We have often heard it said that dog is “man’s best friend”,  but in the case of an aggressive dog, not so much! Most dogs will bark to warn you when a stranger approaches, this is a natural part of their role as a member of your “pack”, and most pet owners appreciate that it is part of their job as your pet and companion. However, some dogs take this protective, warning behavior too far, showing aggressive behavior towards, and even attacking strangers. 

Unless you live in an extremely remote location or are a hermit, your dog is going to come into contact with strangers on a regular basis, on walks, in public, and having people such as servicemen and delivery people approach your home. If your dog attacks strangers, this is going to be a serious problem! Not only is it dangerous for the innocent stranger that you come into contact with, but most municipalities have laws against having aggressive dogs, and a dog that attacks strangers can be apprehended and euthanized if it becomes a problem. Getting control of a dog’s aggressive behavior towards strangers is a critical safety issue for others and for your dog.

TopDefining Tasks

Why do dogs get aggressive towards strangers? Sometimes it is due to territorial or protective tendencies--the dog is attempting to protect his territory, which could include your premises, your home and yard, and you. This can cause them to react aggressively to strangers approaching you while on walks, at home or away from the home. Other dogs are aggressive towards strangers because they are anxious and fearful. These dogs perceive the stranger as a danger to themselves, or you, and are attempting to defend themselves by lashing out and attacking the source of their fear, a stranger. 

You can often determine which type of aggression your dog is manifesting by observing their body language. A fearful dog will adopt a submissive stance, may often tuck their tail, crouch or otherwise try to avoid contact with the stranger,  then suddenly lash out quickly, at an ankle or from behind. A dominant,  territorial dog will adopt a dominant stance, lunging towards visitors, barking, making eye contact. Before corrective training for aggressive dogs begins, owners should rule out medical conditions that may be contributing towards aggression such as endocrine conditions or medical conditions causing pain, which may be contributing to aggressive behavior.

The best way of treating aggression towards strangers is to prevent it by socializing your dog when they are young, exposing your dog to lots of different situations and people in a safe, controlled environment, and teaching your dog that strangers are not a threat to you or him. If an older dog exhibits aggression towards strangers or has attacked someone, immediate training and work to prevent someone being hurt is required. 

You may need to engage a professional trainer if you have limited experience in training dogs, as this behavior is critical to stop for everyone’s safety.  Training to curb aggression involves desensitizing your dog to the presence of strangers and establishing control and leadership of your dog so that you can direct your dog to respond in a  calm accepting manner when a stranger is present.

TopGetting Started

Many trainers working with aggressive dogs use a head halter, which allows the handler to control the direction of the dog’s attention and direction and exert authority and leadership over the dog without causing pain to or injuring the dog. If using a head halter, you will need a short lead, as a dog using a head halter with a long lead can get a neck injury if they run and are suddenly stopped on a long lead. A well-fitting collar that will not slip over the dog’s head may also be used. 

This type of training should take place in a controlled setting; having an unplanned stranger approach during a training session can sidetrack your training. You will need to establish firm control, so ensure you have a plan before starting a training session to keep yourself, your dog, and everyone else safe. If at any time you feel overwhelmed, call upon a professional who can help you train your pooch and guide you in the right direction for practice sessions at home.

The Establish Leadership Method

Most Recommended

Ribbon icon1

Take authority

Conduct training exercises with your dog that establish your leadership over your dog, so that they do not view themselves as the dominant pack leader. This will establish that in a perceived threatening situation, your dog is not the ultimate authority. Teach your dog to heel and follow you reliably on a leash, with either a head halter or another appropriate collar. Do not use a flexi leash, which is not useful for exerting control.

2

Have assistant approach

Once you have established a leader relationship, arrange to have a strange assistant approach you, while walking your dog. Stay calm and exert positive energy. Use a head halter and collar if deemed necessary.

3

Exert control

When your dog reacts aggressively to the presence of the stranger, jerk quickly to the side on the leash or in an upward motion. If your dog is wearing a head collar, this redirects your dog. Tap your dog on the side with your leg. Do not hit your dog, you are redirecting him and reminding him who is making the decisions for “the pack”.

4

Proceed

Have the stranger proceed on by, at a safe distance, while you remind your dog you are the leader and continue on your way without reacting. Have your dog follow your leadership.

