The line between reactivity and aggression can be blurry, and the solution for your dog will depend on their unique personality, experiences, and triggers. Reactivity and aggression are both situational behaviors that depend largely on the dog, and telling the difference between the two isn’t always straightforward. Your dog experiences reactivity whenever they respond to a situation (or a trigger) in a more intense way than you would expect, like overreacting to a sound or the presence of another person or animal. For some dogs, their reactivity can look like aggressive behaviors, like growling or lunging. Many reactive behaviors are mistaken for aggression. Aggression is the threat of harm to another individual, and these behaviors can include: Snarling, Growling, Snapping, Biting, Barking, Lunging. Animals will generally try to prevent conflict, not create it. If an animal has resorted to aggressive behaviors like biting or lunging, it's likely because their more subtle, lower-level stress signals have been missed or ignored. When exposed to a trigger, every dog has a specific threshold they can handle before their behavior becomes erratic. Before your dog reaches their threshold, distance is your best friend. Creating separation between your dog and their trigger helps move them into a calmer state.
