Reactivity isn't random. It's often man-made.
That squeaky tennis ball your dog goes mad for isn't just a toy to them. The squeak mimics a dying animal. Yes you read that correctly!
A simple game of fetch is a predator and prey game, played daily, and it's one of several everyday habits that can quietly build reactive behaviour over time.
Most reactivity we see at Extremus isn't fear anymore. It's habit. The dog has learned that barking, lunging or reacting gets a result, and it no longer needs the original trigger to keep doing it.
The fix is structure and leadership.
Rethink playing constant, high arousal games like fetch and tug
Give your dog a job or purpose, not just total freedom - leadership is crucial
Build daily, consistent management into every interaction, not just training sessions
We see this every week on our residential programmes and tailored 121's, dogs of every breed, every age, all landing in the same place - over stimulated, hyper aroused and totally empowered.
What's your dog's biggest trigger right now?
