My very sweet male Mastiff has suddenly started growling, and even snapped at a few people (without hurting them). We are worried he might hurt someone. He only does this to people he doesnt know, both at our home and out in public. Any help would be greatly appreicated. We bought a prong collar and immediately reprimand him when this occurs but we really want to stop it before it gets out of hand. We have always owned Rottwielers and have never experianced this before.

sudden aggression is a bad sign….
hopefully he is neutered,, and i suggest you get into a group obedience class,, more for the socialization purposes than anything else
