Can Demodex mites be inherited?
No. The mites are not present on the fetus while the fetus is developing from an embryo in the uterus. However, if the mother has Demodex mites present in/on her skin, the mites can invade the new fetus’ skin immediately after birth. Since many dogs have Demodex mites present in their skin, and never actually develop noticeable skin lesions, the mother may not even be showing any signs of mites and yet transmit mites to the newborn pups.
