Amazing transformation of a dog that has been abandoned by its owner

An urgent call for help on a lean dog was found stuck in a remote location. He could not be seen from the road, but fortunately he was found by someone who cleaned the area regularly. We do not know how long it must be stuck there, but from the desperate look in his eyes and the terrible form in which he was, we knew he had to be there some time. He looked like he was ready to give up but of course we would not let him do it! He was very tired, hungry and thirsty ... he was dried and had a bad wound with worms. We knew we would need to find him as well as possible so that he could have a good chance of recovery.
