in life. However, it is still imperative for an owner to train their dog every day for a minimum of 10 minutes. More specifically, it is recommended for males to be neutered as this ensures that inherited aggression will not be passed on. It is suggested to use synthetic progestins with castration to reduce and eliminate aggressive behavior in dogs. Predatory and intermale aggression is inherent and related to testosterone secretion and as a result restrain, castration and the use of progestins are essential in reducing aggression in dogs. One study suggests that 40% of dominance aggression in dogs is a result of owners who provide basic levels of obedience training to their dogs. A dog is an owner's responsibility and it is necessary for the owner to establish leadership over the dog. A leash that is also known as a control line is critical in establishing and maintaining control. However other studies suggest that aversive means of control and training contribute to new and increased aggression rather than reduce it.
