Mastiff Breed History

The Mastiff, a majestic and ancient breed, has its roots in the distant past. Originating over 5,000 years ago in Asia and Africa, these gentle giants were primarily bred for power and strength.

They served as war dogs for powerful civilizations like the Egyptians, Greeks, Persians, and Romans. Often described as “gentle giants,” Mastiffs are known for their striking size and calm demeanor.

Throughout their history, roles included hunting large game such as bears or wolves. They served as guard dogs on English estates. Mastiff breeds participated in bloodsports like bull-baiting until these events were banned during the early 19th century.

In the early 1800s, British sportsmen took note of the impressive skills displayed by these dogs during a visit to Canada. They were so enamored by their intelligence and trainability that they imported the labrador retriever puppy back to England. Once on British soil, these dogs were selectively bred with local retrievers to create what we now know today as the purebred Labrador Retriever.
