Kellar, a three-year-old English Springer Spaniel, loves to play fetch. It hardly seems to matter that he’s totally blind.
Kellar was originally trained to play ball with the commands “hot” and “cold,” according to his owners. They later added “warmer”, “passed it”, “left” and “right” to his vocabulary. The words, along with the sound of the flying ball itself, are enough to help him fetch almost as quickly as any other dog.
