I am in no way telling people to be afraid I just would love for people to do there research before getting these types of dogs…again so my point is clear genetics DOES play a role and it is not all in how you raise them. Yes it helps curb canine aggression but won’t be the solution. This is not an attack I was not the one accusing someone of having a “tough” macho dog. I am just trying to get through to some people to please do your research. These dogs were bred this way for hundreds of years you just can’t train it out of them but you can curb it. Just be responsable.
