French Mastiff Help!!!!?

a one year old male, depending on his parents, shoul dbe in the neighborhood of 125 lbs. if he was neutered young, he will not grow to his full potential. we don't recommend neutering until 18 months of age in order to allow the male to reach his full weight. Are you sure he is full DDB? Lack of wrinkles and a roman nose would indicate to me that he is mixed with something else.
