German Shepherds are known for being intelligent, loyal, and protective dogs. With proper training and socialization, they can make excellent guard dogs. Here’s a step-by-step guide on how to train your German Shepherd to be a guard dog.

Key Takeaways

  1. Start socialization and obedience training early using positive reinforcement. This establishes you as the leader.
  2. Teach important commands like “sit”, “stay”, “quiet”, “leave it”, and “watch him” to control their behavior.
  3. Encourage alert barking at unusual sights and sounds, but teach them to stop barking on your command.
  4. Set boundaries by walking perimeter regularly and discouraging fence charging.
  5. Avoid encouraging aggression – use rewards-based training only. Seek professional help if needed.
  6. Use proper equipment like harnesses and leashes, not punishments like prong collars.
  7. Be a strong, consistent pack leader. Set rules and reinforce them. This builds your bond and handling skills.

Step 1: Start Training and Socialization Early

The first step is to begin training and socializing your German Shepherd at a young age. Experts recommend starting basic obedience training from 8 weeks old using positive reinforcement like treats and praise. Attend puppy classes to get them accustomed to listening to you around distractions.

Expose your German Shepherd puppy to a wide variety of sights, sounds, people, animals and environments in a controlled, positive way from 7-8 weeks old. Let them meet strangers and investigate new things under your supervision, rewarding calm behavior. This prevents fearfulness later on.

Step 2: Focus on Obedience Commands

Once your German Shepherd understands the basic cues like “sit”, “stay”, “down” and “come”, you can start training more specialized obedience commands important for their guard dog duties.

Teach “leave it” to control their reactions to things like other dogs when on walks. The “watch him” command instructs them to look at a stranger until you give another command, important for controlled monitoring.

The “speak” or “bark” cue tells them when to alert you to something suspicious. Equally important is “quiet” or “enough” to stop barking on your command, so they don’t become a nuisance barker.

Use rewards-based training methods so your German Shepherd enjoys learning from you. Keep training sessions short and fun when they are puppies to develop focus.

Step 3: Encourage Alert Behavior

Once your German Shepherd understands cues like “bark” and “quiet”, you can encourage their natural vigilance and barking at unusual sights and sounds, which is key for guard dog duties.

When they notice something out of the ordinary and bark, praise them verbally, then go and check what they are barking at. Give treats when you return for warning you about a potential threat.

You can practice having friends approach your home for your dog to alert on while supervised on a leash. When they bark, give the “quiet” command followed by praise and a treat when they stop barking.

This teaches them when it’s appropriate to sound the alarm to threats vs becoming a nuisance barker at every sight and sound. Stay calm when training so your dog knows there is no real danger.

Step 4: Set Territorial Boundaries

As your German Shepherd matures, walk them frequently around the perimeter of your property to establish their territorial boundaries. Give a strong “leave it” or leash correction if they try to charge the fence at passersby.

When at home, discourage reactive barking at routine sights like the mail delivery through windows. But reward unusual bark alerts directed at true threats like strange people entering your yard at odd hours. This helps them learn proper alert behavior.

Step 5: Handle Reactivity Issues

If your German Shepherd shows unwarranted aggression like growling, lunging or biting, seek help from a professional trainer to address the root causes through positive training. Do not try to punish or suppress the behaviors, as this often makes them worse.

Until any reactivity issues are resolved, manage your dog by keeping them confined, leashed or muzzled in public for safety. Make sure children do not interact with them unsupervised. Teach the “leave it” command and correct unwanted behaviors.

Step 6: Be a Strong Leader

Guard dog training requires you to be a confident, consistent pack leader to your German Shepherd. Set clear household rules and routines and stick to them. Reward good behavior and correct unwanted behavior.

Use firm, assertive body language and tones when giving commands. Take your dog to regular obedience training sessions to strengthen your bond as their leader who gives guidance. They will look to you for direction when responding to potential threats.

Step 7: Avoid Aggression Triggers

While German Shepherds should alert you to real threats, encouraging aggressive tendencies can be dangerous. Never engage in rough play or training that promotes aggression. Avoid dog parks where they can learn and rehearse reactive behavior.

Show calm confidence when encountering triggers like strangers on walks. Create positive associations with encounters by rewarding non-reactive behavior. Seek professional advice immediately if aggression issues arise.

Know When to Get Help

If your German Shepherd is displaying unwarranted aggression or fearfulness, seek help from a professional dog trainer or behaviorist. They can assess if there are underlying issues contributing to these behaviors. With their guidance, create a customized training plan to address the problems through positive methods.

Signs you may need to get help include growling at or chasing strangers without cause, nipping or biting, separation anxiety, fear of other dogs or new environments. These behaviors need addressing before you can do further guard dog training.

Training a German Shepherd to be a guard dog takes time and consistency. But by understanding their needs, bringing out their natural protective abilities and avoiding aggression, you can develop a devoted companion who helps keep your property safe. With the right approach, they’ll take pride in their important job.


Here are answers to some frequently asked questions about training a German Shepherd to be a guard dog:

How old should a German Shepherd be before starting guard dog training?

German Shepherds can start basic obedience training from 8 weeks old. More formal guard dog training should wait until at least 18-24 months when they reach full mental and physical maturity.

Should I send my German Shepherd away for special guard dog training?

This is usually not necessary. You can do the training yourself through early socialization, establishing yourself as pack leader and rewarding desired guarding behaviors at home. Only use offsite protection training as a last resort if problems arise an expert needs to address.

What commands should I teach a guard dog?

Start with basic obedience like sit, stay, down, come and heel. Important commands for guard dog duties include “bark” or “speak” to alert you and “quiet” or “enough” to cease barking. “Leave it” and “watch him” are also useful for controlled reactions to sights like strangers.

How do I prevent excessive barking?

Excessive barking stems from lack of training and leadership. Teach your German Shepherd the “quiet” command and reward them for stopping barking on cue. Discourage demand barking for food or attention. Meet their exercise needs. And set a predictable routine so they are less on high alert.

Should I play aggressive games with my German Shepherd?

No, avoid any game or training that encourages aggression like tug of war. This can reinforce biting and aggressive tendencies, which is dangerous. Instead play fetch, hide and seek and obedience games that provide an outlet without promoting reactivity.


Training a German Shepherd to be a guard dog requires time, consistency and patience. Start socialization and training early using positive reinforcement to establish yourself as the leader. Teach commands like “bark”, “quiet”, “leave it” and “watch him” to control their behavior. Set clear boundaries but avoid encouraging aggression. Instead, focus on rewarding desired behaviors.

Be a strong, calm leader and seek professional help with any aggression issues. With the proper techniques and commitment, you can develop your loyal German Shepherd’s natural protective instincts into an effective guard dog that helps keep your family and property safe.

The bond built through positive training strengthens your relationship as your German Shepherd matures into their guarding role.
