I let the dogs out every evening to run and play and exercise. We live on an island so they can run in the woods and I don't have to worry about them wandering off. We built the kennels next to a 10 acre pond so I just wash the pens in the pond. I formed concrete slab with a
3 1/2 inch pitch so it dries in minutes of washing them down. It takes me about 5 minutes to wash 3 slabs down and feed and water .
It use to take 20 minutes to wash slabs when I was feeding Diamond. Dogs looked great on it but it was a bittch to wash down the slabs.
Switched feed and now it only takes about 5 minutes to wash all kennels spotless.
