A. If the mites and mange have not begun to clear up yet with the current treatment, it may be a good idea to speak with your vet about attempting a different treatment. Ivermectin is typically the main treatment for mange, while a topical ear solution is used for ear mites, however there are some alternate choices if those do not work or your dog cannot use ivermectin products (it should never be given to collie dogs).
Mange and mites can take a long time to recover until the skin begins to heal, and even if the underlying mite issue is resolved, the skin may have a secondary bacterial or fungal infection causing the sores to appear. Additional treatment or testing of the area can help. Ear mites are also very contagious and can be passed back and forth from pet to pet, so if you have other pets in the house, treating them for ear mites at the same time can help break the cycle and prevent them from spreading back and forth.
In some dogs, Demodetic mange *can* be genetic, making it more likely to be chronically there for a longer period of time. English Sheepdogs and Shar Pei dogs as well as other dogs with large folds in the skin may be more prone to this type.
