The Rogers County Sheriff's Department says the death of Jetta the dog, does not appear to be from abuse.
Rogers County Sheriff's Department spokesman Jerry Smittle says a man, whose name has not been released, came forward and told authorities his side of the story.
Smittle says the man told deputies he found a dog seriously injured from an apparent motor vehicle accident near his Winganon, Okla. property.
The man said he tried to help, but the animal snapped at him. Investigators say the man then explained he did what he thought was best, choosing to shoot the wounded dog.
Smittle says the man admitted to moving its body into a ditch away from his home, but refuted earlier reports he tied up and dragged the animal with his vehicle.
Rogers County authorities made the announcement of the man's confession Tuesday. No arrest was made.
On Saturday, Jetta was found lying on the ground about a mile from her home. Rogers County deputies initially said the animal was dragged to death behind a vehicle after her legs were bound together with steel baling wire.
The dog's death sparked a social media outcry, even gaining the attention of former University of Oklahoma and Dallas Cowboy head coach Barry Switzer. Switzer doubled the reward pledged by followers of Wild Heart Ranch's Facebook page , the Humane Society of United States of Oklahoma and the Oklahoma Alliance for animals.
