Changes in the Level of Plasma Cortisol, Progesterone and Total Testosterone in Developing Hairless Dogs

Abstract

Changes in the levels of plasma Cortisol, progesterone and total testosterone were examined in developing hairless and haired dogs. Cortisol levels in the hairless dogs seemed to be higher than those in haired dogs within the age of 4-5 weeks. No apparent changes were seen in the level of plasma progesterone between the groups of hairless females and haired females. Total testosterone levels in hairless males showed to be significantly lower than those in haired males at the age of 13-21 weeks. © 1992, JAPANESE SOCIETY OF VETERINARY SCIENCE. All rights reserved.
