Things You'll Need
- Black light
- Paper flags on toothpicks
- Urine odor-neutralizing agent such as Clear the Air in granule form
Instructions
Use a black light at night to find the urine spots that are causing the odor.
Place flags in urine spots so you can find them in the daylight the next day to complete the next step.
Apply urine odor-neutralizing granules to the spots. Only a capful of granules, at the most, is needed. When the dog needs to go out, take him to a different spot in the yard to give the granules a chance to take effect.
Remove the flags, and repeat as necessary once a week.