5

Practice

Repeat, having the stranger repeatedly walk by at a safe distance while you signal your dog to follow you without reacting. This procedure will need to be repeated many times with different assistants over a period of days and weeks. Do not become agitated or aggressive with your dog. Firmly distract him by redirecting him and commanding him to follow you when approached by a stranger. Eventually, your dog will take his cues from your leadership, calmly walking past strangers and not reacting.

The Desensitizing Method

Use an assistant

In a controlled environment, such as your home, where the dog is less anxious, engage an assistant to help desensitize your dog to the presence of strangers.

2

Prepare dog

Put your dog on a leash, with a head halter or well-fitting collar to help control his movements and prevent the dog from attacking your assistant.

3

Approach

Slowly, have your stranger approach your dog. When the dog shows signs of fear or aggression, have your assistant stop and wait.

4

Reward calm

Wait until the dog relaxes. Do not pet him or reward him for his frightened state, but talk calmly and firmly to him until he relaxes. When he is relaxed, then reward him with affection or treats.

5

Approach closer

Have your assistant approach closer. The assistant should approach from the side and with their body not directly facing the dog, which a dog finds threatening. When the dog again shows signs of aggression or fear, stop and repeat previous step.

6

Repeat and vary

Repeat until the dog tolerates the presence of the stranger without aggression or fear. You will need to conduct this with different assistants, daily or a few times a week, for several weeks. Eventually your dog will learn to tolerate strangers and be calm.

The Alternate Behavior Method

Teach 'down-stay'

Teach your dog to respond to a 'down-stay' command in your home, without strangers present. Give your dog the 'down-stay' command repeatedly. Your dog should lie down and stay for several seconds, then be provided with a treat. Gradually increase the length of time and alter how often a treat is provided versus praise and affection as a reward.

2

Practice

Start giving the 'down-stay' command to interrupt unwanted behavior. Gradually increase the length of time your dog is able to hold this behavior. Work from 30 seconds up to four or five minutes.

3

Practice outside

Teach your dog to obey the command when distractions are present. Start moving the exercise outside, while on a leash. Provide the 'down-stay' command and provide treats while outdoors in response to distractions such as squirrels or other dogs. Reward your dog for adopting the 'down-stay' position in response to your command.

4

Have assistant approach

Engage an assistant to approach you and your dog, while outside. When your dog orients to the stranger, provide the 'down-stay' command, have your assistant wait until the dog adopts the 'down-stay' position and relaxes. Reward your dog.

5

Come closer

Have the assistant approach closer, if your dog breaks position, repeat the command, have assistant wait, wait until the dog obeys and relaxes, and repeat until the dog tolerates the presence of the stranger.

6

Repeat

This exercise will need to be repeated several times weekly and for several weeks with different assistants to establish behavior. You may use a head halter while outside to protect your assistant, maintain control of your dog, and prevent any incidents if an unplanned stranger approaches.

Training Questions and Answers

MooseHusky mixTwo YearsQuestion0 found this helpful0 found this helpful

Moose was a loving playful dog, but when he was about 10 months old, someone we know attacked me in front of him. Since then, he's been very aggressive towards anyone he doesn't know, lunging, barking, and snarling, and even nipped someone he's known and loved since he was an 8 week old puppy. We're at a loss as to how to handle the situation.

I highly recommend hiring a professional trainer to help you in person with this. First, pup needs to be evaluated to determine what type(s) of aggression or reactivity are present. For example a dog who is fearful is trained a bit differently than a dog who has learned to use aggression to get what they want or a dog who is prey driven toward something like moving cars. Often treating aggression or reactivity involves building the dog's general trust and respect for you and those who live with you, through things like having pup work for everything they get in life by asking pup to obey a command like Sit before you give them anything. It involves giving pup a lot more boundaries and rules to follow to build structure and predictability into their routine and help them make better choices. If pup has a low tolerance of something or fear, then pup would also be desensitized and counter conditioned to what they are unsure about using food rewards to reward pup for good responses, very gradually increasing his exposure to whatever he dislikes right now. If pup lacks impulse control, then you would also work on commands that specifically help pup increase their level of control over themselves gradually. There may be other specific things that need to be addressed as well. Look for a trainer who specializes in behavior issues like aggression and fear. If pup is aggressive toward strangers or other dogs too, you will need a trainer who works with a team of trainers and/or has access to other well mannered dogs, like the trainers' dogs so that the training can be practiced around a variety of people and other dogs, to help pup generalize what they are learning to people and dogs in general, and not just the trainer and yourself. Best of luck training, Caitlin Crittenden
