History & Origin of the Mastiff
“Mastiff” refers broadly to a group of large, molosser-type dogs with a noble lineage. The most recognized variant is the English Mastiff.
The English Mastiff’s roots trace back to Europe, with development solidified in 19th-century England.
Historically, mastiffs were used for guarding estates, as war dogs, and in combat roles. Over time, breeders selected for gentler temperaments to make them better family guardians rather than fighting animals.
Today, the English Mastiff is the archetype of the “mastiff” in many countries. Other types include the Tibetan Mastiff and Neapolitan Mastiff, each with unique characteristics.
Size, Life Expectancy & Physical Traits
Size & Physical Traits
Male mastiffs typically reach 30 inches (76 cm) or more at the shoulder, while females are around 27–28 inches tall.
Weight ranges from 150–200+ pounds (68–90+ kg). Coat is short, dense, and available in fawn, apricot, or brindle — always with a black mask.
Mastiffs drool heavily, snore loudly, and can produce strong odors due to their facial structure.
Lifespan
Mastiffs live around 8–10 years on average
With excellent care, some can reach 12 years. Regular vet visits and good nutrition make a big difference.
Temperament, Training & Socialization
