my dog has mange any nature treatment for mange ?

Well, if you are saying your dog has mange, then I am assuming that you have already been to the vet and are looking for like you say a "natural" treatment instead of the conventional treatment you have been explained to by your vet, right? Well, you gotta go with what your vet has prescribed because if by the time you notice your dog has mange it’s probably very localized to warrant THAT vet visit or perhaps generalized to the point where you maybe have secondary problems like skin pore infections. It’s hard because your question is not accompanied by any explanation.
I can’t tell you how to treat your dog, but I can tell you what I’ve done with my own dogs and dogs that I have rescued off the street to rehome. Keep in mind that even though I start natural treatment, I have ALWAYS taken the dog in for a vet visit & for scraping to know which kind of mange (if any mites are still alive) and if I have to go conventional, then I’ve never deprived any of the dogs of treatment that a vet has told me to give a dog.
The first thing to understand is that mange is a mite. These mites are on you already, they are on everybody. They are also on your dog already & they are on all dogs. The thing is that the body (human or dog) has an immune system and this immune system is supposed to keep the growth of mange mites under control. If the mange mites on skin get out of control, then you have an overgrowth. It’s the same as like when women get a yeast infection. There’s good bacteria & bad bacteria. If the good bacteria doesn’t keep the bad bacteria in balance, then there is an overpopulation – yeast.
So, now your dog has mange and you want to treat it. But have you asked yourself ‘Why did my dog come down with it to begin with?’. Yes, your dog can catch it from other dogs (sarcoptic) and yes your dog can inherit it (demodectic), but I’ve had dogs that won’t catch sarcoptic and I have in fact slowed the enragement of demodectic mange in puppies.
There are dips your vet might recommend and of course do what your vet says, but while the vet takes care of that end, I work on the immune system of the dog, which is why the dog has an overpopulation of mites to begin with. First thing is I upgrade the dog food to something single source protein & single source carbohydrate, no wheat, no soy, & no corn. I discontinue all treats. No canned. Your vet may recommend something or there are kibbles that are considered tops. Next is I work on balancing the T1 & T2s in the gut. There’s a book called "The Makers Diet". It will tell you how to do this. I add kelp or kelp/alfalfa (50/50). I get it at the health food store or there are two products out there one called Kelp-Help & the other SeaMeal. If the vet prescribed anti-biotics for secondary infections, then I will give the dog all of them and when the dog is finished with the antibiotics, then I will give the dog probiotics (as soon as I finish the probiotic that contains an HSO – from The Makers Diet book). I will also give the dog digestive enzymes because commercial kibble is lacking in that.
With puppies that have very very very local cases of it say perhaps maybe a few small bare spots on their legs or starting to loose hair around eyes & mouth, then I mix up into distilled water some tea tree oil & lavender oil (more tea tree than lavender). I’ll wipe it onto all the areas I see several times a day until I can get the puppy(s) to a vet and usually by that time my vet has said just keep doing it because by the time I get there the hair has started to grow back (because it’s been very very very mild local cases of it). With more hardy cases of it, the vet has to prescribe a dip of insecticide and with one kind of mange the vet has to do it. There was one dog though that I rescued from somebody that had already been through the vet dips & I took the dog for rehoming but the hair wasn’t growing back, so I sprayed the tea tree/lavender/water mix on this dog in those areas twice a day but I think more important is that I upgraded his diet which is what he really needed and he started growing his hair & got himself a good home because he ended up looking very pretty. But then there was one dog that somebody had put her through treatment at the vet but she relapsed, so I ended up with her and I did everything along with my vet and she relapsed again. Turned out she had an underlying immune deficiency disease & we lost her. Then there was, now that I think about it one dog that the vet put her on ivermectin & I didn’t believe him so I looked it up on the internet and there was some info about that. I held my breath (doing what the vet said), but that dog recovered just fine. So, it’s important to get with your vet because you don’t know how they will want your dog treated. But along with the vet seeing the dog, it’s also important to concentrate on your dogs diet too.
