More details about the Mastiff

Mastiff: Origins and history

In 55 BC, when Caesar’s legions invaded the British isles, they came face to face with two types of dogs: the first was stocky, with a disproportionately big head, and a short yet powerful jaw- of which the poor legionnaires’ calves soon became thoroughly convinced. This dog was highly likely the Bulldog’s ancestor, and had some of the modern-day Bullmastiff in him. The second dog was of exceptional dimensions, more of a lion than a dog in fact! He was the direct descendant of the assyro-babylonian mastiffs, imported to England by the Phoenicians some 500 years prior to the Roman invasion. He made the Epirus Molossians- whom the Romans considered to be excellent warriors- look like helpless little companion pups. As a result, upon conquering Britain, the Romans brought back these impressive English dogs with them, dubbed them ‘Pugnaces Britanniae’ (or ‘British Pugnaces’), and used them in arena fights with the most ferocious of animals. The Mastiff is a direct descendant of the latter dogs.

Training a Mastiff

This Mastiff is not the most docile of his category but will nevertheless be receptive to training if it is firm, coherent and respectful of the principles of positive training. 

This mighty molossian will not tolerate any form of brutality at the hands of his master and will be much more inclined to cooperate if it is those good behaviours that will be compensated and reinforced.  

At times unaware of the extent of his strength, the training will have to prioritise leash-led walking, pull-free, so that when the dog becomes an adult, walking him will be a breezy, pleasant affair! 

At any rate, with a dog of such proportions, it is advised to call on a professional dog trainer who will accompany the owners in the training process.

Mastiff: Purchase price

The price of a Mastiff varies depending on its origin, its age, and its gender. You have to estimate an average of between £700 and £1120 for a dog that is part of the Kennel Club. 

Regarding the monthly budget, it is quite significant since you must set aside around £80 per month to be able to cater to this giant’s needs.
