When any dog, especially big ones I've had or fostered, shows even unintended aggressive behavior, I go into a month of the Nothing In Life Is Free training mode & it is funny how quickly things fall right back into place. It works magic with a dog after he's forgotten his role in our "pack" or family. Big, powerful dogs who decide to even momentary be alpha can be dangerous & hurt somebody or another animal so it is helpful to get right on reminding them who really is the leader in this family.
