Gone are the days when dogs are only for show, for home purposes, and people’s satisfaction. Dogs, according to several studies, have high intelligence quotient that is why they can be trained.

Training, however, is not the only things we can teach our dogs. Pooches are already being used in the medical field as partners in resolving or detecting some of the most dangerous diseases.

Here are four diseases which our canines can detect in their early stages:


In a study released by United Kingdom-based scientists and researchers, pooches could tell whether a person is infected by malaria by sniffing their used socks.

After training the two Labrador dogs for several months, they were able to correctly identify if a child has been showing symptoms of this disease which is caused by mosquito bites.

Prostate Cancer

Two German Shepherds in 2015 were trained by Italian researchers to detect chemicals linked to prostate cancer using sample urines. These two dogs’ accuracy in telling whether the urine showed symptoms of such disease is 90 percent most of the time.


One of the common diseases unhealthy people have is diabetes. Recent research used dogs to detect whether a person has high blood sugar levels.

The charity which is called Hypo Hounds is now training dogs to sniff whether there is a change in their owner’s sweat or breath odor. The dogs are successful in detecting early signs of sugar increase than glucose monitoring machines.

Parkinson’s disease

A research done by scientists from Manchester University suggested that dogs are highly trainable in detecting early stages of Parkinson’s disease even years ahead before its symptoms show up.

The researchers are now studying the possibility of dogs as a detector of Parkinson’s using their sense of smell.

According to them, they were inspired by similar research done in the past where dogs were able to tell if a person has a high sugar level or not.
