You’ve worked with your dog on obedience training and socialization. And then out of the blue, your dog becomes aggressive toward another dog. Understanding why your dog may be aggressive helps in controlling the aggression. Your dog may be afraid of the other dog if it approaches too quickly or crowds your dog. Other times your dog may feel the need to dominate and protect us.  Dog owners are often surprised when their normally calm dog gets aggressive. Often dogs will follow your lead so if you are tense and fearful, your dog could act out. Sometimes owners will insist that the dogs say hello. You need to observe the behavior of both dogs. If either dog looks nervous or acts aggressively, avoid the interaction and step away to increase distance. Say something to the other dog owner if necessary and act with confidence.
