Doggy curiosities that will surprise you


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.

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).
