Dogs have incredible senses; they can hear any little noise and smell a mile away. People talk about opening a package on a piece of cheese; you don’t hear anything when you open it, but your furry friend can and comes running.

The senses of dogs are so much sharper than those of humans. How many times have you had your windows open, sleeping soundly, and the dogs barked and you look to see the raccoons are at bird feeders. You didn’t hear or smell them, but your canine companion did.
A dog’s senses are very similar to ours, but not. Here are their five senses according to Alexandra Sifferlin from the Times Special Edition article, How Dogs Think: Inside the Canine Mind.
To touch
The sense of touch is used immediately at birth when puppies are cleaned by their mother using licks and snouts, which can register with them like a hug does for a human.
A dog’s paws contain nerve endings that can help him navigate his movements.
The dog’s muzzle is rich in nerve endings, so the nose serves both an olfactory and tactile exploratory function, Sifferlin explains.
Seen
A common misconception is that dogs cannot see in color. They do, but not complex colors like humans do. Sifferlin says dogs are likely to see yellow and blue tones well, but reds and oranges are more difficult for them to perceive.
Dogs have better night vision than humans, and they are adept at detecting movement even in low light.
Sniff
It is believed that the area of ​​a dog’s brain dedicated to smell is 40 times larger than that of a human. Not only that, but dogs also have hundreds of millions of scent receptors in their noses, compared to just 400 for humans.
According to the author, dogs smell continuously as they breathe, unlike humans, who only smell when inhaling.
Taste
Dogs don’t excel in the taste department, Sifferlin says. While people have around 9,000 taste buds on their tongue, dogs only have around 2,000.
But a limited range of tastes doesn’t mean dogs aren’t open to enjoying new things. As anyone who has lived with a dog knows, if something is edible – or even if it isn’t – they will try it.
Chocolate, garlic, coffee, and onions are believed to be harmful for dogs’ digestion.
Ring
Dogs have very fine hearing and can detect sounds of significantly higher frequencies than humans can hear.
They are also better than humans at isolating sound, which means that in a very noisy area, they are adept at finding their target, Sifferlin explains. Hearing is considered the second best sense in a dog, after smell.
Robert Crais said: “The sense of smell in all dogs is their main gateway to the world around them. ”
