Our 13 wk BC walks perfectly off the lead whilst in the woods/fields, but as soon as she's out on the lead near a road, she is drawn to chasing cars!
I have sat for hours on the bench at the side of the road to try and get her used to the traffic but I get the same reaction every time a car goes by

I had a friend drive by and pull up to talk to us a few times and as soon as the car gets close enough, she starts wagging her tail, (the dog, not the friend

) making no attempt to go for the car.
I have heard that this is a common problem with Collies and just wondered if anyone had any similar experiences, and if so, how did they cope?
I think I will end up with muscles like Arnie if this carries on!
