Focus on the shock collar use, damage, and lack of clarity from the trainer in the story, not necessarily the name of the company. You must trust the person and techniques used for your dog. Sometimes we get frustrated with Fido and think the quickest results are the most effective. That’s not always true. Zapping them into submission can be dangerous and can cause fear and aggression. I’d prefer to associate my dogs and client’s dogs with positive things like treats, affection, and play instead of pain.
