Say hello to Tucker, a rescue pup with a smile that makes him look more like a bat than a pooch! This 3-year-old albino Chihuahua-miniature Pinscher suffers from a disease known as MPS VI (mucopolysaccharidoses). The illness causes deformities and a host of medical problems. This means the doggie is not able to walk with his front legs, and has to wear protective goggles due to blurry eyesight. Yet, this pooch is an Instagram star and a real heart-stealer!
