According to the statement of one of the famous American psychologist Stanley handlers and Coren, a dog in their mental development is similar to the 2-year old child. The dog can do simple arithmetic, count and learn up to 165 different words. Stanley Coren's statement confirms Joseph Topal, head of a group of Hungarian scientists of the Academy of Sciences. The researchers found that the dogs do resemble small children, their way of learning is observational and imitative.

Austrian scientists as a result of various tests identified in the dog a feeling of justice. Two pets during the experiment always gave encouragement for the execution of commands, and so that they may see each other. After another command executed one dog deprived of awards, and as a result, she refused to perform anything else afterwards.
