Darrel, I think that Mastiff needs to lose a few ounces of testosterone producing things, if it hasn't already been neutered, you would be surprised how quickly that aggression will disappear. if it has already been neutered and it is still aggressive, then it should be put down before it seriously hurts a person especially a child. A large dog like that can easily kill a child, no mucking around. Glad you gave it back, Gigi wouldn't last too long with it around, dogs that fight are very bad news, and large dogs that fight are potential killers.

You did the right things giving it back. Start with a puppy, at least it is a product of your family surroundings not someone elses, dogs are like children, all about environmental conditioning.
