My neice has two Dutch Malinois that are competition dogs, dock diving, obstacle courses and the like. Very athletic, very strong, can easily climb ladders get on the roof of her house, climb the 8 ft fence around the house as well. If she lives them home ,she has lights on and announces her presence when she returns. They are quite protective of their castle. Fast ,athletic climbers and a bit bitey are a robbers nightmare!!!!!!
