Beth "Lesson learned, beware of breeders..." not fair, not right. Who is going to step forward and help you get out of this mess? Good , breeders on the forum. Poor dog . Let's get to it .
Unless you have the dog x rayed and confirmed by x ray , you can not say that the dog is dysplastic . If it is the dog in the avatar he looks scrawny , underfed . A dog that age should not have such a tight face with a prominent bony peak to his head .
Demodetic mange comes from stress, distress, malnutrition, stress from vaccinations poorly timed when the body system is already under siege.
What are you feeding the dog ? Get on to a good diet and let the immune system reverse things.
Shampoo with DEFENDEX VETiONX® Defendex? - Skin Soothing Pet Shampoo
. this is very safe -- repeat SAFE , both for yourself in handling it , and for the dog without marinating the dog in harsh , immune damaging chemicals.

Good protein . Good food . Sources of organic sulfur -- garlic within reason and MSM , better when derived from a natural source (Canada / USA ) made from brewing byproduct . Are the Health Benefits of MSM Related to Sulfur?

This will help with inflammation , help the joints, help cartilage and ligaments . Your dog may be lacking condition , muscle strength , and be loose as a goose , weak , giving him the swaying movement.

The dog can benefit from a good bone broth. Get chicken -- old stewing hen , necks, beef shank , bones (condoyles) put into the largest pot that you have . Cover with water . Bring to boil. With lid on reduce to simmer and let simmer all day (figuratively) till you have a condensed bone broth. Remove bones . Toss . Cool broth -- if you allow it to sit in the fridge the next morning you should have a wobbly gelly like mix . You can spoon this into the dogs GOOD food , or add to water to encourage hydration .
