If you're worried about break-ins at home, this could help . . . A former burglar claims the best way to prevent them is also one of the cheapest: Just put up a sign that says "BEWARE OF DOG."
Most burglars will move on and try another house.
He says it's more of a deterrent than those signs that say you've got a security system installed. And they only cost about five bucks on Amazon.
There might be a few drawbacks, though. For example, they're not exactly aesthetically appealing. So your neighbors might not like it.
Also, someone on a Reddit thread said they put one up at their new place. Then friends kept calling from outside the first time they came to visit. They knew he didn't have a dog, and thought they had the wrong address.
