I "inherited" my Kitana, who is an approx. 1.5 year old pitbull. My son rescued her from an animal shelter but couldn't afford to take her to the vet. Needless to say, since I already have many animals, I had to take her. She has demodectic mange and the vet has put her on ivermectin and antibiotics. The vet said she would likely have to be on this invermectin for a long time. So I googled this and was not happy to discover that this is not the best idea. I don't want to cause this sweet animal any further harm and I understand it will weaken her immune system even more. So, I've seen some all natural remedies online, but am skeptical. Any advice for a new pitbull owner is very appreciated.
