This happened to me, so I know how she/ they felt. I was cutting grass one day s a couple of summers ago, I was 16 at the time I believe. I had just come back inside from cutting the grass, using the back door. I hopped in the shower, as I had plans later that night. Well, half way through my shower, my dog came upstairs and started scratching on the door. This IMMEDIATELY made me know for a fact something was wrong. As she literally NEVER came upstairs. So I hopped out of the shower quick, fast, and in a hurry, and looked down my stairs. And there was the BG, a black guy walking in front of the bottom of the stairs. So I grabbed my dads 12 G and called the police. Long story short, he left, they arrived, and of course, never found him or anything. You feel VERY vulnerable, and everyone who isn't a family member wants to kill you. Just a heads up, a dog will ALWAYS be in my house from now on. I also have an alarm system that beeps anytime anyone opens a door or window. And let's just say that if a BG gets in my house, then the pitbull is the least of his problems. The alarm system isn't as good as the dog. But hey, why not have both?
