The Mountain Mastiff is a cross between a purebred Mastiff and a purebred Bernese Mountain dog. They are called hybrid dogs due to their origination from two different pure breeds.
The Mountain Mastiff dogs are large in size with an average height of 28 to 38 inches and weight in the region of 150 to 200 pounds or more. They are large dogs that are primarily used as guard dogs but they have temperament and characteristics that make them very loveable family pets.
These dogs are calm, gentle, affectionate and extremely loyal to their family. They are alert and protective dogs that make excellent guard dogs.
