Are Belgian Malinois aggressive?

No, Belgian Malinois are not normally aggressive despite having strong protective instincts and being wary of strangers. However, they can display aggressive behavior if they are not properly trained, socialized, or provided adequate mental and physical stimulation. Any unexpected aggression can result from various factors such as genetics, environment, and training. Pain, discomfort, or underlying medical conditions can sometimes contribute to changes in a dog’s behavior, so it may also be worth visiting a vet to rule out their health as a cause for signs of aggressive behavior.
