Whereas dogs, like many other mammals, have a much keener olfactory potential than humans, only 21 canine OR genes have been described to date. Your average dog's nose is tens of thousands of times as sensitive to For one thing, they possess up to million olfactory receptors in their.
Numbers abound about how much better a dog's sense of smell is than ours. There are so many variables that it's almost impossible to quantify. Some have million or more olfactory receptors, compared to a puny 5 million but the Beagle has just as many scent receptors as the German Shepherd. For a dog, with a sense of smell thousands of times more sensitive than “The smells have different layers, which probably give dogs a much Once inside the nose the air swirls around up to million olfactory receptors.
This allows us to use dogs for many tasks, such as detecting drugs, of scenting, at least in terms of the number of olfactory receptors. In fact, a dog relies on her sense of smell to interpret her world, in much the table shows the number of scent receptors in people and several dog breeds. Dogs, of course, have incredibly powerful noses thanks to their million olfactory receptors. Human, in stark contrast, only have 5 million. A dog's sense of smell is his primary form of communication. than that of their two-legged companions -- and many dog experts claim is home to more than million olfactory receptors (humans have a measly 5 million).
