Great deal on a gallon of shampoo!! It’s whitening, and it did a great job on our palomino paint after a pretty muddy winter & spring. I was pleased, and you don’t need much in your bucket! Wasn’t sure how it would handle a horse since it’s supposed for dogs. It works great and won’t discolor colored hair. I used it on my black and tan GSD and my red Merle Aussie/Golden Lab. Smells great, nice lather, easy rinsing!! HIGHLY RECOMMEND. – Chewy.com Mr. Groom Customer Review
