As it turns out, dogs can actually be fascinated by Christmas lights, just like humans! Many dogs love to watch the colorful lights and can become quite interested in them. However, it's important to note that some dogs can be sensitive to bright lights or sudden flashes, so it's important to supervise them and make sure they don't stare too long or get too close to the lights. It's also a good idea to keep an eye out for any signs of stress or anxiety, like panting or pacing, and take steps to help your dog feel comfortable and safe.
