Man's best friends - dogs, have been our companions for millennia. They have been with us since the dawn of humanity We have intertwined our common paths so much that somehow we cannot imagine our existence without the company of four-legged us lovers
They are not only our friends but also helpers Labradors andretrievers have recently been increasingly used as guide dogs , assistants to blind people, sanbernares – asmountain rescuers, Newfoundland dogs are great water rescuers, and German Shepherds– flawless cops!
Recent studies show that dogs can be useful in another very important direction – early detection of cancer. It turns out that the accuracy of the dog's nose in this regard is up to 98%.
Two 3-year-old female German Shepherds were trained at the Veterinary Center of the Italian Ministry of Defense in the recognition of specific volatile organic compounds released by prostate cancer.
The dogs analyzed more than 400 urine samples, with one dog detecting prostate cancer among the samples with 100% accuracy and the other with 98% accuracy. Prostate cancer isn't the only cancer that dogs feel. Our friends successfully detect breast, ovarian, colon, bladder, skin, lung cancer usually by smelling the samples.
Cancer causes the release of specific odors from the human body and excrement, which are recognizable only to the much more sensitive canine nose. Dogs have 220 million olfactory cells in their noses, while humans only have 50 million
In addition to laboratory studies on how dogs are able to detect cancer, there are also witness accounts of people whose animals are felt in some way the change in their bodies or their loved ones.
Many owners tell how their dogs persistently sniffed or pushed the part of the body where it later turned out to have a tumor. The peculiar behavior of these smart and pure-hearted balls of fluff should never be overlooked! Maybe they are trying to save their beloved masters!
