San Diego Mastiff is a dedicated breeder of exceptional Neapolitan (Italian) Mastiffs located in sunny San Diego. Our dogs are raised on four acres of open space, where they are free to explore, play, and develop both physically and mentally. We prioritize love, socialization, and hands-on care, resulting in dogs with calm, friendly, and well-balanced temperaments. Our mastiffs, Biggie and Lulu, have been raised around young children and are known for their gentle, patient nature, making them excellent family companions.
