- The structure of a dog's nose gives it a sense of smell that is thousands of times better than a human being's. A dog's nose has two hundred million nasal olfactory receptors. Each receptor detects and identifies the minute odor molecules that are constantly flying off different objects. Of all a dog's senses, its sense of smell is the most highly developed. Dogs have about 25 times more olfactory (smell) receptors than humans do. These receptors occur in special sniffing cells deep in a dog's snout and are what allow a dog to "out-smell" humans. Dogs can sense odors at concentrations nearly 100 million times lower than humans can. They can detect one drop of blood in five quarts of water! Sniffing the bare sidewalk may seem crazy, but it yields a wealth of information to your dog, whether it's the scent of the poodle next door or a whiff of the bacon sandwich someone dropped last week.
- When a dog breathes normally, air doesn't pass directly over the smell receptors. But when the dog takes a deep sniff, the air travels all the way to the smell receptors, near the back of the dog's snout. So for a dog, sniffing is a big part of smelling.
- "Generally" dogs have an olfactory sense approximately 100,000 to 1,000,000 times more acute than a human's. A Bloodhound, (The dog with the highest sense of smell) has a 10,000,000 to 100,000,000 higher ability than a human.
- Wild canines rely on smell for hunting. They also use smell to decode scent messages left by other animals -- friend or foe, predator or prey. A wild canine's sense of smell is especially important in habitats where seeing prey is difficult such as the thick underbrush of forestsre at home: sniffing dogs
- A dog can sniff out all sorts of smells that human noses miss. Because of this keen sense of smell, we can train them for jobs such as tracking, rescue, or drug and bomb detection and to detect a wide variety of specific scents, such as drugs, fruits or the feces of particular animals. Dogs that make a living by sniffing are trained to alert their handlers to the presence of these things by pawing, barking, or in the case of something dangerous, sitting quietly. They are trained by the promise of a favorite toy or play time each time they successfully sniff out the target scent.

Thanks for the feedback!
There is no specific number that I know of that describes how much "better" a dogs hearing is to humans. Dogs can hear better 1. because of the shape of their ears (larg…er and more cup-shaped than humans) and the muscles that allow the dogs ears to twist and turn to catch sounds, and 2. because dogs have a much higher range of hearing than humans. The typical human can hear anything between 20 Hz to 20,000 Hz, while the typical dog can hear anything from 40 Hz to 60,000 Hz!
I'm not sure how much but they're remarkable hearing devices, far more sensitive than our ears and capable of hearing at a higher frequency.
They have way more olfactory receptors than we do.
actually a dog can hear 24 times better than us humans can.thats why there afraid of thunder.
Yes of course!
You know how dogs can hear a dog whistle and humans can't because its to high pitched? That much better. Think about it:]
According to the American Kennel Club: A dog's sense of smell is 100,000 times stronger than a human's. It is said that dogs have 2 billion olfactory receptors, versus 4…0 million in humans.
The dogs have no glands. That's why they can't smell.
because dogs have a better sense of smeel than humans, because there eyesight is poorer than humans there other senses grow
88 times more
Scent and hearing are the main senses that dog actually have. Their eyesight isn't that good, and they have no sense of taste, smelling is how they decide if a food is good or… not,because they do not possess taste buds Answer:Smells are detected by specialized nerve endings called "olfactory receptors." On average, dogs' noses have about 40 TIMES more of these receptors than human noses.
They can otherwise why would a sequrity guard or a police use it.
they have their sense of smell 14 times better than humans. they can detect stuff and they can help you find things if they are trained.
This is all a matter of opinion, but if you'd like mine, I'd say dog smell is literally 1000 times better than people smell.
They have more smell receptors than humans.
