Good idea, JenEllen. Might try that one. Really, am not trying to train them, just want to find a good way to get out of the situation without 1. Having MY dog killed, 2. Having my husband get into a fight with the owner, if i have to spray his dog. Oh yeah, to the uninformed: You want pepper STREAM, not spray. Spray can backfire in any breeze, and nail YOU.
Anyone have experience with the sonic gizmos? Might give our own dogs a headache, but again, better that than dead.
