The reason why a Malinois likes to bite children may be due to curiosity, teething period, boredom or play. Because children are smaller and look about the same height as a Malinois, a Malinois will want to interact with and play with children. To avoid this situation, it is best to put a leash on the horse dog and avoid going to places with many people and children. If the horse dog wants to bite a child, the owner needs to stop it immediately to avoid hurting people.
