The Groenendael is (very) intelligent, active, loyal and quietly affectionate. Groenendaels are not a breed for the faint of heart. However for those who have plenty of time, energy, confidence and love, they are wonderful friends. They are dominant dogs by nature, and it is important that they never question their owner’s authority in order to be trainable. It is a large, powerful breed so training and socializing is essential and the only way one can live with the breed. Once you have established your dominance they are incredibly loyal and obedient. They are wary of strangers and protective. They love children as long as they are introduced to them at an early age. The Groenendael bonds deeply to its people and cannot live outdoors or in a kennel. It needs to spend time with its family every day and may experience separation anxiety if left alone for long periods of time.
