It looks like is "red mange" won't show up in all pups- the female is the carrier- it is passed on through genes and is non cureable. I went through the same thing several yrs back and put all pups down and fixed the female!! Don't want this gene passed on! But u should have it checked by vet to make sure! It can be managed with several out breaks here and there- some worse than others! Good luck......
