Are you struggling with a dog that goes wild whenever they see another dog or a person passing by? You are far from alone. Reactivity is one of the most common problems we see at our residential centres, and the good news is that it can be managed, and often greatly reduced, with a consistent plan.
What is a reactive dog?
A reactive dog responds to everyday triggers (other dogs, people, bikes, cars) with more intensity than the situation needs: lunging, barking, growling, spinning or pulling hard on the lead. It is usually driven by fear, frustration or over-excitement. It can look like aggression, but many reactive dogs are simply overwhelmed.
Why is my dog reactive on the lead?
- The lead takes away choice. A worried dog can’t move away, so it tries to make the trigger go away instead.
- Frustration. Some dogs desperately want to greet and learn that barking is what happens when they can’t.
- History. One bad encounter, or a lack of calm socialisation as a puppy, can colour every walk after.
- Pain. Sore joints, ears or teeth make any dog shorter-tempered. If reactivity appears suddenly, see your vet first.
How do I manage a reactive dog on walks?
- Find the threshold. Notice the distance at which your dog can see a trigger and still take a treat. That is where training happens.
- Create distance early. Cross the road, step behind a parked car or turn around with a cheerful cue before your dog tips over.
- Reward the look, not the lunge. When your dog glances at a trigger and stays calm, mark it and reward. Calm becomes the habit.
- Choose quieter times and routes while you build skills, so your dog isn’t rehearsing the reaction every day.
- Keep your lead loose and your voice calm. A tight lead tells your dog something is wrong.
- Never punish a growl. It is a warning. Punishing it removes the warning, not the feeling behind it.
- Use safe equipment. A well-fitted harness or flat collar, and muzzle training if there is any risk of a bite.
Can reactivity be cured?
Many dogs improve dramatically: they notice triggers, stay calm and move on. Some will always need a bit of management, such as giving other dogs space on narrow paths. How long it takes depends on the dog, how long the behaviour has been practised and how consistent the training is.
When should I get professional help?
If your dog has bitten, the reactions are getting worse, or walks have become something you dread, get help. On our residential courses, on-lead reactivity is covered from the Standard course, dog reactivity and aggressive on-lead reactivity on the 15-day Advanced course, and people reactivity and dog aggression on the 20-day Reactivity course. Every course ends with a handover lesson, so you learn to handle your dog the same way at home.
Key takeaways
- Work at a distance where your dog can still think.
- Reward calm glances at triggers.
- Manage the environment so your dog stops rehearsing the reaction.
- Rule out pain, and get expert help early if there is any risk of a bite.
