Sounds like a sweet idea—dogs do have a natural protectiveness that can be super helpful. Just make sure you start with the basics: temperament check, obedience training, and plenty of socialization so they don’t get overexcited or skittish. Train them to be calm around strangers, not aggressive, and always keep an eye on the legal side—local ordinances and liability can be tricky. A good routine, clear signals, and a happy dog will make the neighborhood safer and keep the pups happy too. Keep it fun, and don’t forget to give them lots of treats for a job well done!
