Murphy’s Law clearly states that your dog will run off at the most inopportune time—and when he’s far away, or it’s windy out, good ol’ Bridger can’t hear you calling. Throw in the cloak of darkness and you’ve got a seriously misplaced pup—and a worried, late-for-the-party master. NiteIze has addressed this issue with their new PetLit, a clip-on mini-light that allows you to spot your dog from afar—and thus get him back home safe. A quick twist turns the bright, water-resistant LED on or off, and the lights come in two different designs. The PetLit is also a great way to keep tabs on an insubordinate canine that likes to meander just out of sight. $4.50; niteize.com.
