My dog Teddy is a nervous sort who would have a stroke if his leash started blinking, but this would work for other, calmer dogs. You probably take a flashlight when you take your dog out for nighttime walks, and that helps motorists, bicyclists, and other pedestrians see you. If you don’t keep your dog on a tight leash, they may not see your companion. The NightSafe Flashing Dog Leash from Gadgets and Gears has blue LEDs (and reflective tape to make the lights more visible) that can blink or stay on to clearly show where your dog is. The 47″ leash is made of reinforced nylon and is powered by 2 R2032 button cells that can provide 50 hours of continuous lighting. The leash is visible up to 100 yards. The NightSafe Flashing Dog Leash is $34.95.
