Desiree- That sounds like a perfect example of improper use and lack of training/understanding on her part. You are right about the triggering, especially when actual aggression is taking place. It also sounds like your friend or acquaintance was using the collar for correction. I don’t really believe in that. My other take on that is, if she does not have control over her dog around other dogs, she shouldn’t be putting her dog in that situation in the first place with or without an e-collar. BK
