The dogs are very intelligent, defining intelligence as the good capacity of developing in the environment, because their environment is us. They can understand us very well because they are been molded for that. The dogs come from the wolf. It is thought that the wolves approached to men for the leftover foods of the men, becoming more docile. Since that moment, the man has domesticated them, lose them some abilities to hunt and detaching others, making many shapes of them.
One of these enhanced features is the smell. The dog can smell 40000 times better than humans, detecting many different odors even over long distances. The bloodhound is the best breed to smell.
The dogs have an impressive ability of association. Experiments have shown that dogs can detect signals from us, like our hands, our eyes and our voice, among others, doing it much better the chimps. What demonstrate the great link between dogs and men.
This good development is used to make Helper dogs, which are trained for people with disabilities. This training is done early, when they are puppies, showing them all the things of our world to which they will face in future. When they are ready, they are graduated and delivered to their new owners, becoming real lifesavers.
The dogs can associate objects with words. One dog called “Rico” has shown an amazing ability in this area. This border collie has been tested by rigorous experiments and found to understand the meanings of about 200 different words. He also can discriminate unknown objects by exclusion. This is called "fast mapping", which is developed by children since two years old.
This leaves the question whether ability is doable for all dogs or it is just an exception. Experiments with others dogs have shown that Roco wouldn`t be the one
Are really dogs geniuses? May be they are misunderstood geniuses. One doberman called Donnie has shown to make interesting patterns with her toys. May be she does that to express something, who knows,,,
The knowledge about their whole intelligence is still incomplete. What is known is they understand us better than they understand themselves
