Study: Dogs React To Aggression With Aggression
According to a year-long research study of dog owners conducted by researchers at the University of Pennsylvania found that dog owners who use confrontational training methods are encouraging those dogs to reciprocate with their own aggression.
The study is based on surveys completed by 140 dog owners; it found that 43% of dog owners hit or kick their dog for undesirable behavior, while 41% growl at their dog. Another 39% physically force the release of an item from the dogs mouth, 31% “alpha roll” the dog, 30% stare down the dog, and 26% grab the dog by the jowls and shake the dog.
This study clearly showed that dogs respond to aggressive tactics with increasingly aggressive behavior. On the other hand, they very rarely respond aggressively when the training techniques are modified to include non-aversive or neutral methods, such as additional exercise or rewards.
