The dog has a particularly good sense of smell. Scientists are now investigating dog's olfactory ability as a more reliable method of detecting human disease than traditional tests.
Several studies have been conducted on the ability of dogs to smell diseases. Dogs participating in this study produced better results than medical tests. The dog has a special smell called the Jacobson organ which is important for detecting body odor. As a result, even physicians can find diseases that they do not recognize at first. Dogs can easily detect very minor changes in the human body. Researchers and dog breeders expect that using these traits of dogs can be of considerable help.
During the past two decades, researchers have analyzed the possibility of detecting cancers in dogs. Studies have shown that dogs can successfully distinguish cancer patients from non-cancer patients through training.
Furthermore, the type of cancer could be recognized. In one study, five trained dogs detected 88% of breast cancer and 99% of lung cancer with only human breathing.
The UK's National Health Insurance Corporation is training dogs that can detect breast cancer. It is an assessment that dogs can be diagnosed easily if they can identify the type of cancer by simply breathing women.
Other studies have shown that dogs can detect melanoma, a deadly skin cancer. This is because the urine of the patient and the smell of the blood sample have changed. In addition, there was a significant success rate in the detection of prostate cancer using urine. Prostate cancer test dogs performed better than prostate-specific antigen (PSA) tests.
After constant research, the dog confirmed that it could detect cancer in humans, but physicians who used cancer-detecting dogs had to undergo annual checkups. The researchers still do not know exactly which compounds the dogs are reacting to, so this problem appears to be an obstacle to cancer detection dog training.
Hypoglycemia can be dangerous to people with type 1 diabetes. Dogs, however, can detect hypoglycaemia with a person's breathing odor. Can Do Canines, a nonprofit organization, is training dogs to smell a sudden drop in blood sugar.
According to one study, dogs can detect isoprene. Isoprine is a natural compound that occurs when a person breathes, and increases rapidly when blood sugar is low. People can not recognize this chemical, but dogs can respond sensitively.
Diabetic dogs are trained to observe people and notify them when their isoprenaline levels change. And these dogs always wear special backpacks that contain the owner's medical information, sugar, and emergency contacts.
A patient with epilepsy does not know when to attack, but the dog knows. According to Canine Partners For Life (CPL), located near Pennsylvania, some dogs are inherently capable of detecting seizures imminent. Therefore, training dogs with these abilities can cause the owner to wander or bark around when the seizure is near. Through this process, the patient can prepare to lie down or leave a lot of people.
A team of researchers has provided evidence that dogs can smell human socks and identify malaria. After several months of training, Labrador and Labrador retrievers were able to detect malaria infection with relatively high accuracy.
Manchester University researchers have trained their dogs so they can detect it before the symptoms of Parkinson's disease appear. The dogs diagnosed Parkinson 's disease six years ago with the pre - patient body odor.
