A fast, straight approach can create social pressure even when the approaching dog is excited rather than hostile. Speed, tension and the recipient's response determine whether to interrupt.
Start with the full picture
Watch both sides. The recipient may slow, turn away, tuck the tail or freeze before any vocal response, especially in a doorway or on lead.
What to compare
| Observation | What to note |
|---|---|
| Speed | Is the approach controlled and interruptible? |
| Posture | Is the body loose or forward and stiff? |
| Recipient | Does the other dog approach, pause, avoid or seek cover? |
A low-pressure next step
Call or guide the approaching dog away early and create a wider path. Do not wait for the recipient to growl before protecting space.
Example in context
An off-lead dog runs straight toward a leashed dog that stops and turns its head. Interrupting the approach respects the leashed dog's limited options.
When to ask for help
Use qualified training support for unreliable recalls, repeated rushing or conflicts. Sudden changes in movement or social tolerance need veterinary assessment.

Blue Cross: why dogs wag their tails provides background for reading this pattern. A wag alone does not prove that an approach or interaction is welcome. This guide is an observation aid, not a diagnosis or a promise that every dog uses the signal in the same way.
