1: Dogs drink water by forming the back of their tongue into a cup. Allowing them to bring larger quantities of water into their mouth.
2: Spiked dog collars were invented in ancient Greece and were originally designed to protect dogs throats from wolf attacks.
3: The wetness of a dog’s nose is essential for determining what direction a smell is coming from.
4: Seeing eye dogs pee and poo on command so that their owners can clean up after them. Male dogs are also trained to do their business without lifting their leg.
5: Dogs don’t enjoy being hugged as much as humans and other primates. Canines interpret putting a limb over another animal as a sign of dominance.
6: Dogs can see in color
It is a common myth that dogs can only see in black and white but they can actually see colors – just not as vividly as humans.
They only have two cones in their eyes to detect colors, whereas humans have three. That means dogs see colors on a blue and yellow scale but cannot distinguish between red and green. On the other hand, they have better night vision than humans.
7: Dogs can smell disease
If your canine friend is acting strange there might be nothing wrong with them – the problem could be with you.
Research has found – dogs have an incredible ability to recognize the smell of a range of organic compounds that show the human body isn’t working as it should.
That means your dog can actually diagnose cancer – as well as diabetes and the early signs of an epileptic seizure.
8: Dogs dream just like you
This won’t come as a huge surprise to anyone who has watched their own dog twitching or whimpering in their sleep. Dogs have the same brain wave patterns while they are asleep as humans, so they dream just like we do.
But what is more surprising is the fact that not all dogs dream the same amount. Small dogs actually have more dreams than big dogs. For example, a small dog such as a toy poodle may dream once every 10 minutes, whereas a great dane may have around an hour between each dream.
9: Dogs have three eyelids, an upper lid, a lower lid and the third lid, called a nictitating membrane, which helps keep the eye moist and protected.
10: Unlike humans who sweat everywhere, dogs only sweat through the pads of their feet.
