Prevent your pup from revisiting the same spots with Nature’s Miracle Advanced Platinum No More Marking. This indoor training aid is specially formulated to discourage destructive marking behavior. The repellent scent deters your dog from returning to the treated area. Plus, it’s safe for use around your pets and home when used as directed. Before using, clean the area with a Nature's Miracle Stain and Odor Product (sold separately). Then saturate the target area daily and praise your dog for positive behavior. Repeat as needed until your pal’s bad habit is broken. When cute pets make not-so-cute messes, Nature’s Miracle is here to help.
