This gentle shampoo contains orange oil, which has long been recognized as an effective deodorizer, degreaser, and fur stain remover. In addition to thoroughly cleaning your “dirty dog,” this shampoo will bring out the sheen and natural highlights of their coat. Orange oil is known to calm and relieve common skin and itching problems associated with flea bites. Will not wash off topical flea applications. Safe for dogs over 6 weeks old. Do not use on cats (a small percent may be allergic).
