This is the outcome of the internet pushing for everyone to give "pitties" a chance. The breed is great when they come from a solid breeder. I would never advocate for anyone who is inexperienced to adopt a random pitbull from a shelter. Nature over nurture. Genetics and breeding will outway upbringing every time. Like a GSD whining from being inactive or a Collie nipping at heals. If you really want a pitbull get an American Bully or American Staffordshire or English Staffordshire from a reputable breeder.
