I had 2 rescue GSD with generalized Demodex. The male finally cleared up at about 1 year but his sister didn't clear up until about 3 years old. At it's worst she had no hair - just bleeding skin. Spay and neutering was done, amitraz dips, ivermectin given orally, and antibiotics for secondary infection. I also switched to a raw diet to help with their immune system. One thing I think heavily contributed to my female finally clearing up was the loss of another GSD female that did not get along with her. Had to always keep them separated. When she died Rosie's skin finally started clearing up. Stress affects the immune system. She's now almost 10 and has a beautiful coat. After 3 years never broke out again. If it's more than just a few small spots should follow vet's advice. Will still probably clear up by the time your dog reaches about a year old. Demodex is not uncommon in puppies.

I've been searching for what the age cutoff is for calling it "juvenile" demodicosis (or what they mean when they say "puppy" in a demodex discussion).
Finally found "under age two" in Merck.
"Nummular" means "coin-size and coin-shape." (I had to look that up.)
"Pruritis" is itchiness. "Erythema" is redness, rash. "Comedones" are blackheads.
Two clinical forms (localized and generalized) of the disease exist. Localized demodicosis occurs in dogs <2 yr old, and most of these cases, especially the nummular forms, are thought to resolve spontaneously. Lesions consist of areas of focal alopecia, erythema and/or hyperpigmentation, and comedones. Pruritus is usually absent or weak. A percentage of these cases, especially the diffuse localized forms, progress to the generalized form. Generalized demodicosis is a severe disease with generalized lesions that are usually aggravated by secondary bacterial infections (pyodemodicosis). Accompanying pododermatitis is common. Dogs can have systemic illness with generalized lymphadenopathy, lethargy, and fever when deep pyoderma, furunculosis, or cellulitis is seen. Deep skin scrapings reveal mites, eggs, and larval forms in high numbers. Whenever generalized demodicosis is diagnosed in an adult dog, medical evaluation to identify an underlying systemic disease should be pursued.
Nummular localized demodicosis can be left untreated. The prognosis for this form is usually good, and spontaneous recovery is frequent. In contrast, treatment is required in cases of diffuse localized demodicosis (which can generalize), generalized demodicosis, pyodemodicosis, and pododemodicosis, for which prognosis is always guarded.

Thanks for the link and info Connie. He seems to have just a few more spots than what would be considered localized but nowhere near as bad as what would be considered generalized. I guess I'll do another dip or two and see how he looks after that.
Preventic tick collars can resolve localized cases of demodex - Amitraz is the effective ingredient in the collar and it works it's way into the skin pores very similar to spot on flea treatments.
