What natural remedies or supplements for dog demodectic mange?

It depends on which type of mange you are actually treating. You are supplementing his skin well. The only other thing you can add is a weekly bath to help the skin and clean the coat. For demodex mange it is best to use a benzyl peroxide shampoo while scabies mange can be treated with any shampoo as it does not have to treat the deep hair follicles

Use an oatmeal type bath. This will help to moisturize the skin. You may also ask your veterinarian about using a special prescription shampoo which can help to clear out the pores and may be somewhat effective against the mites (though you need to continue your current treatment). I hope this helps and please feel free to post any additional questions.

After some research I have found that you can buy Ivermectin. It is very EASY to overdose so please be careful dosing your dog. It is dosed by weight. Follow the label instructions carefully and repeat every 14 days until one month after all the mange is gone. It is strongly recommended that you work with your vet on using this product.

Hello, I am sorry to hear about Scooby! If his skin is just dry with no lesions or hairloss or itching, you could consider adding a fatty acid supplement to his diet. Some are available over the counter for dogs, such as Welactin for dogs http://www.nutramaxlabs.com/dog/dog-skin-coat-health/welactin . You could also use a creme rinse and conditioner to moisturize his skin, such as epi-soothe https://us.virbac.com/product/dermatology/epi-soothe-cream-rinse

It probably is demodectic mange. I suggest you talk to your vet about putting him on Nexgard or Bravecto. Both are oral flea tablets that coincidentally also treat demodex. Easy to do and relatively inexpensive. They are prescription drugs though so you need to get them from your vet. So much easier than all the things you are doing and it works better. Hope this helps. Best wishes.

It is hard to treat with that extent without seeing a vet. He would need a skin scraping to diagnose it. The best thing at home is a weekly bath in a shampoo that has benzoyl peroxide as the active ingredient as this flushes the hair follicle. A vet can prescribe a monthly or once every 3 month medication to help get the mange under control if that is what they see

Amitraz (Mitaban) is one of 3 recommended treatments for demodecosis. It is applied every other week for 6 to 8 weeks or until there are 2 consecutive negative skin scrapes. The other two treatments are ivermectin injectable or oral given daily and Interceptor preventative administered daily. Both are administered for 6-8 weeks as well or when there are 2 consecutive negative skin scrapes. Protecting him from excess sunlight, which may cause sunburn on bare skin, is indeed recommended. Keep him in the shade, indoors or limit outside activity. An essential fatty acid supplement, such as a fish oil, may promote healthy skin and coat. Demodex infection may take months to fully resolve.
