If it had been GA the livestock owner would have opened up on the dogs with a shotgun and it would have been over pretty quick.
Ex-Ochlocknee Ga boy has seen it several times. Wildlife authorities are trouble, not help. Wild dogs attacked in broad daylight once and I killed 5. They ran towards my brothers land and then I heard 5 more shots. The rest stayed away for months; the intense noise and howling put some fear into the wild dogs. Even if an ewe gets a minor bite on the head or neck, it dies of dog bite infection.
