They're not trying to lecture you, they're trying to protect their hobby. People like you who think that "positive reinforcement" and a "no tolerance mentality" about fighting are the reason these dogs are getting banned in so many places. These dogs were bred to fight, its intrinsic to their very being. Keeping them together is taking a risk and thats a fact. If you dont want to listen then thats fine, but dont get all pissy at everyone bc theyre only looking out for the wellbeing of the hobby and more importantly the wellbeing of the dogs.
