Well-raised and trained Malinois are usually active, friendly, protective and hard-working. Many have excessively high prey drive. Some may be excessively exuberant or playful, especially when young. They can be destructive or develop neurotic behaviors if not provided enough stimulation and exercise. These are large, strong dogs that require consistent obedience training, and Malinois enjoy being challenged with new tasks. They are known as being very easy to obedience train, due to their high drive for rewards.
