Dogs have incredible vision and can see the security features on our money. They can even see traces of accidents left on the floor. The U.S. Government has implemented various security measures on our currency to prevent counterfeiting. For example, bills have security threads and watermarks that can be seen under ultraviolet light. The $100 bills even have a holographic security ribbon. Dogs can easily spot these features without the need for ultraviolet light. They can see ultraviolet light, unlike humans, which helps them in various ways, such as identifying predators and following urine trails. If your dog is acting strangely or exhibiting certain behaviors like barking, stalking, or wagging its tail, it may be seeing something that you can’t.
Dogs and Ultraviolet Light
Dogs have had the ability to see ultraviolet light since ancient times, which helped them survive in the wild. Dogs have different eye structures than humans, allowing them to see ultraviolet light. Some trainers even use UV light to train dogs. Dogs can also detect urine or bacteria on surfaces without the need for a black light. If your dog keeps sniffing a certain area, it may need extra cleaning.
Dogs can see UV light and spot security features on money easily.
