“French Mastiff is also known as the Dogue de Bordeaux. they’re miscellaneous dogs and can be used for anything (ie. working, herding, companion, guarding, sporting, non-sporting, etc. etc). either gender can be up to 27 inches at the withers and can weigh up to 100 lbs. although the Dogue de Bordeaux has a forbidding look, the dogs desire for attention and affection is intense! it’s somewhat leery of strangers and may be aggressive toward strange dogs, but it gets along well with children and makes a loving family pet with a calm, tranquil disposition. the Dogue de Bordeaux’s origin is not known, but it’s likely that the Mastiff and Bulldog each played a part in its development. the breed was once used as a fighting dog, challenging bulls, bears and other dogs. the Dogue is powerful and massive, but surprisingly athletic and quick. a large, expressive head characterizes this breed, and as with most dogs that were once bred for fighting, the Dogue de Bordeaux has a powerful jaw. this breed is built low to the ground, but is well balanced.”
English Mastiffs must be bigger, one of the EM’s next door weighs 200 lbs the other one 175.
