Bio-Groom Ultra-Black Dog Shampoo – Color Enhancing Pet Shampoo, Dog Bathing Supplies, Puppy Wash, Dog Grooming Supplies, Cruelty-Free, Made in USA, Coat Brightener Shampoo – 12 fl oz 1-Pack

Used on my black standard Schnauzer. Best shampoo I found for her. She is shiny, soft, and the wonderful smell has lasted for days so far.

Does the job, but just not a fan of the smell personally on my dog.

Bit on the expensive side..but its a great shampoo for dogs.. have been using this regularly for the past one year for our doberman pup - and the shampoo cleans well, makes his coat lustrous. It has an artificial black coloring i suppose - but it has not harmed my dogs coat/skin.. For healthy coat, nothing beats proper brushing every day - I use the kong zoom groom brush for that. We give him bath every fortnight..

Honestly I never realized the benefits of using a special shampoo for black dogs but after one bath I saw why. My dog's coat was no longer dull. Her coat shined and was so smooth. It reduced her shedding significantly and she smelled great. I will never go back to any other shampoo for her.

Didn’t like how product felt on the pups hair, kind of heavy and toughening. The hair didn’t look any better later and felt dull. Did I use it incorrectly? Not a top performer.
