Small dogs like pugs or chihuahuas are very active and they like to chase around like crazy! They are incredibly nimble and have perfect paw eye coordination. The small chihuahua in this video lost his sight, due to a cataract. But blindness was never going to stop him from being a happy and active dog.
The problem was of course that he kept bumping into things and kept hurting himself until his owner came up with an idea to make him a special harness, and it’s a wonderful invention. Pure genius. You have to see this.
