There is a larger solid black dog with a bright red collar that has been running loose on Loop Rd near Riverwood Golf at least since the middle of the week. I believe it is a male, since he cocks his leg on the trees in my front yard. He's probably 50-60lbs or so. He keeps coming back to our yard, I am guessing because of our own dogs, who don't appreciate the visitor. If anyone knows who he belongs to, give them a heads up, because I will have to call animal control in the very near future if he keeps hanging around. Have not been able to get a pic, because every time he sees a person, he takes off.
