why dogs are very sensitive to smell
Hello aspirant,
A dog's sense of smell helps them find a mate, offspring, food, and avoid any type of predators. Dogs can smell up to 100,000 times better than a human. They also possess up to 300 million olfactory receptors in their noses, compared to about six million in us. And the part of a dog's brain is devoted to analyzing smells which is 40 times greater than ours.
Thank you.
