Absolutely YEA! Dice came from rescue with sarcoptic mange, it eventually infected Domino as well. Months of pesticide treatment to no avail. Went to Wholefoods, they reccomended Neem Oil. After 2 weeks of treatment, the boys started growing their hair back! The itching and red areas subsided, and we got to have our puppies back! And they got to have their good lives back! I will occasionally use this oil treatment for hot spots, and we use Neem Soap for bathing in Spring and Summer, it helps keep mosquitoes off of them too! Although the smell is something that takes getting used to, it wears away... It appears that Dice may have ringworm (small patch) on his belly, so he is getting NEEM bath today and a treatment tonight of the pure oil from Wholefoods... I 100% support this treatment for a braod spectrum of skin issues in dogs! :) Also, no harm in them licking it, it is natural!!!
I have fostered many cats with ringworm and the thing that knocks it out in days is neem oil. A bath twice a week for at least a month in a neem oil pet shampoo. Make sure you wash between toes which is how the spores are spread -- scratching the face and head. Then apply neem oil lightly directly to lesion twice a day for 3-4 days. It usually starts to heal the affected areas in 3 days.
