Content overview


The Mastador dog breed may have developed naturally over time, but designer breeders in North America began purposely mixing English Mastiffs with Labradors in the late 1990s. Breeders wanted to combine the two parent breeds to reduce the health risks associated with pure breed inbreeding and to make the ideal family companion dog. As the demand for mixed-breed puppies grew, they continued to breed Mastadors.

Let’s know about it’s parent breed

Labrador Retriever

The Labrador Retriever, originated in Newfoundland, Canada and is also known as the “St. John’s Dog,” “St. John’s Newfoundland,” or “Lesser Newfoundland”. These canines were recognised for their swimming prowess, work ethic, and friendly attitude.

Labrador Retriever dogs spent their days working alongside their masters, retrieving fish that had gotten away from hooks and towing lines, and returning home to spend the evening with the fishermen’s family. The Labrador retriever was originally recognised by the American Kennel Club in 1917.


The Mastiff is descended from the Molosser, one of the oldest canine breeds, which is said to have originated in Asia’s mountains, maybe in Tibet or northern India. Their ancestors can be seen in a variety of breeds, not just mastiffs. In those cold, high passes, they were most likely employed to protect flocks from predators.

Mastiff-type dogs were used as guard dogs, war dogs, and as entertainment against lions and other dangerous animals. The modern mastiff was developed in England. In 1885, the American Kennel Club recognised the breed.
