yup,I have remembered that that is a stray dog.
Well,eventually this stray dog decided to be left alone,he left the Man,but the Man asked him to follow him with all possible humane persuasions,but the dog's final decision and conscience remained to be intact,the Man got a little annoyed that the dog wasn't following his self-centered desire,still,in the end the dog was Free ! Free from all confinement,the dog will face the dirtiness of the world and to be dirted that will be marked with great past experiences and wisdom ! Hurray for this stray dog ! Good luck,buddy :D
