The Malinois, AKA Maligator, Fur Missile, .... highly intelligent, and may be ball-driven to the point of exhaustion, and go again the next day.

The toyota hilux of dogs. The bastard will just not stop trying to sell beans. I need a dart gun. Even under a running sawmill - no fear in the face of a ball game.

All guts and nuts.

Belgian mailnois, may be ball-driven...
