They can smell and sense the rise and fall in our feel-good hormones, such as oxytocin, dopamine, and serotonin. When we are ill, these hormones often plummet, and our dogs are usually the first to know it. This might explain why many pets are known to curl up next to a sick or depressed owner.
There have been several other reports since then of dogs detecting cancers by constantly sniffing or nudging an area of their owner's body. Tumours produce volatile organic compounds, which are released into urine, exhaled breath and sweat.
Pups really do know when their humans are having a rough time, and they use a rich variety of signals to figure it out. Not only can your pet tell when you have the sniffles, but domestic dogs have shown an aptitude for detecting both much more minute mood fluctuations and far more serious physical conditions.
Because of their incredible sense of smell, dogs can detect subtle changes in human scent caused by disease. They can smell out illnesses such as cancer. It turns out that cancer and other diseases or infections have a smell. Chemicals called volatile organic compounds are produced by cancer cells.
When dogs sniff people they are gaining all sorts of information about us. They know if we are familiar or a stranger. They know which scents we have attracted while we've been away. They know if we are experiencing changes in hormones, such as those that occur during pregnancy.

Cancer cells, or healthy cells affected by cancer, produce and release these odor signatures." With proper training, dogs have been able to smell cancer in humans' skin, breath, sweat and waste and to alert them.
Summary. Dogs have a highly developed sense of smell, and some can detect the odor signatures of various types of cancer. Dogs have also shown they can detect colon cancer, prostate cancer, breast cancer, and melanoma by sniffing people's skin, bodily fluids, or breath.
It's been shown that dogs have uncanny abilities to detect medical issues, such as cancer, oncoming episodes of medical crisis (such as seizures), or anxiety. There is anecdotal evidence that dogs can also sense death, but how they process and perceive this information is still being debated and researched.
Just as humans stare into the eyes of someone they adore, dogs will stare at their owners to express affection. In fact, mutual staring between humans and dogs releases oxytocin, known as the love hormone. This chemical plays an important role in bonding and boosts feelings of love and trust.

Dogs explore the world with their mouths, and licking is a prime way to gather more information about their surroundings. In some cases, dogs lick because they enjoy the texture or temperature of a surface, such as a window or tile floor.
Research proves that dogs are sensitive to physiological cues that are not obvious to us humans. Such cues include skin temperature and unusual scents. A painful joint with arthritis has increased heat and may emit inflammatory odors; odors that are undetectable to us humans, but scents our dogs can detect.
