The Dr. Sniff Sulfate-Free Dog Shampoo is great because I combined nature's best ingredients, such as organic coconut oil, argan oil and neem seed and leaf extract. This professional shampoo naturally cleanses, restores and fortifies your coat. All of this fancy talk simply means it cleanses naturally and makes you look, feel and smell amazing. Our hypoallergenic shampoo is safe for sensitive sidekicks on all types of hair and fur - Dr. Winston Sniff. Available in a 13.5 oz. bottle.
