A wagging tail can have completely different meanings
Dogs wag their tail to the right if they are happy and to the left if they are frightened. Wagging a tail low means they are feeling insecure and a rapid wagging of tail with dilated eye pupils and tightening muscles implies aggression.
Their sense of smell is 1000 to 10000 times more powerful than humans.
Percentage of the dog’s brain that is devoted to analysing smells is around 40 times larger than that of a human. An average human has around 5 million scent receptors in the nose as compared to 225 million that a German Shepherd can have. And hence dogs have a superhuman sense of smell resulting into some of the most amazing behaviour.
A dog’s nose is as unique as your fingerprints
No two dog noses are the same. They are so unique that dog kennels keep nose impressions of expensive dogs which are used to identify the dog. Some techies should probably design a biometric identification system for dogs as well!!
Dogs are as smart as a 3 year old baby
A 3 year old human child can exhibit simple human emotions like fear, anger, happiness, sadness etc. Innocent and honest affection is also a powerful emotion due to which we love children. All these emotions are also exhibited by Dogs.
Puppies are born blind and deaf
In fact puppies are born with both their ear canals and eyes completely closed and take almost 2 weeks to develop a sense of hearing and vision. That is the reason that new-born puppies need so much care else they can quickly die.
Dogs possess a sixth sense
It is widely believed that dogs can sense diseases in humans like diabetes or even cancer. It is also been observed widely that a dog can sense their own death and they desert their homes to go die in seclusion. The scientific basis of most of these beliefs is the superhuman smelling power of dogs. Diseases lead to a change in chemical composition of the body which can be ‘smelled’ by the dogs.
Dogs dream like humans
Researches have established that dogs have a sleep pattern and brain activity similar to humans while they are sleeping. They are likely to dream about playing outside or eating. Next time your dog is in deep sleep, carefully look at its body movements to guess the type of dream.
Dogs sneeze when playing around with other dogs to signal that they are not being aggressive.
Normally a sneeze is the result of an irritated nose or dust in the air. But dogs display sneezy behaviour when playing with other dogs in order to convey that it is all harmless. This is their method to stop the playing from escalating to a fight.
Dogs dislike being hugged.
To a dog, hugging is more a sign of dominance rather than emotional warmth. Animal behaviourists say that in a dog’s world standing over someone means an intention to dominate the other dog. So be a little more careful while trying to hug a strange dog.
Dogs are the only animal species known to understand visual cues from the human eyes.
Because of the social nature of humans, we have evolved to convey a variety of emotions and moods through different visual cues like wide eyes look for disbelief. It is said that dogs can understand some of those visual cues, an ability which has developed over a period of thousands of years of the domestication of dog.
