Many people use chains, tethers, or tie-outs to have their dogs outside, yet restricted.
I see all of these devices advertised in popular dog magazines, I see them hanging in pet supply stores, and I see many dogs on the end of one of them. Unfortunately, I have never seen any one of these devices come with instructions or recommendations on how, why, and when it is appropriate to chain, tether, or tie-out your dog. Also, I have rarely seen any written information regarding chained or tethered dogs. I live in a rural neighborhood where some dogs live on chains twenty-four hours a day. On one particular day, my neighbor's dog came over for a visit, but was not his happy usual self when he arrived.
