This blind dog cane is a ring with a belt developed for dogs (and cats) that have lost their sight, to prevent injury. By attaching a circular vinyl ring around the dog's (or cat's) face, the dog will notice obstacles before they come into contact with its body, thus preventing injury. A special lightweight metal is used for the ring core, allowing it to be freely deformed. Please provide your dog's breed, weight, and dimensions (A: chest circumference, B: arm circumference) before purchasing. We may not be able to provide the product if stock runs out. The color of the fabric may vary.
