Pain Aggression

• The first step when dealing with aggression in dogs is to have a vet run a thorough physical examination to rule out any conditions that may cause pain. In some cases, aggressive behavior may be triggered by health conditions, such as low thyroid levels.
  
  

Fear Aggression

• This form of aggression takes place in fearful dogs when they are cornered and have no way to escape. In some cases, this behavior may stem from a history of abuse.
  
  

Dominant Aggression

• This is the most common form of aggression and takes place when the dog believes itself to be ''alpha'' in the family. Weak owners and family members who are unable to provide leadership and are inconsistent in training their dogs are often victims of this type of aggression.
  
  

Territorial Aggression

• This is the typical type of aggression seen in guard dogs. This aggression takes place when a human or other animal invades the dog's territory.
  
  

Prey Aggression

• Dogs that have a strong prey drive will often chase anything that moves. Children, cyclists, joggers, and wild animals are often victims of these types of dogs.
  
  

Considerations

• Because aggression in dogs may stem from diverse causes, only an attentive dog behaviorist can decipher the dynamics that take place and help the owner undertake the right course of action. Aggression in dogs is a serious problem that, left untreated, is very likely to aggravate with time.
