Chris Christensen Spectrum One Coarse and Rough Coat Shampoo delivers unsurpassed visible results, restoring a crisp spring to the coat. Hard coated terrier jackets will lay flat with great texture and furnishings will be fuller with more volume. Other breeds such as poodles, bichon frisee, bedlington terriers and double-coated breeds that are too soft and limp will have more substance for easy scissoring.
