your dog is a companion, not a slave. you don't want it to be obedient, you want it to be empathetic. it will respond far better to affection than to discipline...
now, that dog, right there, is actually telling it's cohabitant that it doesn't want to go home at all. it wants to make the creek it's new home. as an independently thinking entity, it has every right to express that desire and should not be punished or disciplined for it. to the contrary, it's the dog's cohabitant that has the responsibility to convince the dog to come home - and leave it if it insists on staying.
a little walk towards the car would have brought the dog running....
