Aggressive Dog Breeds: Does Size Matter? -

Aggressive Dog Breeds

An aggressive dog breed is one that exhibits behavior such as biting, growling, snarling, showing teeth and charging at a person. There are many reasons why a dog would exhibit such behavior, such as when protecting a family member, when it sees an intruder, is fearful, in pain or when protecting its possessions. Some dogs are more aggressive than others.

Types of aggressive breeds & their behavior

How aggressive a dog is can be attributed to its genetic makeup a well as how it is raised and trained. A puppy from a breed that is known to be aggressive can be raised to be less aggressive while a less aggressive puppy can be raised to be extremely aggressive.

In some cases, aggressiveness in dogs has been associated with size of the dog, with large ones such as Pit-bull, Terriers and Dobermans being considered aggressive. This is because due to their size, their aggressiveness is more portrayed than that of smaller dogs. However, this has been refuted by scientific research with smaller dogs displaying more signs of aggressiveness than the bigger ones.

Some of the aggressive dog breeds include:

  • Dachshund - This breed is considered the MOST aggressive dog breed according to research. The breed is known to hate strangers and biting or attacking their master. They are also NOT friendly to children. However, its biting doesn't really cause serious harm.
  • Chihuahua - Another small sized dog that people may not consider harmful, the Chihuahua is also aggressive and there is a higher chance of it biting you than there is being bitten by a dog such as a Rottweiler.
  • Jack Russell - This dog does not like being rough handled and it may end up fighting. It can be aggressive to children who handle it roughly or to other dogs. The situation can be controlled by training and allowing the dog to run and practicing with it.
  • Chow Chow - Although attractive with fluffy hair, this canine is also aggressive. It does NOT associate well with children and therefore it should not be left alone with them and it does not play well with unfamiliar dogs. The Chow Chow is devoted to its owner and does not let a stranger approach its master. It also defends its territory.
  • Pekingese - Despite its small size, this breed is aggressive, especially toward strangers, small children and other dogs. It is also aggressive toward other people except its master, to whom it is attached.

Positives for Aggresive Dog Breeds

The aggressive nature of these dog breeds can be used to an advantage. Breeds such as Chow Chow, Chihuahua and Dachshund make good guard dogs and watch dogs if properly trained  and socialized  well from when they are puppies. They possess the characteristics required for warding off intruders while at the same time they can be great at home pets. However, other than the socialization and training, it is important for these pooches to view their owner as the pack leader. 

To learn how to be a pack leader, you can use the information provided by Doggy Dan on his website where he explains that the best way to gain the confidence and trust of a dog and to train it is to take the position of the pack leader. The information is accessible by a monthly subscription.

The importance of early, consistent training

Aggressive behavior in dogs can cause harm to people and other dogs. This is because these dogs tend to bite or exhibit other aggressive behavior such as growling, snarling, showing teeth and charging at a person. It is therefore important to ensure that a dog with aggressive tendencies is given consistent training and socialized from puppy-hood. As the master, you should take the position of pack leader and your canine should NOT be allowed to have a dominant status over any family member. A pooch that knows its social ranking can be good to family members, including children.

For the puppy

Aggressive behavior can be prevented by socializing your puppy early. Some of the activities include hand feeding your puppy, both by children and adults. The puppy should be trained  not to lunge or grab food. It should also not be allowed to jump on people, mount legs, chase children or growl. It should not be part of aggressive play such as wrestling and hand fighting.

To make sure that the aggressive behavior is not reinforced, the puppy should not be punished physically for being aggressive, but the vice should be discouraged by being trained alternative behavior or be restrained from repeating the act.

A puppy should be discouraged from jumping on children or biting them. If it happens, then children should refuse playing with it and tell the puppy to get off.

The puppy SHOULD be allowed to interact and play gentle games with children in activities and it should be trained  o feel as part of the family pack. 

For the older dogs

Training to curb aggressive behavior should go on even when the dog becomes older. It should be given praise when it behaves well and be disciplined if it behaves badly. The dog should be trained to obey the owner, so that it can see the owner as the boss. The owner should make sure that he/she wins if there is any confrontation with the dog. Allowing the dog to win can make it feel superior and increase its aggressiveness. It is not a good idea to leave children with dogs unsupervised.


Particular breeds of dogs tend to be more aggressive, a situation that makes them a danger to the family, especially if the aggression is directed toward family members to whom it is supposed to protect. However, the aggression of these breeds can be used constructively and the dog can become watch or guard dogs. This can be possible if the puppy is properly trained and socialized early so that it does not exhibit too much of its aggressive abilities. Learn more training techniques at websites like
