Dog senses are highly developed compared to us humans. We do not look and experience the world as they do and we should be grateful for that little fact. Can you imagine being able to hear noises that span such a range that we would be able to detect the slightest scratch of a mouse at the far side of the house? A dog can hear sounds at four times the distance compared to our limited perception. If that were the case it is fairly conclusive that rest would be a long forgotten memory. It would be even more disturbing if our sense of smell was as sensitive to that of our furry companians we would definitely not be able to cope with the amount of information that is present in our smelly everyday life. Dogs can discriminate smells nearly 100 million times more than humans can!
