Why do some dogs attack and bite people?

There are many reasons why dogs attack. A dog may bite out of fear or to protect their territory or to establish their dominance over a person. Some owners actually teach their dogs that biting is an acceptable form of play behavior. This plays a role in the continued increase in newborns suffering serious injuries or getting killed by dogs who view them as "prey." Because dog bites occur for a variety of reasons, dog owners should take the steps necessary to try and prevent bites such as proper socialization, supervision, training, and safe confinement.
