Is my dog reactive, or just excited?

“He just wants to say hi.” Sometimes that is true. The dog who drags you toward every other dog with a wagging tail is frustrated, not aggressive. But frustration on a leash looks a lot like aggression to the dog across the street, and to that dog’s owner, and after enough bad interactions it can turn into the real thing.

Three flavors of reactivity

• Frustration: the dog wants to get to the trigger and cannot. Loose, wiggly body, high tail, whining. Common in social dogs who went to daycare.
• Fear: the dog wants the trigger to go away. Stiff body, weight back, barking that gets louder the closer it comes. Often starts after a scare.
• Aggression: intent to make contact. Hard stare, forward weight, low growl, silent lunge. Needs an experienced trainer, and needs it soon.

Why the label matters less than you think

All three dogs have the same missing piece: they cannot stay calm and think when the trigger appears. The plan is the same foundation for each of them. Build a structured heel and a reliable place. Build impulse control. Then introduce the trigger at a distance the dog can handle, reward calm, and shrink the distance over days and weeks in real environments.

What changes is the pace, the distance and the tools. That is Seth’s call after seeing the dog, which is why an in-person assessment is part of every behavior case.

What not to do

Do not let the dog rehearse it. Every explosion on leash strengthens the pattern. Cross the street, add distance, keep the walk short and structured until you have a plan. And do not try to fix it with treats alone from a foot away; a dog over threshold cannot eat, let alone learn.

Reactivity is Seth’s specialty. Most dogs need the three weeks of Platinum: enough time to build the foundation and then practice calm around real dogs and real people, every day, in a home environment.
