Does all belgian malinois dogs are intelligent or possessed the same traits?

Nope, there is not and I told you that the other day on another question you posted. It depends on where the dog came from, what bloodlines, what type of exposure the dog had as a puppy and what kind of training you are looking to do with one. There are some stupid malinois out there, I know, I have seen them. There are also some shy/sharp dogs too. Then you have the real working type of malinois that most people cannot handle because of their temperament. Which one is yours like? You seem to be looking for answers and hoping for something more then what you have, but, it is impossible for anyone here to tell you more about your dog without actually seeing it. What are you , specifically looking from this dog? Can you find out where he came from? What are his bloodlines?
