[Fred Hayek]

The Malinois is more intelligent than the GSD. Very good at instinctively assessing a threat versus non threat. The Israelis use them.

The Malinois is more intelligent than the GSD

That is not accurate. The Malinois is more aggressive and focused when training, thus it has become a military favorite. The GSD is the 3rd most intelligent dog there is, behind the Border Collie and Standard Poodle.
