criaturitas de dios

                  biomorphosis: Interesting dog facts that you might not know. Dogs don’t feel guilt. Your pet pooch may get jealous, but researchers found those puppy dog eyes are not a sign of guilt. In fact they are just the way we interpret a dog’s reaction to being scolded. Dog urine can corrode metal. Apparently allowing your dog to wee on a lamp-post could be more dangerous than you think - because the acids in the urine can corrode the metal. Dogs can smell disease.  Research at the Schillerhohe Hospital in Germany found dogs have an incredible ability to recognise the smell of a range of organic compounds that show the human body isn’t working as it should. A wagging tail doesn’t always mean they are happy. Tail wagging has its own language. Apparently dogs wag their tail to the right when they’re happy and to the left when they are frightened. Wagging low means they are insecure and rapid movements accompanied by tense muscles or dilated pupils can signal agression. Dogs have their own fingerprint. A dog’s paw print may look pretty generic but their nose print is actually as unique as a human fingerprint. Their combination of ridges and creases is so distinct it can actually be used to identify them. Dogs can fall in love.  It may sound far fetched but Paul Zak, a professor at Claremont Graduate University in California, found that a dog’s brain releases oxytocin - the love hormone - when it interacts with humans and dogs, just the same as a human brain does when we hug or kiss. When dogs kick after going to the bathroom.  Why do they do that?  they are using the scent glands on their paws to further mark their territory. No night vision goggles needed! Dogs’ eyes contain a special membrane, called the tapetum lucidum, which allows them to see in the dark.
