Do dogs understand what we say? People speak different languages but do dogs understand what people say? They are our life companions and seem to understand even more at times than we say. They understand what our face expressions mean. Dogs adapted to people in all spheres of life. They even have different face expressions mimicking behavior of humans. They understand so many worlds and can even be polyglots. Watch how this dog can speak English, French and other languages. Doggy does not seem to speak Italian, but it is not surprising. So many languages! A real polyglot!
