Aggression in Dogs (Overview)
Aggression in a dog is frightening. Not only for the person who is the apparent target, but also for the pet owner. The possibility that one might be the owner of a pet that has inflicted serious harm on another person is a nightmare. More than a million people are bitten by every year, and this is probably a very low number when you take into account all the bites that are not reported. Most bite wounds are minor, but dog bites account for one percent of all emergency room admissions. Half of the victims are also children, usually under 10 years of age.
Aggresive behavioral traits can pose significant problems if there are other underlying causes. Such traits are not usually predetermined by age, breed, or gender. However, if a young dog shows signs of these traits, it may be genetic in origin, and the condition could become a long-term issue. There is no cure for these personality traits, but there are ways to work with the animal to reduce incidents and to prevent behavior from becoming exaggerated.
Symptoms and Types
Many aggressive signs are accompanied by a fearful body posture and facial expression, and with submissive behavior. Some dogs exhibit these signs if they are cornered, feel like they cannot escape, or are provoked. There are many types of aggression, including interdog, dominant, defensive, possesive, territorial, predatory, parental and those induced by fear, pain, or punishment. Of these, signs of an offensive type of fear include:
Conversely, signs of defensive aggression include:
Aggressive behavior in dogs in mainly attributed to:
Pack order behavior
Aggression, fear, and defensive behavior may also be a normal response for some dogs, depending on the circumstances. Animals that were abused, roughly handled, or harshly punished have been known to exhibit some, or all, of these behaviors. In addition, living conditions play a role in aggression, as does being attacked or frightened by another aggressive dog, owners who spoil or praise too much, isolation from human contact, and being teased by children.
Understanding a puppy's growth periods may help in comprehending canine aggression. Beginning at 3 weeks of age until 14 weeks, puppies critically need socialization. (If you are purchasing a puppy, it is best to get it between the ages of seven to eight weeks old.) Puppies are very fearful between 8 and 10 weeks old and need to be handled gently by everyone around them (i.e., no harsh discipline at this age).
Adolescence sets in at about 14 weeks and ends when sexual maturity has been achieved -- about 15 months of age. If socialization hasn’t occurred by the time it is 14 weeks old, you may never be able to trust it around people or other dogs. From the beginning of adolescence to sexual maturity, puppies tend to bark at strangers and become more protective. Males begin to lift the leg to urinate during this period. It’s also important to introduce them to strangers in the home -- adults, children, and other dogs -- during this period.
Dogs that have been bred to be protective -- Dobermans, Akitas, and Rottweilers -- are more aggressive by their very nature. Dogs bred to kill small game, such as terriers, retain this characteristic. Non-neutered male dogs, females in heat, and females nursing puppies are also typically aggressive.
Then there is the dog's pack order. It is is built into the way they perceive the world. And body language is the tool for establishing a dog’s rank in the pack. It will look at you and your family as members of its pack and will try to establish its place by challenging the more submissive members, such as children. If the animal growls while guarding its food dish, discipline the behavior immediately. If these types of behaviors are not corrected, the dog will, little by little, gain dominance over some or all of the family members.
