Anyone seen a loose dog?

We live on the corner of Milburnie and Donnelly....has anyone seen a loose dog in the area? For the past 2 days in a row we have found what looks like dog poop in front of our house and it is definitely not our dog's. Today, it wasn't there in the morning, and I just took our dog out and it was there, fresh. It's very close to our front door, so its not someone walking their dog (unless they're walking up in our yard!)
