Is my reactive dog aggressive?

Often not — reactivity is usually about fear, frustration or over-excitement rather than a desire to harm. A behaviourist can help you understand your dog’s triggers.

Can rest really reduce reactivity?

Yes — over-tired, over-stimulated dogs are far more reactive. Plenty of good-quality rest genuinely helps.

Do calming aids help reactive dogs?

Calming support can lower baseline arousal so your dog finds it easier to learn and cope, alongside a reward-based training plan.

Calming an Over-Excited or Reactive Dog

7 min read Vet-informed guidance

A dog that lunges, barks or 'loses the plot' at other dogs, people or movement is often over-aroused and struggling to cope, rather than being aggressive. Reactivity is common and manageable with patience, the right techniques and support. Here’s how to help your dog feel — and behave — calmer.

Understanding reactivity

Reactivity is an over-the-top response to a trigger — often fear, frustration or over-excitement. The dog’s arousal level spikes so high they can’t think or respond to you. The aim of management isn’t punishment; it’s helping them stay below the threshold where they tip over.

What it can look like

Reactivity has a recognisable pattern around triggers.

Lunging, barking or spinning at other dogs, people or traffic
Becoming 'glued' to a trigger and unable to focus on you
Struggling to settle after an exciting or stressful event
Pulling hard and a generally high state of arousal

Helping a reactive dog

Calm, distance and consistency are your tools.

Create distance from triggers so your dog stays under threshold
Reward calm focus on you with high-value treats
Keep walks predictable and avoid flooding them with triggers
Make sure they get enough rest — tired dogs are more reactive
Use calming support and consider working with a behaviourist

When to see your vet. A qualified, reward-based behaviourist is invaluable for reactivity. Your vet can also rule out pain (a common hidden driver) and discuss whether calming support would help your dog learn more easily.
