The English Mastiff
boasts a large body, broad skull and square head, and is the largest dog breed when it comes to mass. They are not as tall as the Great Dane
or Irish Wolfhound
, but are more robust. The coat colors are described differently by kennel clubs, but are mostly fawn or black brindle, blue brindle and black. A black mask should be present in all cases.
The coat is short and smooth. It is easily maintained through brushing and wiping to bring out its natural luster. The English Mastiff sheds on average.
The English Mastiff breed is a versatile working breed, used to pull carts and carry heavy loads. They are excellent guard dogs to homes and children. They can be kept indoors so long as they are sufficiently exercised. Going for a daily walk is recommended, or simply letting them loose in the yard. They are inherently lazy, but walking is instinct to them and is good for mental and physical health.
The average lifespan of the English Mastiff is 10 to 12 years.
The English Mastiff is powerful and muscular. They are very gentle creatures, a stark contrast to its imposing appearance. They are natural-born guard dogs, though they rarely bark. They defend people they consider family, as well as grounds they deem to be part of their territory. Regardless of how friendly and docile they appear to be, at the first sign of danger it is instinct for them to protect, unless they are told to do otherwise. They are watchful and patient, perfect for children. They respond to firm and gentle trainers, and love to please. Socializing them early on will prevent any aggression towards strangers.
Romans called the English Mastiff “Pugnaces Britanniae.” The origin of term “Mastiff” is still unknown, but many say that it was evolved from the word “masty” meaning “powerful”. In the medieval times, this breed was used in brutal blood sports such as bull-baiting, lion-bating and dog fighting. In 1415, Sir Peers Legh was injured during the Battle of Agincourt, and his Mastiff dutifully protected him throughout the rest of the battle. They both survived and that dog serves as the foundation of the Lyme Hall Mastiffs. This pedigree was a key element to the formation of the modern Mastiff breed.
It is said that the Mastiff was interbred with other giant breeds like the St. Bernards and Bullmastiffs. It is ranked as the 28th most popular breed in the USA.
This breed demands for proper diet and regular exercise. Excessive running could be detrimental to the dog for the first two years of its life. However, they must get used to exercising otherwise their laziness could lead to serious health problems such as obesity, cystinuria and osteosarcoma. Hip dysplasia is another common problem due to the breed’s large size. Other health concerns include cardiomyopathy, vaginal hyperplasia, hypothyroidism and progressive retinal atrophy.
