About the Breed
The Mastiff is a colossal breed whose origins trace back to the earliest days of civilization. Massive in size and heavy in bone, this powerful dog is known for its courage and immense strength, yet it carries itself with calm dignity and a gentle, composed temperament. Despite its docile nature, the Mastiff is a formidable protector of those it loves.
A mature male stands at no less than 30 inches at the shoulder and may outweigh many fully grown adults. The body is rectangular, deep-chested, and thickly muscled, covered by a short double coat that appears in fawn, apricot, or brindle. The broad, massive head features a distinctive black mask, while a wrinkled forehead enhances an expression that is both alert and kind. Mastiffs are patient, affectionate companions who respond best to gentle, consistent training. Fiercely loyal to their families, they are naturally cautious around strangers, making early socialization and proper training essential. While magnificent companions, Mastiffs require serious commitment, as owning a giant breed of such power and size is a responsibility not to be taken lightly.
