Humans and dogs have been living side-by-side for about 15,000 years and the world dog population has known a pretty significant growth with the United States at the top of the ranking for almost 70 millions dogs and Brazil in the second place with a dog population of 35 millions (UK in the ninth place) according to stevedalepetworld website.
With all this in mind, one might think we know each other very well. but there’s more to dogs than fetching staffs and playing around. Here are some little-known facts about man’s best and oldest friend:
15- Dogs can hear about 4 times stronger than humans.
Basically, puppies can’t hear until the age of 21 days nor they can see too in this period, but by the time their sense of hearing is completely developed, they can hear 4 times stronger than what humans do.
Dogs (dogs with perked ears and not hanging ears) have about 18 muscles in their ears allowing them to be mobile and move in the direction of the sound, whereas humans only have 6 muscles (more information at dogbreedinfo).
14- A dog’s nose print is as unique in identifying them as our fingerprint is to us.
Just as humans are identified by their fingerprints, dogs can be identified by their nose prints. A dog nose print is unique to him and no two dogs have the same print just as no two human fingerprints are the same.
Few places in the United States have already adopted dog nose printing as a common way of identifying lost dogs, however the Canadian Kennel Club has been accepting dog nose prints as proof of identity since 1938. The general consensus is that nose printing is a more reliable way of matching identity, as dog tags can easily be lost or even removed (see more at allpetnews.com).
13- Dogs’ sense of smell is at least 1000 times stronger than ours.
while a dog’s brain is only one-tenth the size of a human brain, the part that controls smell is 40 times larger than in humans. A human has about 5 million scent glands, compared to a dog, who has anywhere from 125 million to 300 million (depending on the breed). With all this, no surprise a dog’s sense of smell is about 1,000 to 10,000,000 times more sensitive than a human’s (depending on the breed) … Continue Reading
