Review on GearLight XR98 UV Black Light Flashlight - Powerful 100 LED Blacklight Flashlights for Pet Stain Detection, Scorpions, and Bed Bugs - Works with Carpet Odor Eliminator by Erica Williams

Well hidden say in the corner or pee on the couch or chairs in the kitchen or anywhere else. DO NOT BUY THIS ITEM, IT WILL NOT show you the pee spots. General . I literally sat and watched my dog pee on my rug (yes he got yelled at and got in trouble for it) and he DID NOT APPEAR (he wasn't glowing green or whatever he's touting) WHEN I SHOWED THIS HANDLE BY THE LIGHT IT IS ON. So no, it won't help you answer the question of whether your dog is peeing on things in your house if you're not looking because urine stains won't appear.
