Retrieve Ear Wash is a gentle, yet effective formula that consists of all-natural active ingredients. It's designed to help dissolve earwax and remove foreign debris from your dog's ear canals, resulting in improved hearing, balance, and quality of life. Contains witch hazel and tea tree oil which act as natural disinfectants and have been known to work for certain antibiotic-resistant ear problems. Echinacea extract is also added to reduce the rate of infection and duration of intensity of symptoms. Can be used as often as needed and is especially recommended after bathing or swimming. 4 fl. oz.
