Signs of Dogs Smelling
Dogs have an impeccable sense of smell. Some breeds can smell up to 100 million times more than humans. No matter the breed, dogs definitely have a very powerful sense of smell. You'll certainly notice that your dog is smelling something especially interesting when he becomes more alert. He may put his nose in the air in order to pick up more scents. This will guide your dog in making a decision about whether or not to pursue the scent or let it pass.
If your dog smells something unusual and feels threatened, he may go hide in a safe place until he is sure the area is safe. Sometimes he may hide behind his owner and cower if he is feeling fearful. A dog can tell when people are scared because they can smell the production of sweat coming from the nervous person. Depending on a dog's breed and personality, he will react differently. Some dogs may not respond well and may become standoffish. Other dogs will comfort the scared person to assure them that all is well.
Dogs are naturally great smellers. They can sometimes detect a change when a woman becomes pregnant, and they can pick out specific scents that may seem like just one scent to a human. For example, when a human smells stew, they just smell stew. But when a dog smells stew, he smells all of the individual scents in the stew.

History of Dogs Smell
There really isn't anything a dog can't smell!The dogs we know and love today evolved over thousands and thousands of years. Originally, wolves and humans formed a bond. It was 15,000 years ago when wolves and humans began their friendship. Wolves helped humans hunt and they detected potential predators. In turn, humans gave the wolves their leftover food and provided protection against dangerous threats. Over the next thousands of years, wolves evolved into dogs. And eventually, we wound up with more dog breeds than we can count! Puppies warm our hearts with their four, furry paws and their sweet, puppy-dog eyes.
Wolves have a keen sense of smell. That's why they were so helpful to hunting humans. This sense of smell is something that was continually passed down to each generation of offspring. Dogs today have an excellent sense of smell, which is still helpful to humans in many ways.
