Thanks for the excellent suggestions I will be sure to try them out It does work to get his attention off the cars...he still chases them a bit but has improved greatly. And he paws at his leash too like every minute. I will try rewarding him with a toy maybe he'll respond to that, I doubt it but it's worth a try. I have a toy in mind (his frisbee) but I don't think he'd like it if he could only use it then...but then again if I practise often enough he'll get to play with it a lot. Another thing is if I was to change the lead he'd chase the cars more again because I've tried a halter and just a regular leash and he chases them and jumps at them more than he does with the new lead. Oh well I'll just have to try my best.
