Fear Aggression in Dogs
Many types of aggressive behavior in dogs are rooted in fear. The good news: You can reduce your dog’s fear and the aggressive behavior.
Fear-related aggression most frequently appears between the ages of eight to 18 months, as a young dog reaches maturity. This may be because increased boldness tends to come with maturity. But it’s also likely because, over time, aggressive responses are reinforced; the scary stimulus (most often a human, when we’re talking about aggression issues) backs off. Initially, a fearful pup generally tries to hide from scary humans by moving away, perhaps crawling under a chair.
