6 Medical Conditions Dogs Can Sense


To understand why dogs are so incredibly gifted at sniffing out medical conditions (not to mention drugs, explosives, lost humans, and, of course, cats) you have to fully appreciate the wonder of the canine nose. Your average family dog has a sense of smell 10,000 to 100,000 times more sensitive than any human. They have 300 million olfactory receptors to our measly 6 million. Scientists have likened their ability to “catching a whiff of one rotten apple in two million barrels.”

And these facts just barely scratch the surface of what dogs’ remarkable snouts are capable of. From law enforcement and military employment to laboratory medical research, the power of the canine nose has helped save countless human lives.

Dogs all over the world are currently putting their noses to use detecting these 6 medical conditions in humans. In doing so, they improve and prolong the lives of the people they serve.

1. Cancer 

The working dogs of the non-profit In Situ Foundation have the ability to sense early stage cancer in small samples of human urine, saliva or expelled breath with more accuracy than any modern equipment. The 50+ dogs trained by In Situ founder, Dina Zaphiris can sense multiple types of cancer in parts per trillion – similar to sensing a single drop of blood in an Olympic-sized swimming pool.

While my mom is away, I wanted to remind you to keep voting for me, Stewie, so I can continue to detect cancer in humans…

2. Seizures

There is some controversy surrounding whether or not dogs can actually sense an impending seizure, or just react to one in progress. If they do sense them coming, scientists have not yet figured out how. Since no specific scent or marker for predicting seizures has been identified, trainers are only able to teach service dogs to help out during and after an attack. It is unknown whether those dogs that do seem to sense a seizure before it hits are picking up on a smell brought on by a change in body chemistry or subtle behavioral changes.

This sweet thing knew his girl was about to have a seizure. I am so unbelievably blessed to have this amazing boy…
