Aggressive or violent dogs may have causal reasons for doing so.
A well-behaved dog is generally a jovial dog, so learning the source of aggression in canines is essential to your pet and also to the general safety of yourself and those around you.

• Dominance Aggression
Establishing dominance is the reason for dogs to have violent acts of aggression.
This may be displayed to humans but is much more common towards other pets or animals.
Canines are pack animals and they think of their human family as their pack.
Combatant behavior might occur if ever there are people present that they do not consider a part of the pack.
This aggression can be prevented or changed with early training to establish dominance over your dog.

• Territorial Aggression
Territorial aggression is also a problem for some canines.
They make their homes and family a very important possession and will try to protect them furiously.
They can sense it when their territory has been invaded and the family is threatened.
There are reasons why they act that way but still not accepted and not desired by humans.
Making sure you are the "leader" of the pack in your dog's eyes will relieve them of the duty of being the guard dog or Alpha dog of your pack.
This often stops the canine aggression.

• Fear Aggression
Fear is another contributory factor of why canines manifest aggressive behavior.
There are indicators that a dog might be afraid of something and should be taken seriously.
When dogs are in the position of fear, it exhibits behaviors such as growling, ears pulled back and tail between thighs.
Never approach a canine in this state.
Instead, eliminate the cause of the fear first.
Once you see the canine relax, it is safe to go to the dog.
If fear is the reason behind your dog's aggression, training should be done to make your dog more confident in non-threatening situations.

• Predatory Nature
Other dogs when in fear settle in predatory behavior.
They are used to hounding and playing games occasionally with cats, with other smaller canines or children.

• Redirected Aggression
One reason also for hostile behavior in your canine is redirected anger, and very seldom understood.
This occurs whenever a canine can't blurt out its anger on the definite object rooting the fear, territorial thoughts and other feelings.
For example, if your dog is in the yard and someone they think is a trespasser enters the house, your dog may turn on someone else.
Many do not understand this because they aren't aware of the root cause of the presented behavior.

• Medical Reasons for Aggression
There can be medical conditions that might cause animals to display aggression.
Sometimes, females are very violent when nursing or pregnant.
Even if maternal protectiveness is usual in females' aggression, they can be controlled through training in early stages.
In order to learn the reasons for aggressiveness, it is important to know about the training methods which can be utilized to become more efficient.

Knowing the reason for your dog's hostility will help you take control of the situation and find ways of giving your pet the best quality care.
You develop a happier and healthier relationship with your pet and ensure the safety of anyone who comes in contact them.
