Dealing with Dog Aggression: From Understanding to Action

Various factors contribute to a canine’s aggressive behavior, each differing considerably across individual dogs. Recognizing the circumstances that trigger your dog’s aggression is crucial for effective training.

Indicators of a Aggressive dog

By being observant, you may detect early signs of your dog exhibiting aggressive tendencies before they escalate into serious behaviors. These behaviors often follow a rising progression, as indicated below.

  • Getting all stiff and still
  • Hiding the tail between the legs
  • Pulling the ears back
  • Keeping the mouth closed tight or lips pulled back over teeth
  • Showing off teeth
  • Staring hard at something or someone
  • Walking back and forth quickly
  • Making growling, barking or snarling noises
  • Moving towards a person or another animal
  • Giving a ‘nose nudge’ (bumping a person or other animal with the nose)
  • Nipping gently
  • Biting hard enough to tear skin or cause bruising, leaving puncture wounds, or biting repeatedly and quickly


An owner who overlooks the emerging signs of aggression may soon be dealing with a dog that is entirely unmanageable. This situation is an owner’s responsibility, and it does not imply that the dog is inherently “bad.” It merely signifies that it’s time to employ some training strategies for aggressive dogs to help soften your dog’s behavior.


Anxiety-induced aggression in dogs may arise when they feel trapped, unable to escape a situation they perceive as threatening. Dogs with a history of abuse or improper socialization are more prone to exhibit aggression rooted in fear.


Guarding behavior or protectiveness is a prevalent cause of aggression among dogs. Many dogs feel an inherent need to safeguard their belongings, such as food, toys, or personal spaces, even in the absence of any real threat. It is common to see dogs with such behaviors growl when someone approaches their prized possessions or spaces. An especially prevalent form of this protectiveness is food guarding.

Spatial Defensiveness

Inherent in some dogs is an instinctual urge to defend their domain, which may extend to your house or yard, from perceived intruders. This type of aggression can be directed at strangers for some dogs, while others might also act defensively towards familiar people. It’s noteworthy that dogs usually develop territorial behavior as they mature into adulthood.

Defensive Aggression

Being natural social creatures, dogs inherently feel the need to shield their social group members. They can display aggressive tendencies if they perceive a potential threat to their human family, friends, or other pets.


Aggression In some instances, dogs may demonstrate aggressive behaviors as a means of asserting dominance. This type of aggression, often referred to as status-driven aggression, is primarily observed in their interactions with other dogs. With their natural tendency towards forming hierarchical social structures, a dog that perceives itself as the leader may show aggression to affirm its authority.

Aggression in dogs can pop up for all sorts of reasons, and quite a few are linked to the environment they’re in. Say you got your dog from a shelter, there’s a chance they might have had a rough past, and certain things could set them off. That’s why showing them lots of love and making sure they feel safe is super important.

If your pooch is acting all hostile after getting hurt, it’s pretty likely they’re just in pain. When the pain is gone, the aggression should be too. Be aware though—if you’re trying to help them out, you might accidentally cause more pain and get a snap for your troubles. If that happens, better get on the phone with your vet ASAP for advice on how to get your fur friend checked out without causing more discomfort.

Some dogs get really possessive about their stuff or their favorite humans, and might get aggressive when someone else gets too close. In this case, your four-legged buddy needs to learn some manners and realize there’s no need for guarding. This one can be a bit tricky, as it’s often just in their nature, but upbringing can play a part too. For instance, if your dog’s used to hogging all the toys at home, bringing in a new pup might ruffle their fur. If that’s the case, take it slow and easy introducing the new changes, so they get a chance to get used to the idea gradually instead of all at once.

Once you figure out what’s causing your dog to act aggressively, you’ll be in a better place to tweak their training. You might even be able to change up their environment to help them chill out.

How to Train an Aggressive Dog

Record instances of your dog’s aggression and the context in which it occurs. This information is crucial in guiding your subsequent actions. Addressing the root cause of the aggression is key, as the aggressive behavior is merely a manifestation of a deeper issue. There are several strategies available to manage your dog’s aggression and maintain their composure. This process will require patience, consistency, and potentially, the intervention of a professional.

Go to Your Veterinarian

Dogs that typically don’t display aggressive tendencies but suddenly start acting out could be dealing with a hidden health issue. Certain medical conditions like hypothyroidism, physical injuries causing pain, and neurological disorders such as encephalitis, epilepsy, or brain tumors may trigger aggressive behavior.

It’s advisable to consult with your vet if you suspect such an issue with your dog. Appropriate treatment or medication could significantly improve your dog’s behavioral patterns.

Go to a Professional

If a medical issue has been eliminated by your vet, the next step is to seek help from a professional dog trainer or animal behaviorist. Given the severity of aggression issues, it’s not advisable to tackle them alone. A professional can assist in determining the root cause of your dog’s aggressive behavior and devise a strategy to manage it.

Avoid Punishment

Disciplining your dog for aggressive actions often proves counterproductive and can even intensify the aggression. If you react to a growling dog by striking, shouting, or employing another punitive measure, the dog might perceive this as a threat and retaliate by biting.

This form of punishment could also result in your dog biting someone else unexpectedly. For instance, a dog that growls at children is signaling his discomfort around them. If you reprimand a dog for growling, he might not give a warning the next time he’s uncomfortable but may resort to biting directly.

Things to Consider

If you’re contemplating whether to accommodate and treat your aggressive dog, several considerations must be weighed since you, as the pet owner, bear the ultimate responsibility for your dog’s behavior. These factors encompass the risk level associated with living with your dog and the probability of modifying her behavior:

Size Factor

Regardless of other parameters, larger dogs are perceived as more intimidating and have the capacity to inflict more harm compared to smaller dogs.

The Age Element

It’s generally considered that young dogs with aggression issues are more adaptable and easier to rehabilitate than older ones.

Previous Bite Record

Dogs that have bitten previously pose a recognized risk and constitute an insurance liability.

Intensity of Aggression

Dogs that limit their aggression to teeth baring, growling or snapping are notably safer to live and interact with than dogs that resort to biting. Similarly, dogs causing minor bruises, scratches and puncture wounds are less risky than those inflicting serious injuries.

Aggression Predictability

The highest risk dogs in terms of euthanasia due to aggression are those who give little to no warning prior to biting and display inconsistent, unpredictable aggression.

Aggression Targets

The frequency of your dog’s exposure to the objects of her aggression can influence the ease of managing and resolving her behavior.

Triggering Factors

Are the conditions provoking your dog’s aggressive behavior easy or impossible to evade?

Motivating Your Dog

The final aspect to consider is the ease of motivating your dog during the retraining process.

Are Some Breeds More Aggressive Than Others?

Indeed, certain breeds may appear more prone to biting or displaying aggression if we examine the compiled data. There are several factors contributing to this. It’s likely because most dog breeds were originally developed for specific roles in human societies. Some were highly valued for their guarding and protective behaviors, some for their hunting skills, others for their fighting abilities, and some for their sheer determination and resilience.

Even though many pet dogs of these breeds today are not involved in these original roles, their genetic makeup still carries the traits of their ancestors. This could mean that individuals of a specific breed may have an innate predisposition to certain types of aggression. Despite this, judging a dog based solely on their breed is neither precise nor sensible.

The dog’s unique personality and its history of interactions with humans and other animals serve as better predictors of potential aggressive behavior. While it’s crucial to research breeds to ensure that your chosen breed or mixed breed aligns with your lifestyle, the best safeguard against issues of aggression is choosing the right dog for you on an individual level.
