How can I ensure that my dog is comfortable and safe at night by leaving the light on for them?

Leaving a light on for your dog at night can help them feel more comfortable and secure. Make sure the light is not too bright or too dim, as dogs prefer a soft, ambient light. Also, consider using a night light or a low-wattage lamp to avoid disturbing your dog's sleep. It's important to create a cozy and safe environment for your dog to rest peacefully throughout the night.
