Dog senses

Canines have especially strong dog senses of smell and hearing.

A dog’s sense of smell is so powerful, it’s like saying dogs smell in color while people smell in black and white.

Most dogs have between 200 and 250 million scent receptors. People in comparison have approximately 5 million. Their combined olfactory “system” is 4 times greater than ours.

When compared to humans, a dog’s hearing is superb. They can hear frequencies and volumes people can not hear.
