If you are looking at ways in which you can improve your security at home, you may consider getting a dog. A dog’s gruff bark can be enough to ward off criminals but you do need to think carefully about having a dog for this reason. If you want to have a proper security dog then it wouldn’t be able to be treated like a family pet. They need to have strict training and often not too much interaction with other people. If you have young children, this may not be the best idea.
Dogs have been used in security for a number of years and the police still use dogs as a big part of their investigations. Their dogs have to be trained from a very young age and are taught to listen to their handler.
There are many other ways in which you can protect your home such as with a cctv system, alarms and security doors / windows. Having a family let that barks when someone comes near or into the property is probably enough without having to go the whole hog and having a security dog guarding the front door
