There are many types and reasons for dog aggression. The following is a list of “what makes dogs aggressive.”
Prey Drive : the desire to chase movement. Aggressive dogs high in prey drive will bite when stimulated by movement. These are classic Schutzhund dogs.
Territoriality : aggressive behavior due to guarding traits; dogs may guard the home or the yard.
Natural Protection : aggressive behavior exhibited due to the guarding of the dog’s owner. This does not include the house and the yard, only a specific person or people.
defense: aggression due to the dog guarding his or her own body. This type of aggressive behavior is different from dominance. Aggression due to defense is based on fear, whereas dominance is based on the dog’s will.
Dominance : the dog that decides when and what he will do is dominant, and this includes dog-to-dog aggression. In some dog breeds and mixed breeds, this leads to aggression. Even the most dominant dogs can be trained to be less aggressive through effective obedience training. Left untrained, their dominance often leads to an overtly aggressive dog. Interestingly, dominant dogs usually have very stable nervous systems.
Re-directed : A dog that is in one mode of aggression may get distracted by another and re-direct his aggression towards the new object, person, or other animal. Terriers have high prey drives and redirected aggression.
Object Aggression : Aggression due to toy or food guarding.
Sibling : signs of aggression that are exhibited when littermates or dogs of similar age or dominance level fight.
Same Sex : This is when two males or two females fight for dominance of the household.
Inappropriate Aggression : This is any type of aggression that is not provoked and/or warranted.
Tips for Correcting Dog Aggression
Aggression in dogs is a complex issue that can stem from a variety of factors, and it can be alarming for any dog owner. Whether it’s growling, snapping, or attacking, aggressive behavior in dogs can cause concern for both the dog and the people around them. It’s important to understand the root causes of aggression in dogs so that you can manage it effectively, ensure the safety of everyone involved, and help your dog feel more comfortable and secure.
In this article, we’ll explore the reasons why dogs become aggressive, the signs to watch for, and practical strategies for dealing with and preventing aggression in dogs.
1. Common Causes of Aggression in Dogs
Aggressive behavior in dogs can have a variety of underlying causes. Understanding these triggers is the first step in addressing and preventing aggression. Here are the most common factors that contribute to a dog’s aggressive behavior:
1.1. Fear and Anxiety
One of the most common reasons dogs become aggressive is fear. A fearful dog may bite, growl, or display other aggressive behaviors as a way of protecting themselves from what they perceive as a threat.
- Signs of Fear-Based Aggression: A dog that shows fear aggression may exhibit signs such as cowering, tail tucked between their legs, ears back, and excessive barking or growling. They may also try to run away from the situation before becoming aggressive.
- Cause: Fear can be triggered by unfamiliar people, new environments, loud noises, or past traumatic experiences.
1.2. Resource Guarding
Dogs have a natural instinct to protect their resources—whether that’s food, toys, or even people. Resource guarding can result in aggression if a dog feels its possessions are threatened.
- Signs of Resource Guarding: A dog may growl, snap, or become defensive when someone approaches their food bowl, toys, or resting spot.
- Cause: This behavior is often rooted in survival instincts from a dog’s wild ancestors, who needed to protect resources to survive.
1.3. Territorial Aggression
Dogs are territorial animals by nature, and many will become aggressive if they feel their home, yard, or personal space is being invaded. Territorial aggression can be directed toward people, other animals, or other dogs.
- Signs of Territorial Aggression: Growling, barking, lunging, or snapping when someone enters their home or yard.
- Cause: Territorial aggression is often driven by a dog’s protective instincts, and can be particularly strong in dogs that have not been socialized well or have a dominant personality.
1.4. Pain or Illness
A dog that is in pain or suffering from an illness may become more irritable or aggressive. This could be due to discomfort or fear of further injury when approached.
- Signs of Pain-Induced Aggression: Growling, snapping, or biting when touched in a certain area, limping, reluctance to move, or a decrease in activity.
- Cause: Illnesses, injuries, or conditions like arthritis, dental problems, or ear infections can make a dog more sensitive and reactive.
1.5. Lack of Socialization
Dogs that are not properly socialized during their early months of life may struggle with interactions with other dogs, people, or new environments. This can result in aggressive behavior due to fear, confusion, or uncertainty.
- Signs of Aggression Due to Lack of Socialization: A dog that is aggressive toward strangers, unfamiliar dogs, or in new situations. They may bark, growl, or lunge at new people or dogs.
- Cause: Inadequate exposure to positive experiences with other dogs, animals, and people during puppyhood can lead to fear-based aggression in adulthood.
1.6. Dominance Aggression
Some dogs may exhibit dominance aggression, which occurs when a dog is trying to assert their authority over another dog, person, or animal in the household.
- Signs of Dominance Aggression: Growling, showing teeth, or aggressive postures when interacting with people or other pets. These dogs may try to take control over certain areas, such as the bed or food bowl.
- Cause: This can be driven by a desire to control resources or establish a pecking order within the household.
1.7. Protective Aggression
Dogs may become aggressive when they are protecting their owners or their family members. Protective aggression is often directed toward strangers or other animals that the dog perceives as a threat.
- Signs of Protective Aggression: Barking, growling, lunging, or biting when strangers approach their family members or when another animal poses a threat.
- Cause: This behavior is instinctual in many breeds, especially those that were originally bred to guard homes or flocks.
