This giant hound has 300 million scent receptors — more than any other breed. They are famed for their man-trailing abilities and are so reliable their evidence is admitted in court. Bloodhounds can not only follow a scent on the ground, but they can also air scent.
Scientists report that a dog's sense of smell is 10,000 to 100,000 times more acute than a human's. One of the reasons a dog has a much better smelling ability than we do has to do with the number of scent receptors: For every scent receptor a human has, a dog has about 50.
The Kangal is a large, muscular dog that typically weighs between 100 and 130 pounds. They have been trained to guard sheep and other flocks against giant predators such as wolves, jackals, and bears. The Kangal has a mighty bite, with a bite force of 743 PSI. It is the highest bite force of any dog breed.
For dogs, citrus scents are the enemy. Citrus scents like lemon, lime, oranges, and grapefruit–especially in high concentrations often found in household cleaners or essential oils–can cause irritation to your pup's respiratory tract, so keep any fresh citrus fruits out of your dog's reach. You know–just in case.
Key takeaway. Dogs sniff people's crotches because of the sweat glands, also known as apocrine glands, that are located there. Sniffing these glands gives a dog information about a person such as their age, sex, mood, and mating probability.
Dogs choose their favorite people based on positive interactions and socialization they have shared in the past. Like humans, dogs are especially impressionable as their brains develop, so puppies up to 6 months old are in their key socialization period.

#1 Kangal. With an almost unbelievable bite force of 734 psi, the Kangal doubtless has the strongest jaws in the world. Bred in Turkey to bring down larger animals preying on sheep and other livestock, these pups are masters at neutralizing danger!
Labrador Retrievers, Cavalier King Charles Spaniels and Newfoundlands are among the safest dog breeds that are least likely to bite, new research has found. While any dog can nip, these breeds are known for their particularly sweet-tempered spirit as long as they are treated right.
Research has shown that dogs can literally smell things like stress in humans. Changes associated with death occur months before the event takes place. These changes can affect subtle differences in the smell of a person or another animal, an indicator that death is near.
On this note, research shows that dogs can sense depression, and many of them even respond lovingly to their humans in an attempt to cheer them up. In the same way that we pay attention to their behavior, dogs also pay attention to our actions to determine our “energy” that day.
The science is in, and the answer is a resounding YES—dogs can smell fear. Dogs have olfactory superpowers that can detect a human's emotional state by the scent that a human emits. That's right—you can't hide fear from dogs.
Our dogs know our smell, and they love it. New scientific research proves that your fragrance is your dog's favorite. Neuroscientist Gregory Berns and his team at Emory University's Center for Neuropolicy used advanced brain-imaging to demonstrate dogs recognize scents even when the source isn't present.
How far a dog smells depends on conditions such as wind and type of scent, but they have been reported to smell objects and people over 12 miles away. Dogs' olfactory systems work so well that they can be trained to pick up odors as little as a pictogram which is a trillionth of a gram.
Under perfect conditions, they have been reported to smell objects or people as far as 20km away. You might be interested to know dogs are not the only great smellers.
