The Illinois law for dog tethering needs changed to further protect the dogs from harm. It needs to be changed to state that: No person shall chain, tether, fasten, tie, or restrain a dog to a tree, house, fence, or any other stationary object. The dog shall be on a leash & supervised, or in a fenced yard.  Help end animal neglect and cruelty by changing the Illinois tethering law. 

Tethering can cause:

severe behavioral issues

endangers the dog & puts it at risk of heat stroke or hypothermia

unable to flee if a dangerous dog approaches it,

unwanted litters, 

risk of breaking the tether and getting tangled and fleeing
