Canine sense of smell could help diagnose disease
The next time your dog decides to dive belly first into a pile of rotting fish or writhe in ecstasy in another dog’s feces, keep in mind that this seemingly horrifying urge could one day help save your life.
Dogs have long been used to sniff out explosives and drugs, track criminals and find missing children. Now, researchers are attempting to harness the olfactory powers of canines for use in the field of medicine.
Scientists are training dogs in the hopes that they may one day be able to reliably diagnose certain forms of cancer by smell, and help doctors catch these diseases earlier than conventional diagnostic tools currently allow.
Already dogs are used to warn of epileptic seizures, low blood sugar and heart attacks, although whether they are detecting changes in smell or physical behavior is still unknown. And, while they may not be able to perform CPR or operate a cardiac defibrillator (at least not yet), some canines do know how to call 911.
