A fence prevents normal approach and retreat while encouraging running and repeated visual contact. Barking, charging and stiff movement can intensify even between dogs that behave differently elsewhere.
Start with the full picture
Observe before the dogs reach the boundary and stop repeated rehearsal. Hands and faces should stay away from gaps where redirected bites are possible.
What to compare
| Observation | What to note |
|---|---|
| Build-up | How early do speed, tail height and vocalizing increase? |
| Barrier | Can either dog move away from the fence? |
| Recovery | Does arousal continue after visual contact ends? |
A low-pressure next step
Create distance, block the view and use separate yard times when needed. Do not arrange nose contact through openings.
Example in context
Two dogs race the shared boundary and become harder to call away with every pass. A visual barrier and coordinated schedules reduce the repeated pattern.
When to ask for help
A qualified professional can design safe management. Any bite or injury needs appropriate medical or veterinary care.
