1. Obedience: A well-trained guard dog should be obedient and respond to commands without hesitation. The dog should be able to sit, stay, come, and heel on command, and should also be able to respond to commands specific to guard duties, such as “watch” or “alert”.
2. Socialization: A well-trained guard dog should be socialized and comfortable around people and other animals. The dog should not be overly aggressive or anxious, and should be able to differentiate between a real threat and a non-threatening situation.

4. Alertness: A well-trained guard dog should be alert and aware of its surroundings at all times. The dog should be able to detect potential threats and alert its owner or handler without being overly aggressive or reactive.
5. Discernment: A well-trained guard dog should be able to differentiate between real threats and non-threatening situations. The dog should not be overly aggressive or reactive to non-threatening stimuli, such as a friendly visitor or a harmless animal.
6. Physical ability: A well-trained guard dog should be physically fit and able to perform its duties effectively. The dog should have good endurance, strength, and agility, and should be able to apprehend a suspect if necessary.
7. Handler relationship: A well-trained guard dog should have a strong bond with its handler. The dog should be responsive to its handler’s commands and should be willing to work together as a team.
