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.
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.
Dogs have an extraordinary sense of smell that allows them to detect scents even through barriers like closed containers or clothing. Their noses are highly sensitive and can pick up on odors when they are diluted or masked.
Two, one in each ear, just like humans do.

Dogs can detect odours that humans cannot, as dogs have the ability to detect odours at concentrations 100 million times lower than humans. Infections have a characteristic smell, so yes, dogs can smell infection.
No, dogs cannot see things that are invisible to humans.
because dogs have a better sense of smeel than humans, because there eyesight is poorer than humans there other senses grow
