Fear and Protective Instincts

[Kristin]

My dog is a two year old female pitbull mix. I had to put her companion to sleep a couple months ago, and we both mourned deeply and have since made peace. However, Bella looked to her companion for cues to respond to most situations. I've worked on socializing her by herself. She's doing much better out in public, but she is very protective of our home. I live alone, and am in college (pre-vet actually) and spend the majority of my time studying, not socializing, so she's not used to much company. When I DO have someone over, she is obviously scared and upset, and I have to keep her isolated for fear she'll bite (she gets incredibly upset if someone goes toward her or makes a move to touch me). Is there any way to let her stay protective of her territory but let her know company is not an appropriate target? I don't want to confuse her, and I hate excluding her or having her frightened. Any tips on how to handle this without someone getting bit would be greatly appreciated!

You are a wonderful observer of your dog's behavior which will enhance your performance as a vet. Since this is a complex behavior problem with big consequences for the dog, I urge you to consult with a behaviorist. Not only will that help your dog but you can gain experience that will come in handy when you are working with clients
