Territorial Aggression in Dogs
Territorial aggression may be a prized attribute for owners looking for a good
guard dog, but it can ultimately have a lot of downsides. While it is an
innate quality in certain dog breeds such as German Shepherds, Akitas, or
Rottweilers, a territorial and aggressive dog can turn out to be a big
liability. Hence, the series of lawsuits, specific dog breed legislations, and
so forth that come along with owning a territorial dog.
Dogs Are Territorial by Nature
Protecting territory is in a natural canine instinct. In the wild, canines
tend to claim territory and will defend it through intimidating barks if other
dogs or animals get too close. This is an instinctive way to protect mates,
young puppies and dens where the dogs sleep.
Today, this instinctive nature has remained partially unchanged in the dog,
therefore it is used to the owner’s advantage to protect personal property.
The typical cliché of a mailman or gas-meter guy being barked at or chased is
a classic example.
Often, a fear component is at the base of what seems like territorial
behavior. However, the territorial response can be greatly diminished with
proper socialization and some changes.
While it is true that some dog breeds were genetically selected to be good
guard dogs or watch dogs (think the many small dogs who bark at the minimal
sound), in many cases, dogs can be taught to be less territorial.
Of course, this is best if it is accomplished from a young age, since once
mature, most dogs tend to develop territorial tendencies such as urine
marking, barking at strangers and generally becoming more aloof towards people
approaching their property.
How to Reduce Territorial Aggression in Dogs
Following are some helpful tips on how to stop territorial aggression in dogs.
If you own an aggressive territorial dog, do not try to curb their tendencies
on your own, rather, seek the assistance of a dog behavior professional.
As previously mentioned, there are dog breeds that make better guard dogs or
watch dogs than others. This is because they have been selected for their
guarding or watch dog qualities.
While some guard dogs may be taught to be less territorial, the guarding
instinct may still remain up to a certain extent unless you work heavily on
training and socializing. For example, Rottweilers are considered territorial
dogs, but in the right hands and training, they can turn into the dogs of your
If you do not want a dog that may potentially protect your property, it is
best to skip the guarding/watch dog breeds and look for other breeds that are
less apt to this job. For example, Siberian huskies have a reputation for
making lousy guard dogs.
Socialize Your Dog
Remember to socialize your dog. Enroll them in classes, and teach your dog
that people are not a threat that needs to be sent away. Have your mailman
deliver treats every time he passes by. Have friends and neighbors stop by and
give treats. Let your dog learn that people coming to the property means great
However, consider that what may look like territoriality is instead something
else. A dog that is happy to see people may develop what’s known as barrier
frustration, which often resembles a lot territoriality in its manifestation
(barking, growling, lunging). Instead, this behavior surfaces when a dog is
eager to meet and greet, but frustrated because a fence, gate, window or other
barrier prevents him to. Once free of any barrier, these go on to meet and
greet people happily.
Prevent Rehearsal of Territorial Behavior
The more a dog engages in a behavior, the more the behavior is reinforced.
Therefore, you’ll have to take steps to prevent rehearsal of the problematic
behavior. These tips will be help teach your dog that guarding the home is no
longer their responsibility:

- Prevent your dog from charging at the window, fence or door.
- Limit access to areas where your dog tends to engage in territorial behaviors and where you cannot provide guidance. You can do this by allowing your dog to spend time in a room that is farthest from the window or confine him to an area away from the window blocked off by a baby-gate. As the saying goes, “out of sight, out of mind!”
- Block visuals. You can do so by applying some opaque window film to your windows so to prevent your dog from seeing outside.
Make It Clear That You Are the Decision-Maker
Make it clear to your dog that you will be the one that will decide if that
stranger coming into your house will be your friend or foe. Your dog should
look up to you for advice on how to behave in the presence of that stranger
that entered your property and not take the decision in his hands, or better,
Stay in front of the window or door when you recognize a trigger, and feed
your dog treats before he has a chance to react. You can find more on this
exercise among these dog impulse control games.
“You need to provide your dog some rules. The dog is acting out of the
mistaken belief that it’s up to him to control who comes into the house and
who doesn’t. So the rule might be that when someone comes to the door,
that’s the cue for the dog “to sit, or go in another room, or whatever you
— Dr. Borns-Weil, veterinary behaviorist
Rottweilers are good guard dogs that use a ”watch and see” approach. They
tend to examine circumstances before acting. In the picture are my Rottweilers

Claim the Door
If your dog flies up to the door when a guest is knocking, tell him to stay
aside. This will help your dog understand that you are the one that takes care
of your guests. You should be able to open the door undisturbed, and your dog
should leave you ample space to open the door.
A good method is to teach the dog the stay command or tell your dog to “go to
your mat” even when the door is knocked or a bell is rung. Practice this with
Thank Your Dog, and Say “That’s Enough!”
Some dogs can be quite good barkers when somebody is near or in their
territory. If you do not want a territorial dog, you do not need to punish or
yell at your dog for barking. Rather, simply thank your dog for the bark,
inspect your place for any intruders, and tell your dog ”that’s enough”
after you acknowledge all is safe. Pop a treat for complying. A dog that gives
a warning bark or two is a good thing, and should be acknowledged. You never
know what could happen.
Watch Your Feelings
You may hide your feelings of fear towards a suspicious person, but it’s
likely that that message was relayed all the way down the leash. The truth is
that dogs are very in tune with their owners, and they can easily perceive
feelings of anger, fear or anguish.
When dogs feel you are uncomfortable, they may take what looks like a
protective role—but most likely it’s fear, causing them to growl and act
defensively towards that person. So, remember to keep your cool or keep your
dog away from situations that do not make you comfortable.
Keep Your Dog Contained
A dog that is left in an un-fenced area tends to believe that they own quite a
large area and may become territorial even out of the property limits. On top
of this, there are many risks with having off-leash dogs. It is best to fence
off your property so your dog has some sort of boundary to remind him that
this is his place and so he’ll stay out of trouble. Better yet, prevent your
dog from rehearsing the territorial behavior by keeping him inside and outside
only when he’s with you.
Invite Strangers Over
Try to invite people that your dog has not met onto your property and show
your dog that they are friendly. A good way to start is by having friends pass
by your property and toss a few treats when the dog is not barking at them.
Then, invite them over and let them toss treats every time the dog does not
act territorial. Use the treat and retreat game. Here is an example of
behavior modification done on a dog barking when somebody enters the room.
There are people who own dogs that literally love the mailman because they
have told the mailman to ”deliver” the dog some goodies every time he brings
the mail. For more on this read, Why Dogs Hate the Mailman.
As seen, there are various ways to prevent or at least reduce some territorial
aggression in dogs. While a dog that fiercely bares its teeth and growls at
strangers may be a liability, a dog that emits one or two warning barks may be
a good thing and should be acknowledged with a ”thank you”.

If he ”always wants to do his will” he sounds like he needs some obedience
training first. Have him take a class, and then once he is better manageable,
you can try the above tips. He needs to be able to listen to your commands and
be under control or you may have a huge liability on your hands. I would
suggest having a trainer show you how to fit a ”gentle leader” and then work
on commands and finally work on some counter conditioning where guests bring
good things as treats and should no longer be perceived as threats. Here is a

I have a Komondor, and i’m having problems. I can’t invite anyone over because
he is very territorial. He doesn’t bite, but he jumps and intimidates, and I’m
afraid he could have other reactions. The problem is that the tips given here
are difficult to apply because he is huge, and he always want’s to do his
will. Any idea how to control this problem?
