The Muscle Mastiff is a cross between a purebred Mastiff and a purebred Dogue de Bordeaux (French Bulldog). They are called hybrids due to their origination from two different pure breeds.
These dogs are large in size with an average height of 28 to 37 inches and weight in between 100 to 200 pounds or more. Despite their large size and imposing personality, these dogs are calm and gentle natured. They are suitable for families with children and will not create a problem with other dogs and pets in the family if the later are well behaved too!
These dogs are loyal and devoted to their family. They are found in different colours and make good watch/guard dogs.
