Answer
Demodex mites are controlled by the puppy's immune system.  All dogs have these mites, but most have normal immunity, so the mites don't cause any problems.  Until your puppy's immune system is fully developed, the mites can reproduce and cause damage to the hair follicles.  If the pup's immune system does not become fully competent, there will be continuous problems with demodex.  That can happen in 10% of all dogs.
