Trans epidermal water loss (TEWL), skin hydration status and pH were determined in 14 skin regions of five healthy male Beagle dogs (2-4 years) both before and after anaesthesia. Trans epidermal water loss was highest for the footpad and head and lowest for the inguinal region. Skin hydration status was higher in the ear but did not vary significantly in other regions. Skin pH was usually alkaline with the highest values on the lower back and tail. Following anaesthesia, TEWL and skin hydration were significantly lower on the head, upper back and footpad, and upper back and elbow respectively, while skin pH was unaffected by this procedure. While measurement of pH would seem to be valid anywhere on the body in anaesthetized dogs, regional factors should be considered when interpreting TEWL and skin hydration values and when treating regional skin diseases in veterinary practice.
在五只健康的雄性比格犬（2 - 4岁）麻醉前后，测定了其14个皮肤区域的经表皮水分流失（TEWL）、皮肤水合状态和pH值。脚垫和头部的经表皮水分流失最高，腹股沟区域最低。耳部的皮肤水合状态较高，其他区域无显著差异。皮肤pH值通常呈碱性，下背部和尾部的值最高。麻醉后，头部、上背部和脚垫的TEWL以及上背部和肘部的皮肤水合显著降低，而皮肤pH值不受该操作影响。虽然在麻醉犬的身体任何部位测量pH值似乎都是有效的，但在兽医实践中解释TEWL和皮肤水合值以及治疗局部皮肤疾病时，应考虑区域因素。
