My chocolate lab got mange. We cured in two weeks. Once daily we slathered her head to toe in a mixture of coconut oil, neem oil and tea tree oil. Washed her bedding daily. Gave her a bath every three days to wash off old oil and reoiled her. Its messy and smelly but well worth the effort. We bought large containers of coconut oil from Sams club, Tea Tree oil from Walgreens and Neem Oil from asian markets and then we found large bottles on Amazon.
