I'm red hot mad!

Yesterday morning someone tossed chocolate cookies in my backyard. Fortunately, I always go out with the dogs when they are in the yard and I found them before they might have been eaten. I almost didn't see it until my GSD looked at it and then me. Like "Hey mom, why is this out here?"
People around us know we have a GSD, an elderly pug and a rottweiler puppy and they can't do anything bad around us because my GSD will go on alert and the pug barks. It just honks me off so bad. My dogs aren't outside alone day and night, they don't bark their heads off and they don't run loose. Who ever did this was up to no good.
The story gets even better when I was walking the dogs an hour later and found a large knife near my house. I called the cops to come and get it but it freaked me out a little bit. Thank god I am vigilant about my dogs and I have a big smart furry protector.
