Description: These self-confident, calm dogs are pretty tough on themselves and have a high pain threshold. True to their breeding as hunters, Mastiffs are very territorial. These dogs are intelligent, watchful, dignified and gentle toward their family/owners/handlers.
Their affectionate nature belies their size and these dogs absolutely, positively need love from their family/owners/handlers – even if being used as a guard dog. Thus, Mastiffs are not good outdoor dogs.
These dogs can show some insecurity when away from their territory, so socialize your Mastiff early to different environments.
