Managing Your Dog’s Aggression Towards Other Dogs

If you’re reading this, chances are you’re dealing with a fur-baby who’s a tad too feisty around other dogs. You’re not alone – this issue is common, but don’t fret. There’s a lot we can do to help our dogs stay calm and collected during their doggy social hours. In this article, we’ll dig deep into understanding why this behavior occurs, how to spot it, and what you can do about it.

Understanding the Behavior of Aggression Towards Other Dogs

Aggression towards other dogs is a fairly common behavioral issue. It can be distressing for owners and dangerous for the dogs involved, as well as other dogs and people around them. Understanding the triggers and reasons for this aggression is the first step to addressing it effectively.
Dog-on-dog aggression is something that many pet owners dread. But it’s crucial to understand that aggression is often a form of communication for dogs. They might be trying to say, “I’m scared,” “I’m uncomfortable,” or “I need space.” While it’s not a pleasant way for them to communicate, it’s one that comes naturally to them.
Aggression can appear in several forms – growling, barking, snapping, or even biting. Sometimes it’s directed at other dogs in the same household, but often, it’s aimed at dogs outside of the home, like on walks or in the park. It’s also important to know that any breed can exhibit aggression. It’s not about the type of dog but rather about their experiences, training, socialization, and sometimes, their health.
A key thing to remember is that dog-on-dog aggression is a common issue and something that can often be improved with time, understanding, and consistent training. Your dog isn’t ‘bad’ because they’re showing aggression. They’re just struggling with a problem that they need your help to overcome.
  • Fear or Anxiety

    Fear or anxiety can trigger aggression. A dog who has had negative experiences with other dogs in the past might react aggressively out of fear when they encounter other dogs.

  • Dominance or Territoriality

    Some dogs display aggression to assert their dominance or protect their territory. This can occur when a new dog is introduced into the home, or when they meet unfamiliar dogs in places they consider their territory.

  • Resource Guarding

    Dogs might display aggression when they feel that another dog is about to take away a valued resource, such as food, toys, or access to their owner’s attention.

  • Frustration (Barrier Frustration or Leash Aggression)

    Some dogs react aggressively when they’re unable to approach other dogs due to barriers like fences or leashes. They can become frustrated, which can lead to aggression.

  • Health Issues

    Certain health issues can increase a dog’s aggression. Dogs suffering from conditions causing pain or discomfort may become irritable and react aggressively.

  • Lack of Socialization

    Dogs that haven’t been adequately socialized may feel uncomfortable around other dogs and respond with aggression. Proper socialization involves exposing puppies to a wide variety of experiences, including interactions with different types of dogs.

Addressing aggression involves understanding the specific triggers for each dog, and then working with a professional dog trainer or behaviorist to implement a behavior modification plan. In some cases, consultation with a veterinarian may also be necessary to rule out potential medical causes for the aggression.

Signs of Dog-on-Dog Aggression

Identifying the signs of dog-on-dog aggression is the first step toward addressing the issue. Here’s what to look out for:

First and foremost, let’s chat about why our dogs might turn into Mr. Hyde when they spot another canine in their line of sight. It’s crucial to remember that dogs aren’t born aggressive; they become that way due to various factors.

  • Communication Gone Wrong:

    Dogs have their way of communicating with each other. What might seem like aggression to us could be them trying to assert dominance or establish a social hierarchy. It’s their version of saying, “Hey, I’m the boss around here!”

  • Fear or Insecurity:

    Sometimes, aggression is a dog’s way of saying, “I’m scared.” If a dog feels threatened or fearful, they might resort to aggressive behaviour to protect themselves.

  • Lack of Socialization:

    Dogs that haven’t been properly socialized during their early months may not know how to behave around other dogs. It’s like being thrown into a social gathering without knowing any of the unspoken social rules. Yikes!

  • Past Trauma:

    Dogs that have had negative experiences with other dogs in the past might associate all dogs with that bad memory. It’s their way of saying, “Once bitten, twice shy.”

  • Unfriendly Body Language:

    If your dog stiffens, raises their tail high, pins their ears back, or shows the whites of their eyes (often called ‘whale eye’), they’re probably feeling aggressive or fearful. These are all signs of a dog who is uncomfortable and may react aggressively.

  • Growling or Snarling:

    These are clear signs of aggression and a warning to the other dog to back off. Even if they’ve not acted on it yet, your dog is showing that they’re feeling aggressive.

  • Changes in Appetite:

    Dogs dealing with separation anxiety might stop eating or drinking when left alone, indicating that their distress significantly impacts normal behaviors, including their appetite.

  • Lunging or Snapping:

    If your dog is trying to get at another dog, even if they’re on a leash and can’t reach them, it’s a sign that they’re feeling aggressive.

  • Bites:

    In extreme cases, your dog might bite another dog. It’s important to note that bites can vary from minor nips that don’t break the skin, to more serious bites that require veterinary attention.

The sooner you can identify these signs, the quicker you can intervene and start helping your dog to feel more comfortable around other dogs. Remember, prevention is always better than cure, so the earlier you can address this issue, the better.

Triggers of Aggression Towards Other Dogs

Now, let’s get into the nitty-gritty of what exactly triggers our canine companions to display aggression towards other dogs.
  • Seeing Other Dogs:

    This one might seem like a no-brainer, but some dogs might only show aggression when they see another dog, particularly if that dog is of the same sex.

  • Invasion of Personal Space:

    Dogs, like people, value their personal space. If another dog gets too close too quickly, your dog might react aggressively.

  • Resource Guarding:

    Is your dog a bit possessive about their toys, food, or even you? This could lead to aggression if they feel another dog is threatening to take what’s ‘theirs’.

  • Leash Reactivity:

    Some dogs feel restrained or stressed when on a leash, which could make them more likely to react aggressively when they encounter other dogs.

Understanding these triggers can help us to avoid potentially stressful situations for our dogs and start thinking about how to work on these issues. Remember, your dog isn’t being ‘bad’ – they’re just responding to the world in the best way they know how! Next, let’s explore how we can address these triggers and help our dogs to feel more relaxed around other pups.

How to Handle Aggression Towards Other Dogs – Do’s and Don’ts

Handling dog aggression isn’t easy, but it is possible. Here are some do’s and don’ts that can help you navigate this journey.


  • Provide Proper Socialization:

    Just like us, dogs need to learn how to interact with others. Start this process early, if you can, by exposing your dog to other dogs in controlled, positive situations.

  • Positive Reinforcement Training:

    Reward your dog for good behavior. For example, if your dog remains calm around another dog, treat them or shower them with praise.

  • Hire a Professional Dog Trainer:

    If your dog’s aggression is severe, it may be best to hire a professional. They can provide insights and techniques tailored to your dog’s specific needs.


  • Don’t Punish After the Fact:

    Dogs live in the moment. If you scold them after they’ve acted aggressively, they likely won’t connect the punishment to the behavior.

  • Don’t Force Interactions:

    Forcing your dog into uncomfortable situations can worsen their aggression. Instead, gradually introduce them to new dogs in controlled settings.

  • Don’t Ignore the Problem:

    Dog aggression isn’t something that will just go away on its own. Ignoring it can potentially lead to dangerous situations.

Remember, managing dog aggression is a marathon, not a sprint. Patience, understanding, and consistency are key to achieving the best outcomes. Let’s move on to some products that might help manage this issue.
