While many collars and leashes have lights that flash, flashing lights can irritate some dogs and can sometimes trigger epileptic attacks in people. That’s why the Glowdoggie Leuchtie LED Safety Collar, used by search-and-rescue K-9 units in Austria, Germany, and Switzerland, doesn’t even have a flashing capability, as do many of the products listed here. The waterproof collar has also been used for the Iditarod Trail Sled Dog Race in Alaska, and it will soon be used by the Jefferson County Search Dog Association in Kentucky. It operates on two AAA batteries, has a LED life of about 17 years, and comes with customer support and a two-year warranty. Sizes range from 14 to 23 inches. and color choices include red, green, and blue, for $52.99.
