i mean in all honesty you never know what could happen with dogs, they're literally another human being with a different mindset, you could treat them to be the best nicest dog ever but they could do one bad thing because they wanted to do so or they got triggered to do it. But treating them does definitely impact on how they behave. If you haven't seen that guy who owns the pitbull HULK he literally trains these dogs to attack people and guard only his family and those dogs are used to that only and will abide by that but look at the fucking size of them bruh
