Oh the mud and dogs and inside. I don't have labs but mini dachshunds [low to the ground and bring in everything on their bellies and feet.] still nothing like a labs that are huge yellow and furry. Do you stand at the back door with a towel. I do.
At the end of the day any feed left over goes in one feeder which I promptly cover with water to make duck soup. Minus the duck and my ducks slurp it up like it's the best thing going.
