This gentle shampoo contains fragrant d-Limonene, the natural oil rendered from orange peels. Pet professionals recognize d-Limonene as an effective deodorizer, degreaser, and fur stain remover which helps to calm & relieve common skin and itching problems associated with flea bites and other dermatitis. In addition to thoroughly cleaning your pet, the concentrated citrus oil in this quality shampoo will bring out the coat’s natural highlights and generate a brilliant sheen. Safe for dogs over 6 weeks old. Do not use on cats (a small percent may be allergic).
