Lacey does growl at well, everything. She is very vocal and is always making some kind of noise so in our situation we're not too concerned about it. She does get protective of her chewbones but will let Mandy take it but she doesn't want the cats near it. I guess you should try to teach Major not to do that. Maybe offer him a treat to let you take the bone away and then give it back to him. Let him know it's ok for you to take things from him. Maybe someone else could give you more advice on training him to do that.
