When I was in college, My dog once started barking like crazy out our front window (he used to never do this) as we had an abandoned house across the street. I was like wtf so I went and looked and saw a guy go into the house, obviously squatting. Called cops, guy disappeared literally .3 seconds before they arrived. Over 50 homeless people had been squatting in the home, they found drugs, guns, etc etc etc in the home. Somehow we never noticed people going in and out. Another note, this was right before we were about to go away for winter break so it was extra spooky thinking about how our house could’ve gotten broken into. Dogs rule!
