Doggy was abandoned in October 2008 and was emaciated and weak. A lady named Noh and Betty helped care for Doggy until he was back in shape and healthy.
His previous owner dumped him because Doggy bit him. Perhaps his previous owner was a guy who abused him.
His new owner managed to tame Doggy but due to abandonement issues, Doggy is barking constantly whenever his owner is not in view.
So he urgently needs a new home with an owner who has the time and patient neighbours to train him so that he'll get used to being alone for a short time when the owner is not around or not in sight.
