Hi, I am thinking about getting a Doberman as a guard dog for my home. I live in a city where there have been a few burglaries in my neighborhood recently, and I want to make sure my home is safe. I have heard that Dobermans are protective of their owners and territory, but I am not sure how they react to intruders. Do they become aggressive or just bark? Will they attack if they sense danger? I don't want a dog that will harm someone, but I also want one that will deter any potential intruders. Can someone with experience with Dobermans provide some insight into how they react to intruders? Thank you!
