Leash walking
Why does my dog lunge at other dogs on walks?
Last updated 23 September 2026 · How we write and check this
Short answer
Lunging at other dogs usually comes from one of two places, frustrated excitement at being unable to reach and greet a dog it wants to meet, or fear and a desire to increase distance from a dog it finds threatening, and the underlying cause matters for how you respond. Create distance immediately either way, and involve a qualified trainer if it happens often.
Reading the difference
A lunging dog with a loose, wiggly body and a high pitched, excited bark is usually frustrated at being blocked from a greeting. A lunging dog with a stiff body, low growl, and hard stare is more likely acting out of fear or a need to defend space, even though both can look alarming from the outside.
The immediate response
In the moment, creating distance quickly, crossing the street, turning around, or stepping behind a parked car, is more useful than trying to correct the behavior while it is happening. Once your dog is calmer and further away, you can work on training in a lower arousal state.
Why frequent lunging needs professional help
Leash reactivity that happens regularly, especially with fear based lunging, tends to need structured, gradual work that is genuinely hard to do correctly without guidance. A qualified trainer or behaviorist can assess the specific pattern and build a realistic plan rather than relying on trial and error.
Key takeaways
- Lunging can come from frustrated friendliness or fear, and the body language usually tells the difference.
- Creating distance immediately is more useful in the moment than trying to correct the behavior.
- A wiggly, excited lunge differs meaningfully from a stiff, growling one in what it signals.
- Frequent leash reactivity is worth addressing with a qualified trainer rather than trial and error alone.
