Dogs are smart as two year old kids

American Psychologists who deal with animal behavior, prove that dogs are intelligent as two years old children. They can understand 250 words and gestures, they can count to five and to solve simple mathematical tasks. At the University of Vancouver, Professor Stanley Coren led the research and concluded that there is a difference between the races of the dogs. Proved that the most intelligent are: Scottish shepherd (Lesi), German Shepherd and Retriever, while mastiff and pekingese at the bottom.
This research proved that dogs are much more intelligent than what is considered until now, and further research may help that some fully train dogs to help people with diseases or defects, which required neseseri assistance.
