Coco was blinded by retinal degeneration and cataract in the right eye. The left eye had been removed surgically due to painfully high pressures inside the eye called glaucoma. Yet visitors to his house spend hours playing with him before realizing he no longer has vision.
His family will call out the name of a specific toy and Coco will find it in a box stuffed with dozens of toys. They launch the toy down a long hallway so that he can zoom after it, skidding and sliding at top speed to fetch it. His favorite is the ball with the bell but the soft, fuzzy stuffed animals are a close second.
If anyone ever doubts whether blind dogs live joyful lives, Coco can help them see the truth clearly.
