Our Border Collie is taking off after vehicles, is an e-collar the route to go? 

Our 3-year-old border collie, who's always high drive, has taken to lurching out after vehicles. It started with rattly trucks with trailers, and not its even noisy vehicles. He can be fully engaged and still reacts. It seems to be the sound and motion. Is an e-collar the route to go? He'll also take off if there is a bouncy ball e.g. basketball or tennis going on too? I don't see how we can engagement train him off this and it's life-threatening for him as he reacts and chases the moving vehicles. Thanks!

The taking-off is on-leash. He's on a leash or long line almost all the time. I give him (very) limited time off it to engage with other dogs periodically. He does recall from these situations but only if they are very limited in number or he gets a bad habit of "forgetting" recall. He's not super great socially, if I'm throwing a ball he gets pretty aggressively protective of it (and possibly me)

Thanks for the feedback on the e-collar. That's what I was kind of thinking, that it has to be "managed" or it could make things worse.

There are some good dog behavioral people here and it may be worth it before just getting a collar. I'm going to reach out to them.

I guess this is what you get from a border collie coming from a ranch lineage. Smart and driven :-)
