On of my kennel club friends owns 9 (Wilber being my favorite
) The first time I visited they ALL happily greeted me not one was aggressive and I had only met maybe 2 of her Bostons outside of her home at my class or at Confo Shows. Its not only how there raised its also breeding. I personally have never met an aggressive Boston. A Friend of mine also just rescued an abused Boston that although over sized with a little longer face is the perfect Boston temperament. Just be sure to find you a reputable breeder or rescue.
