The life cycle of Sarcoptes scabiei var. canis was systematically investigated in vivo. The life cycle of females and males consisted of an egg, larva, protonymph, and a tritonymph that gave rise to an adult. Development from egg to adult required 10.06-13.16 days for the male and 9.93-13.03 days for the female. Egg incubation times were greater than 50.1 to less than 52.97 hr. Larval duration was between 3.22 and 4.20 days. The durations of protonymphal stages that were destined to become females and males were greater than 2.40 to less than 3.40 days and greater than 2.33 to less than 3.33 days, respectively. Tritonymphs destined to become females and males molted in greater than 2.22 to less than 3.22 days and greater than 2.42 to less than 3.42 days, respectively. During development, all life stages frequently left their burrows and wandered on the skin surface.
对犬疥螨生命周期进行了体内系统研究。雌螨和雄螨的生命周期均包括卵、幼虫、若虫前期和能发育为成虫的若虫后期。雄螨从卵发育到成虫需要10.06 - 13.16天，雌螨需要9.93 - 13.03天。卵孵化时间大于50.1小时至小于52.97小时。幼虫期为3.22至4.20天。发育为雌螨和雄螨的若虫前期持续时间分别大于2.40天至小于3.40天和大于2.33天至小于3.33天。发育为雌螨和雄螨的若虫后期分别在大于2.22天至小于3.22天和大于2.42天至小于3.42天蜕皮。在发育过程中，所有生命阶段都经常离开洞穴，在皮肤表面游走。
