Before we start getting upset at the parents for letting their baby approach a pit bull like this, let's consider a few things. Pit bulls are not predisposed to be aggressive or vicious. Those characteristics are only introduced when owners train the dogs in such a way. According to the ASPCA, socialization plays a critical role in training a dog to be happy and friendly, especially when keeping company with other dogs. Pit bulls are, of course, no exception to this guideline. Pit bulls have every ability to be loving, family dogs as long as they are brought up in an environment that fosters those ideals.
