Reactivity in dogs refers to an exaggerated response to a stimulus, such as another dog, a person, or a loud noise. This behaviour can manifest as barking, lunging, growling, or even aggression.

Reactivity is often a result of fear, anxiety, or lack of socialization in dogs. It is essential for dog owners to understand the underlying causes of reactivity in order to address and manage this behaviour effectively.

Reactivity can be triggered by various factors, including past negative experiences, genetic predisposition, or learned behaviour. Positive reinforcement techniques and desensitization strategies can help dogs learn to remain calm in challenging situations and overcome their reactive behaviour.
