I agree and disagree.. I had a sucky pitbull but his bitch.. I had to put her down after two litters. The breed is bred to be aggressive it’s not owner related it’s called prey drive. Instinct will always trump your skills. I also owned German box head pure bred Rottweilers. They are actually a working breed. You can breed it out but no guarantee no matter how good you think you are. I never owed one but boerboel is the same. South African Dutch mastif.. bred to be mean.!