2. How to Recognize Aggressive Behavior in Dogs
Aggressive behavior doesn’t always mean biting or attacking. In fact, there are many warning signs that can signal that a dog is feeling aggressive or anxious. Here are some common behaviors to watch for:
2.1. Growling and Snarling
Growling and snarling are often early indicators that a dog is feeling threatened, anxious, or aggressive. While growling can sometimes be a playful behavior, in the context of aggression, it is usually accompanied by other signs, such as showing teeth or stiff body posture.
2.2. Lunging or Staring
Lunging or staring directly at a person or another animal can indicate that a dog is about to act aggressively. It’s important to understand the context of the behavior, as it could also be a sign of dominance or territorial aggression.
2.3. Raised Hackles
When a dog’s hackles (the fur along their back and neck) stand up, it’s a sign of heightened arousal or aggression. This behavior is often triggered by fear, excitement, or an impending threat.
2.4. Baring Teeth
Baring teeth is a clear sign that a dog is preparing to escalate a situation. It is often accompanied by growling, rigid body posture, and intense eye contact.
2.5. Ears Back and Body Stiffness
Aggressive dogs often have their ears pinned back against their head, and their bodies will appear stiff or tense. These are clear indicators that the dog is feeling threatened or confrontational.
3. How to Manage and Prevent Aggression in Dogs
While aggression in dogs can be a serious issue, there are ways to manage and reduce aggressive behavior. With patience, consistency, and proper training, most aggressive behavior can be addressed.
3.1. Consult a Professional
If your dog is showing signs of aggression, it’s important to seek help from a professional dog trainer or behaviorist. These experts can assess the root cause of the aggression and develop a tailored training plan to address the issue.
3.2. Socialization and Exposure
Proper socialization is key to preventing aggression, particularly in puppies. Gradually expose your dog to new people, animals, and environments in a controlled and positive way to build confidence and reduce fear-based aggression.
3.3. Positive Reinforcement
Use positive reinforcement to reward desirable behaviors, such as calmness around new people or animals. This can help your dog understand what behaviors are acceptable and encourage them to repeat those actions.
3.4. Avoid Punishment
Punishing a dog for aggressive behavior can escalate the situation and make it worse. Instead, focus on redirecting your dog’s attention to a more positive activity, such as sitting or playing with a toy, when they show signs of aggression.
3.5. Create a Calm Environment
Dogs that experience high levels of stress or anxiety may display aggression. Create a calm and secure environment for your dog by maintaining a routine, providing them with a safe space, and avoiding situations that may trigger aggressive behavior.
3.6. Vet Check
If your dog’s aggression seems to be related to pain or illness, take them to the vet for a thorough examination. Conditions like arthritis, dental problems, or infections can make a dog irritable and more prone to aggressive behavior.
4. Conclusion
Aggression in dogs can stem from a variety of causes, including fear, pain, territorial instincts, and lack of socialization. By recognizing the signs of aggression and understanding its underlying causes, you can take steps to manage and reduce aggressive behavior in your dog. Remember, addressing aggression takes time and patience, but with the right approach, most dogs can learn to behave in a more calm and manageable way. If you’re struggling with an aggressive dog, seeking the help of a professional trainer or behaviorist is often the best course of action.
FAQs
1. Can aggressive behavior be fixed in all dogs?
With proper training, socialization, and professional guidance, most dogs can improve their behavior. However, some dogs may require ongoing management, especially if aggression is rooted in medical conditions or severe trauma.
2. What should I do if my dog shows signs of aggression toward other animals?
If your dog becomes aggressive toward other animals, avoid situations where they might encounter triggers. Gradual, positive exposure to other animals and professional training can help.
3. How can I prevent my dog from becoming aggressive in the first place?
Early socialization, positive reinforcement, and consistent training are key to preventing aggression. It’s also important to address any behavioral issues early before they become problematic.
4. Can certain breeds be more aggressive than others?
Some breeds may have higher prey drive or protective instincts, which can lead to aggression if not properly managed. However, aggression is more about individual temperament and upbringing than breed alone.
5. Should I punish my dog for aggressive behavior?
Punishment is not effective in dealing with aggression and can make the situation worse. Focus on rewarding good behavior, and consult with a professional trainer if aggression persists.
Dog owners who have dogs with tendencies toward aggression, characterized by growling, a fighting posture, snarls, snaps, or lunges, should absolutely not bring them to public dog parks or any other public dog areas. These characteristics are threats. Additionally, if your dog exhibits these traits, make sure that you walk him with a choke chain collar. Normal nylon collars can easily snap, allowing the dog to get loose.
Some breeds of dogs do not like to be touched. Often, household family members may get bitten due to the handling of the dog. Handling problems are common in pet dogs. Aggression between dogs and children is a very serious problem. Therefore, dogs must be taught to accept and enjoy being handled. Otherwise, they may threaten or bite. Gradual exercises can desensitize dogs to being patted, hugged, grabbed by their collars, and so forth. It is imperative, however, if an owner has a dog who exhibits signs of aggression to begin obedience training immediately and keep the dog away from other animals and people until the threatening behaviors subside.
The laws of today hold dog owners negligent if their dog bites a person or another dog without provocation. The dog owner can be sued for the cost of medical bills, trauma to the individual or animal that was bitten, and any other incidentals caused by the bite. Home insurance covers these types of lawsuits; however, the increase in premiums is always significant and can be a reason for policy cancellation in some cases. Additionally, the dog that bites will normally be held for 10 days, tested for abnormal aggression, and listed in the county’s list of “dangerous dogs.” If the dog bites again, most state laws require euthanizing the dog.
