Although Pitt Bulls may have beed bread to display aggressive behaviour, that does not mean that every Pitt Bull born is going to be aggressive. In many cases irresponsible individuals acquire Pitt Bulls and then fail to handle them responsibly. A Pitt Bull in most cases that is raised with love and proper care is in turn going to be a beautiful Family Pet. I have seen this in many instances. This does not mean that the dog must be taken for Special Training.
Raise a dog responsibly an you will get the required results. I do agree with your Golden's characteristics and argument.
