Get to Know Mastiffs

  • World's Heaviest Dog: The heaviest dog ever recorded was an English Mastiff named Zorba, who weighed 343 pounds.
  • Ancient Warriors: Mastiff-type dogs accompanied Roman legions and fought in gladiatorial arenas thousands of years ago.
  • Near-Extinction: After World War II, only about 14 Mastiffs remained in all of England. American and Canadian imports saved the breed.
  • Drool Champions: English Mastiffs are legendary droolers—keeping towels handy is a lifestyle requirement.

Breed History

The English Mastiff is one of the oldest and most ancient dog breeds, with depictions dating back to 2500 BC in Assyrian art. Mastiff-type dogs were used in ancient warfare, gladiatorial combat, and as guard dogs throughout European history. The breed came to England with Roman invaders and was later used for bear and bull baiting, guarding estates, and as war dogs. The modern English Mastiff was refined in the 19th century. After World War II, the breed was nearly extinct in England and was revived using dogs imported from the United States and Canada.

Personality and Behaviour

  • Gentle Giant: The modern Mastiff is remarkably gentle and calm. Despite their imposing size, they are one of the gentlest giant breeds.
  • Loyal & Protective: They are deeply devoted to their families and are naturally protective. Their size alone is an effective deterrent.
  • Calm & Dignified: They carry themselves with a quiet dignity and are not excitable or hyperactive. They prefer a calm, relaxed lifestyle.
  • Good with Children: Well-socialized Mastiffs are patient, gentle, and tolerant with children—though their size requires supervision.

Care

  • Exercise: About 20 to 30 minutes of moderate daily exercise. Short walks and gentle play are sufficient. Avoid intense exercise, especially during their prolonged growth phase.
  • Grooming: Their short coat needs only weekly brushing. They drool extensively—keep towels available. Clean facial wrinkles daily to prevent infections.
  • Diet: Feed a high-quality giant-breed food. Large-breed puppy formulas are essential during their slow, prolonged growth. Controlled portions and slow, steady growth prevent joint problems.
  • Health: Watch for hip and elbow dysplasia, bloat (life-threatening), heart disease, cancer, eye conditions, and cystinuria. Their shorter lifespan is typical of giant breeds. Regular vet checkups are essential.

Frequently Asked Questions About Mastiff

When you talk to a breeder, you're not just asking “do you have available Mastiff puppies?” You're looking for a match in the process of rehoming a dog. As a prospective dog owner, you are assessing how predictable the dog's health, temperament, and long-term welfare will be and whether the breeder's practices reduce avoidable risk.

You should engage in a conversation about the following topics:

  • Which health tests and genetic screening do you do specifically for Mastiff, and can I see the results?
  • What do you do if a puppy develops a serious genetic condition? What contract, policies and support do you offer as a breeder?
  • How are puppies raised from birth to 8+ weeks? Ask about socialization, philosophies on early neurological development, handling, and exposure.

The real cost of a dog isn't just the puppy price. After year one, the cost of a dog includes the predictable annual costs + the unpredictable “risk costs.” Your goal is to make the cost legible before you commit, as one of the top causes of surrendering a dog is not being able to afford the dog in later years.

To help you assess these costs, Paction has created the Ultimate Cost Calculator. You can also read an article written by a Paction breeder on why a prospective dog owner should focus on the ongoing costs of dog ownership and not “how much” the puppy costs.

Every dog breed has certain health issues that tend to occur more often, but what matters most is how predictable and preventable those risks are. For many breeds, common concerns include inherited conditions (such as orthopedic, eye, or cardiac issues) as well as lifestyle-related challenges like weight management, dental health, skin or ear problems, and anxiety.

Responsible breeders help reduce inherited risk through appropriate health testing, careful selection of breeding pairs, and transparency about family history. To understand more about responsible breeding programs that prioritize health and genetic screening of breeding pairs, check out Making Science Simple: Canine Genetics for Puppy Shoppers.

As an owner, you play an equally important role. Consistent preventive veterinary care, proper exercise and enrichment, healthy nutrition, and early screening can significantly improve long-term health outcomes.

Whether a Mastiff is right for you depends less on the breed itself and more on how well its typical energy level, temperament, and care needs align with your daily life. Important factors include your schedule and activity level, living environment, household dynamics (such as children, other pets, or allergies), and tolerance for noise or independence. Long-term fit also comes down to maintenance like grooming, training needs, and how often you travel or rely on outside dog care.
