"May I always be the kind of person my dog thinks I am"




What the Lion is to the Cat
the Mastiff is to the Dog,
the noblest of the family; 
he stands alone,
and all the others sink before him.
His courage does not exceed his temper and generosity,
and in attachment he equals the kindest of his race.
- Cynographia Britannica 1800

The Mastiff is an ancient breed and is believed to descend from dogs brought to Britain by Mediterranean traders in the 6th century BC. He is often called the Old English Mastiff. 

Mentioned in Persian and Roman literature, the Mastiff can also be found in Egyptian monuments. 

Originally bred to hunt the wolf, the Mastiff was also used to fight lion and bear in various blood sports. 

Once used as fighting dogs and dogs of war, today the Mastiff is primarily a guardian and family pet.

A massive dog, the Mastiff stands 30 inches at the shoulder and is the picture of dignity and strength. Grooming is minimal as the coat is short and dense. The Mastiff's coat comes in all shades of apricot, silver fawn, or dark fawn-brindle. His muzzle, nose, and ears are black.

The Mastiff is a compact and powerful dog. His fearsome appearance hides a gentle, loving family dog who prefers to remain around his home rather than roam. Loyal and alert, he makes a wonderful watch and guard dog as he is very protective of his family. He needs an owner who is strong, confident, and patient, and he should be put in obedience training and socialized early on. He does best with consistent, and firm but gentle training.

Due to his size, the Mastiff does best when living in a larger home with a good amount of fenced property attached. He needs regular exercise to keep his muscles toned.
