Any dog can be raised to be sweet and loving, or neglected (or spoiled) enough to attack. Small dogs are usually the worst offenders, but when a chihuahua attacks, you push it away and put up a baby gate when company comes over. Pit bulls are often the sweetest dogs, however their size and build are menacing which leads people to be afraid. Also, when a large and physically intimidating dog attacks it is much more likely to do major damage. I wish I could have a pit, but they are forbidden by my HOA and home owners' insurance.
