While I'd agree that an aggressive, barking dog isn't desirable in most cases in the western world, I think that perhaps Archowells is from an area where things are very different? Please correct me if I'm wrong! I had a friend work in Ghana for a time (different country, I know!) and in the area she stayed, dogs were genuinely the most accessible and effective security systems available. Even in the housing her company put her up in.
If you have other options,
@Archowells, I do encourage you to consider them. Dogs just aren't as effective as a good security system that authorities reliably respond to, which is one of the reasons I wouldn't recommend them to anyone who has that option. If not, it may be that this puppy isn't the right temperament for the job you need her to do. I urge you not to try to change that by hurting or scaring her in any way - a scared dog is going to be less likely to protect its space than a confident dog with an attachment to its owner and territory. She is very young and may still find her voice, and you can encourage her by praise, attention, and food when she does bark. Or you may find that a different dog will be better at the job, maybe an older one proven to bark as Storyist suggested, especially if your need is urgent.
