CasPer was rescued at the side of the road. I believed he got lost from mum or he lost his way home. Casper loves to play his pit pit soft toy or a small size empty mineral water bottle. He is a very alert puppy and will bark when he hear strange noises coming from the door. He is not suitable for family who can't spend time with him as he dislike being cage. You may use a fence but not a cage. If you can give Casper a home, please call me at. A lot had called asked the same question if he is a Chihuahua...My answer is I DON'T KNOW..COS I RESCUED HER AND HAVE NOT SEEN HIS MUM.
