogs help us find everything from bombs to drugs, and it's simply amazing what they can do. In addition to smell, many dogs also have a strong "sixth sense"; they just notice things that we don't.  

Dogs have also saved lives by alerting people to health problems before they even occur. Alert dogs let their type 1 diabetic human companions know that their blood sugar levels are off before the person feels any symptoms or takes a blood test. Low blood sugar changes the volatile organic compounds emitted through the pores of a diabetic; the dogs let their owners know of this change by whining or licking their hands. Dogs have also alerted humans to changes in their blood pressure or even let them know when a heart attack was imminent.
