Most important things to remember:
1. do not get anxious or yell at your dog.
2. Break the stare and redirect their attention (and reward them when they do! Click and treat for looking away from the other dog)
3. Move away from the stimuli if needed.
4. Be safe and aware of your dog's behavior and surroundings.
