Pheromones are naturally occurring chemicals excreted by animals and humans alike. Although the usefulness of human pheromones is much reduced because of modern hygiene practices, they are produced by all humans.
Yes, a dog's sense of smell is estimated to be between 10,000 to 100,000 times more sensitive than that of a human. This heightened sense of smell allows dogs to detect scents at incredibly low concentrations and from long distances.
Two, one in each ear, just like humans do.
Yes. Dogs have a very highly developed sense of smell - more highly developed than any other of their senses. Dogs can actually smell several layers of chemicals simultaneously, which is why they are so effective in sensing drugs on people, and there is plenty of evidence to suggest they can also sniff out diseases. Dogs have over 220 million olfactory (smell) receptors in their noses. This is in comparison to humans and their mere 5 million receptors.

Dogs can smell a million times better than humans--so smelling is to dogs as seeing is to humans. In many ways, dogs "see" their world by smell using their noses. So sniffing their surroundings is the main way they perceive the world.
Certainly yes. Dogs have a keen sense of smell that is much better than humans.
Dogs have the best noses, followed by cats. Humans occupy a distant 3rd place in the "by a nose" category.
