Love the one of Gracie covered with dirt by the dust bathing hen!
I use dogs to help deter predators as well. But first and foremost I have made my coop Fort Knox. Nothing gets in there at night, there is not the tiniest opening. It's all solid walls and hardware cloth. I also use hot wire as an added measure and with excellent results. That also helps with any other roaming critter who decides to check things out and is really effective on stray dogs.
