Rare Mastiff Dog Breeds




There are many types of Mastiffs. This list includes brief descriptions of some of the rare Mastiff dog breeds.


Fila Mastiff


Also called the Brazilian Mastiff, this breed was used as a guard dog, hunting companion and as a shepherd.

During a hunt, it was known for not damaging the prey, instead holding it for the hunter. They make excellent guard dogs, but it is absolutely imperative that they are properly trained and socialized when young.

They tend to be wary of strangers and failure to socialize when puppies can lead to aggressive behavior.

Colors include fawn, red and brindle. The coats are short and little grooming is required.
