We propose a method for guiding dogs in an outdoor environment. By harnessing dogs' nature following light, we aim at guiding dogs outdoors with light from irradiation equipment attached to the dogs. First, we investigated which light can be used to guide dogs outdoors. We found that the suitable light is Spot-Light, which is condensed light of a high-brightness LED using a convex lens, special feature is the edge stand out. Subsequently, we investigated how much illuminance a dog can detect Spot-Light in a bright environment. We found that the illuminance difference between the ambient light (3500 lx) and Spot-Light (4500 lx) was only 1000 lx, a dog detected Spot-Light. Also, the higher the illuminance, the easier for a dog to detect Spot-Light. According to our experimental results, we developed a small irradiation equipment that can be mounted on a dog and can irradiate Spot-Light which dogs can detect in outdoor environment.
