While any dog can be aggressive due to poor breeding or training, some breeds have a genetic tendency towards territoriality and dominance. You’ll want to be extra cautious if any of the dogs on this list catch your eye. These pups may look cuddly, but they pack a mean bite if not properly socialized and handled from an early age.

If you’re not an experienced dog owner, you may want to consider a breed with a friendlier reputation. But if you’re determined to take on the challenge of training one of these feisty breeds, be prepared to take the alpha role and lay down the law to keep your aggressive hound under control.

What Makes a Dog Aggressive? Key Factors That Contribute to Aggression

What Makes a Dog Aggressive_

Aggression in dogs often comes down to a combination of factors. Genetics and individual temperament play a role, as some breeds have been specifically bred as guard dogs, hunting dogs or for sport fighting.  However, factors like home environment, upbringing, training and socialization are also hugely significant.  Some of the key factors that contribute to aggression in dogs are:

Lack of socialization  

Puppies need positive experiences with people and other dogs in their first few months to learn good behavior. Without this exposure, they can become fearful or reactive in their later life whenever they are around too many people or other dogs.

Abuse or neglect  

Dogs that have been mistreated may become aggressive as a defense mechanism. They need patience, consistency, and lots of TLC to overcome past trauma.

Health issues  

Sometimes aggression arises from an underlying medical condition such as hypothyroidism, ear infection, and chronic pain due to hip dysplasia and arthritis. It’s a good idea to rule out issues like arthritis, dementia, or any physical causes with a vet checkup if you bring home an elderly dog with a history of aggresion.


Some dogs are naturally inclined to guard their home or yard such as rottweilers, Belgian Malinois, German Shepherd, Cane Corsos and so on. With consistent training from an young age and by teaching them to be less territorial, you can curb the aggressiveness.

While certain breeds may be predisposed to aggression, there is no such thing as a “born bad” dog. With the right kind of care, training, and attention, even dogs with aggressive tendencies can become well-adjusted and trustworthy companions.

The most important thing is to understand what factors motivate your dog’s behavior so you can address the root cause, not just the symptoms. With time and patience, an aggressive dog can be rehabilitated.

    Tips for Responsibly Owning and Caring for Aggressive Dog Breeds  

    Owning and caring for any dog, especially those with a tendency towards aggression requires responsible ownership and commitment. Here are some tips for responsibly owning and caring for aggressive dog breeds:

    Tips for Responsibly Owning

    Early Socialization

    Start socializing with your dog from a young age. Introduce them to a variety of people, animals, and environments in a positive and controlled manner. This helps them develop appropriate social skills and reduces the likelihood of fear or aggression in unknown situations.

    Consistent Training

    Enroll your dog in obedience training classes or work with a professional dog trainer who has experience with aggressive breeds. Positive reinforcement methods are effective in shaping desired behaviors and building a strong bond with your dog.

    Proper Exercise and Mental Stimulation

    Provide your dog with regular exercise and mental stimulation to prevent boredom and frustration, which can contribute to aggression. Engage in activities such as walking, running, playing fetch, or puzzle toys that challenge their minds.

    Secure Fencing and Leash Handling

    Ensure that your property has secure fencing to prevent your dog from running away and potentially causing harm to others or themselves. When walking your dog, use a sturdy leash and be in control of their movements to avoid potential conflicts with other animals or people.

    Responsible Management

    Be aware of your dog’s triggers and take steps to manage their environment accordingly. For example, if your dog becomes reactive around other dogs, avoid situations where they might encounter unfamiliar dogs without proper supervision.


    Consider spaying or neutering your dog. This can help reduce aggressive behaviors associated with hormonal changes and can contribute to overall better behavior and temperament.

    Positive Reinforcement

    Use positive reinforcement techniques to reward good behavior and discourage unwanted behaviors. Reward-based training methods build trust, strengthen the bond with your dog, and promote a positive learning environment.

    Supervision and Safety Measures

    Always supervise your dog when they are interacting with children, strangers, or other animals. Use caution and take necessary safety measures to avoid any potential incidents.

    Research on the breed and Consult a Professional If Necessary

    You should also read books, watch youtube videos, and consult with professionals to educate yourself about dog behavior, aggression, and responsible ownership. Understanding your dog’s needs and body language will help you address any potential issues as soon as possible.

    If you are having trouble curbing your dog’s aggression or if you have concerns about their behavior, consult a professional dog behaviorist or trainer. They can provide professional advice and training techniques tailored to your dog’s specific needs.

    Remember, responsible ownership and care are for any dog breed, and it’s important to address any behavioral concerns quickly and professionally. With time, patience, and consistency, even naturally aggressive breeds can become beloved family pets. But they require training and monitoring to keep their behavior in check. So what do you think?
