As usual, Carrie has advice I'd have never thought of but will definitely try! Aussieshep, what you're describing with Guinness bolting to greet other dogs is something our Aussie Eli does all the time as well, and we have yet to break him of this. Just as you say, it's not a threatening action but it can be scary for the other dog and its owner. Eli goes bounding over, wiggles his butt, gets into a play bow, and then runs back to us--and all the while we look like idiots yelling at him to return. He's such a friendly guy, though, that we don't want to discourage his "making friends," we just want a bit more control over him when he does!

Thanks for the help, Carrie

and good luck with Guinness!
