Re: Do Emotions have an Aroma
Some info on dogs' sensitivities...........
I think this explains their phenomenal ability to scent things.....
"The Nose: A dog interprets the world predominantly by smell, whereas human predominantly by sight. Even though a dog’s brain can be one tenth the size of a human’s brain, the part that controls smell is
40 times larger than in humans.
A human has about 5 million scent glands whereas dogs have 125 million to 300 million (depending on breed), meaning their sense of smell is 1,000 to 10,000,000 times better than humans!
Have you ever wondered why their noses are wet? It’s because the mucus on a dog’s nose actually helps it capture scent particles."
"The Ears: Puppies are born deaf and cannot hear until they are 21 days old. By the time their sense of hearing has developed, they can already hear
4 times the distance of a human with normal hearing.
Dogs can hear higher pitched sounds and can detect a frequency range of 67-45,000 Hz, compared to a human range of 64-23,000 Hz."
Humans can see further than dogs, though, and are also better at seeing things close up than dogs are, plus humans have a wider range of colour-detecting cells in their eyes.
