It works!
"Used regular Mane and Tail for my horses and Boxers for years but decided to try this formula for my pups and it's great. Has a nice smell, whitens flash (white areas) and leaves their brindle coat soft with a nice sheen. Very good deodorizer without heavy scent. Most shampoos fade within a day or two this lasted 5 days. Probably would have lasted longer if my Boxers didn't love running out in the rain (live in FL where it's raining every day now). Even then didn't have that overwhelming wet dog smell."
