It just isnt right. Melissa Chaining encourages aggressiveness. When the chain is all there is, any animal, child or adult can enter at any time. I'd bite anything inside my little circle, myself. They twist and make the chain shorter.
Chains are a bad idea for the long haul.
They may be used for emergencies but never for primary containment. There times when we have no choice but to tie our animals out for short periods of time. I am constantly aware of what my big boy is doing, he is my crafter critter. I fly out side to find my beloved Zaz in a frenzied fit, screaming at the top of his lungs, thrashing wildly and biting at his rear leg and anyone close by. Zaz is a very large animal, and a very strong young animal.
