Some Techniques Triggered Aggression

The highest frequency of aggression occurred in response to aversive (or punishing) interventions, even when the intervention was indirect:

• Hitting or kicking the dog (41% of owners reported aggression)
• Growling at the dog (41%)
• Forcing the dog to release an item from its mouth (38%)
• "Alpha roll" (forcing the dog onto its back and holding it down) (31%)
• "Dominance down" (forcing the dog onto its side) (29%)
• Grabbing the jowls or scruff (26%)
• Staring the dog down (staring at the dog until it looks away) (30%)
• Spraying the dog with water pistol or spray bottle (20%)
• Yelling "no" (15%)
• Forced exposure (forcibly exposing the dog to a stimulus – such as tile floors, noise or people – that frightens the dog) (12%)

In contrast, non-aversive methods resulted in much lower frequency of aggressive responses:

• Training the dog to sit for everything it wants (only 2% of owners reported aggression)
• Rewarding the dog for eye contact (2%)
• Food exchange for an item in its mouth instead of forcing the item out (6%)
• Rewarding the dog for "watch me" (0%)
