Although it could be difficult to manage as a single owner, getting a dog can deter potential burglars and they can guard your home when you’re at work or out. You don’t have to get an aggressive dog, just one that will bark if strangers approach your property. Your dog will not only be a companion, it’s an alarm that can’t easily be turned off. If you can commit to having a pet dog and have the living space to take care of one, you may feel more secure as a defence against a break in.
