The tether must be attached to a properly fitting collar or harness.
The use of training collars, choke chains, prong collars, slip collars
or any other type of collar which tightens as the dog pulls is prohibited
for the purpose of connection of a dog to a tether.
The tether must not allow a dog within five feet of any potentially
dangerous places or obstructions such as pools, walls, vehicles, roadways,
trees or any other objects upon which an animal could harm itself.
