New dog chain-outs

I once saw a neat photo of the military dog housing in the snow. It was the same setup except a metal posy( 4" pipe) with a wood wine barrell on top. The 4 " pipe post had a solid metal ring around the bottom that was abou 6 or 7 inches with the chain connected to that so it could always move freely around the post and their water buckets hung up high on the side of the barrell like yours so they could never knock it over. I like the setup up because in a cleared area there is no end to the amount of chain or running space you could give a dog if there is nothing around for them to tangle in. Nice work!!
