Originating from Germany for herding, Belgian Malinois are valued for their great work ethic and endurance in the past. Today these dogs are more than companions, offering loyalty and protection to their family members. However, as working dogs, they need plenty of care and are well suited to experienced owners.

Owing to their territorial instincts, Belgian Malinois make great guard dogs for high crime areas. Their protective instincts, energetic personalities, and highly trainable nature make them great police and military dogs, as noted by Britannica. They need early socialization and consistent training to excel as protection dogs in family life.

Belgian Malinois possess a strong prey drive, which is why they are prone to chasing after small furry friends. To curb this behavior, make sure they have fenced yards, are leash trained, and are physically and mentally satisfied enough to remain calm and happy.

Cane Corsi are intelligent and powerful in build, and with an exceptional protective nature, they make excellent guard dogs. They were originally bred in Italy to guard wildlife, hunt wild boar, and also used by the army of the Roman Empire. They demand ample exercise and mental stimulation daily to burn off their energy levels.
