    Batteries: 3 AA (not included)

    The Vansky UV Flashlight Blacklight reveals more than just dog urine stains; it also reveals food stains on carpet and furniture, and it detects scorpions. It has 51 LED lights that will last up to 15 years, and it only takes three AA batteries (not included). The compact design is easy to carry and will fit in your pocket, and it can detect fake currency.

    It is made of aluminum alloy, and the run time is 4 to 6 hours with full batteries. The nanometers run from 390 to 395, making it perfect for detecting dog urine stains, and it comes with a 1-year warranty.

    It does not detect cat urine, so if you have a kitty, look for a UV light with a nanometer from 365 to 385 for cat urine detection.

    This UV light will pick up dried stains. Keep in mind that if the stain is still fresh and wet, the UV light will not pick it up. This light will also pick up everything, so it may be hard to differentiate dog urine from something else. Nonetheless, whatever it picks up, you’ll be able to clean, making it our overall best blacklight for dog urine stains, especially for the price.

    Pros
    • 51 LED lights
    • Lasts up to 15 years
    • Compact design
    • 1-year warranty
    • Reasonably priced
    Cons

    It does come with batteries, but they may arrive dead. It also has only 9 LED lights, making it harder to detect stains from a distance. However, for the reasonable price and small, compact design, this light is our pick for the best blacklight for dog urine for the money.

    This light is strong enough for professional use, and it works well outdoors, too. It’s not as lightweight as the other lights on our list, but it does a good job illuminating stains. It requires 6 AA batteries, and the batteries often need replacing, which is a downside.

    This light will do everything other UV lights will do, but it does not contain as many LED bulbs as others on our list.  You’ll also need to make the room as dark as you can in order to see any stains. However, it works well for what you need it to do for the price.

If you’re only looking for a UV for that specific purpose, this small rechargeable light may just be the ticket.

    This UV flashlight light is lightweight and easily fits into your pocket or a backpack. This light also has a zoom in/out feature that allows you to widen or shorten the light range. For being so small, it’s surprisingly strong, durable, and made from aluminum alloy.

    Size

    You’ll want to consider if you want a small, compact UV light or a bigger, more professional UV light. If you’re looking to buy a UV light just for dog urine stain detection, the small lights will work just fine.

    Bulbs

    When it comes to LED bulbs, the rule of thumb is the more, the better. If you want super bright, go with at least 51 LED bulbs or higher.

    Protect Your Eyes

    You don’t have to wear safety glasses while using UV flashlights; however, it’s important not to shine the lights directly into your eyes or someone else’s eyes because it could cause eye damage.

    Wavelength

    When looking for dog urine stains, you’ll want to go with a nanometer range of 385 nm to 395 nm. However, if you have a cat, this range will not work for finding cat urine. If you have a cat, you’ll want to stick with 365 nm to 385 nanometers.
