Mastiff lab mix facts

The Lab Mastiff Mix is a giant hybrid that results from combining a Labrador Retriever and an English Mastiff. Like most other breeds, its exact origin is not well-defined. It is unclear whether the mixed breed was intentionally combined together or if the original Lab Mastiff Mix was made by accident. However, it’s widely believed that this crossbreed has originated in the United States.

Meet the parents! The Labrador Retriever has its roots in Newfoundland, now a part of Canada. Fishermen preferred this breed as they would provide great help in tugging nets and towing carts filled with fish. The original Labradors were smaller than the ones we have today. They were bred with larger hunting dogs which gave birth to the modern day Labs.

The other parent, the English Mastiff, has an extensive history. They were believed to exist as early as the sixth century BC where they were used as war dogs and patrols. It was in the 18th century when dog fighting was ceased that resulted in their drastic transformation from being fighters to companions.

Combining these two you get a hybrid having which is as affectionate and brave as the Mastiff and as active and outgoing like the Labrador.
