About the Mastiff:
Mastiff information, advice,
answers and dogs facts

Mastiffs are natural guard dogs, they will protect their family without special training to do so. In fact training the dog to be aggressive will have a negative affect on them, aggression and protectiveness are not the same. This breed should be thoroughly trained and socialized from a young age to keep them from being shy. Because of their eventual giant size care should be taken not to allow a puppy to do anything you wouldn't want a 150 lb adult to do (like jumping up on the furniture or jumping up to greet you).
