Your walks have become a source of dread. The moment your dog spots another dog — across the road, through a fence, or at the dog run — they lunge, bark, and strain at the leash. This behaviour, known as leash reactivity or inter-dog aggression, is one of the most common reasons Singapore dog owners seek professional help.
What Is Dog Reactivity and Why Does It Happen?
Reactivity describes aggressive or over-aroused behaviour directed toward other dogs. Dogs displaying reactivity are typically trying to create distance between themselves and the trigger — the other dog. It’s a communication strategy rooted in either fear, frustration, or learned response.
Some dogs that seem “aggressive” on leash are actually frustrated greeters — dogs who desperately want to interact with others but, constrained by the leash, express that frustration through barking and lunging.
Is Reactivity Normal?
Some degree of excitement or alertness around other dogs is normal. However, when the behaviour is intense, generalises to all dogs, and makes outdoor walks unmanageable, professional intervention is warranted. Left untreated, reactivity tends to escalate over time.
Avoid These Common Mistakes:
- Asking your dog to “sit and stay calm” while the other dog passes — this creates even more frustration
- Assuming it is playful excitement — it rarely is
- Avoiding all walks — this worsens isolation and anxiety
Could Pain Be Involved?
Yes. Pain is an underappreciated driver of reactivity. A dog experiencing physical discomfort may become more defensive and reactive. A full veterinary check to rule out musculoskeletal or other pain is always an important first step at Beecroft.
Treatment and What to Expect
Treatment typically involves systematic desensitisation and counter-conditioning — gradually changing your dog’s emotional response to other dogs from negative to neutral or positive. Environmental management (choosing quieter walking routes, adjusting timing) supports the process. For dogs with high anxiety or impulsivity, medication can significantly accelerate progress.
The goal is not necessarily for your dog to love every dog they meet, but to walk past other dogs calmly. With the right support, this is achievable for the vast majority of reactive dogs in Singapore.
