It's not the breed's fault it has a bad rap, it's the fault of the irresponsible owners that don't train and socialize their dogs. Those are the ones that make front page news and pound into everyone's head that all pitts are bad.

You are taking the right path to insure your pup is a wonderful all around dog. Training is perfect because not only will he be trained and will be a more of a joy to have around, (because he won't have bad habits) but he'll also get the socialization he needs to be a great dog buddy to other
dogs Big and Small!!
Keep him around people, take him everywhere you can let him see tons of different people!! Big, small, old, young... Let everyone pet him and hold him, and play with him.
I hope to see pictures soon!!
