How well do you know your furry friend?
In this post we discover characteristics, peculiarities and curiosities about the behavior, character and anatomy of dogs.
Dogs are born deaf and blind. During the first two weeks of life, puppies perceive the world only through touch and smell, as their eyes and ears are sealed because they were not fully developed at birth. It is in the third week that their eyes and ears open, giving them a whole new way of sensing life.
They do see in color, but they do not see as wide a range as humans. However, they perceive movement better and are able to focus attention on a specific point at a distance of meters.
As for their sense of smell, their snout is approximately 50 times superior to that of humans.
Dogs are able to detect diseases thanks to their incredible sense of smell. Many dogs save lives with the simple gesture of sniffing a person. In fact, there are so-called “medical alert dogs”: specifically selected and trained to detect through their sense of smell and warn their owner in advance when they are going to have a sugar high or low (diabetes) or a sensory disconnection crisis (epilepsy).
A dog’s nose is equivalent to its fingerprint. Their muzzles are unique and unrepeatable. The police use this to know if a criminal’s dog has been at the scene of a crime to catch him.
Taste is the least developed sense in dogs. It has been proven that they are capable of perceiving sweet, sour and bitter tastes. On the other hand, they do not distinguish salty tastes.
They have 42 teeth, 10 more than us humans. If you want to know more about their teeth and hygiene, check out this post.
Dogs sweat too, but instead of sweating through their skin, they sweat through their paw pads. Check it out next time it’s hot!
As with humans, dogs can suffer from depression. It can be prevented if you give them enough attention and take them for frequent walks.
