Reactive Dogs Are Not Aggressive: Understanding Dog to Dog Reactivity

Dog to dog reactivity explained. Learn the difference between reactive and aggressive behaviour and how to support reactive dogs.

Reactive dogs are often misunderstood. Loud barking, lunging, or sudden movement can look frightening, and many dogs are quickly labelled as aggressive. In reality, reactivity and aggression are not the same thing. Understanding the difference is one of the most important steps in helping a dog feel safer and behave more calmly in the world.

What is dog to dog reactivity

Dog to dog reactivity is an umbrella term for exaggerated responses that occur when a dog feels overwhelmed. This most commonly happens on the lead, where dogs are physically restricted and unable to create distance.

For some dogs, reactivity is defensive. Their behaviour is an attempt to say “this feels too much” or “please stay away”. For others, reactivity is driven by frustration. These dogs may want to approach another dog but feel blocked by the lead, causing emotions to spill over.

Although the emotional motivation can be very different, the outward behaviour often looks the same. This is why reactive dogs are so often mislabelled and misunderstood.

The benefits of understanding reactivity

When we recognise reactivity as an emotional response rather than disobedience, our approach changes. Instead of trying to suppress behaviour, we focus on helping dogs feel safer, calmer, and more able to cope.

Understanding why a dog is reacting is the key to helping them. When we support emotional regulation and reduce overwhelm, dogs no longer need to rely on exaggerated behaviour to communicate how they feel.

If your dog struggles around other dogs on walks, building understanding is the first step. My online course From Reactive to Relaxed supports guardians to recognise emotional triggers, manage walks safely, and help dogs stay under threshold.
