Some dogs bother chickens and some don't. It sounds like the dog is not yet on your property. So actually, the dog is not yet a problem.
I solve the issue of neighborhood dogs by having a good fence around my property. Then the dogs can't get onto my property.
Please instruct your son to never swerve about animals in the road. It is not worth wrecking his car, injuring himself, or perhaps hitting another car and injuring someone else. Also, the very best way to not hit wildlife is to maintain the exact same course and speed. The animal then can judge how to move out of the way. If you swerve, you are almost certain to hit them.
