My little girl Penny, she's 7 monthd old, was just diagnosed with a beginner's stage of Demodectic Mange. She's lost patches of fur in her inner thigh, her coat is dry, tiny bald spots on her and thinning around the eyes. The vet advised that the treatment can get very expensive and can be prolonged if she gets outbreaks. Anyone has experience with this that can provide me with advice? I'm getting worried. Also...any recommendations on pet insurance?
