THERMAL CUTANEOUS VASOMOTOR RESPONSE IN DOGS

Abstract
The thermal cutaneous vasomotor response of dogs has been studied using a procedure similar to the clinical Gibbon-Landis test. The response as measured by skin temp. changes of the ear of the dog resembles closely the response observed in similar circumstances of the fingers and toes of men. Thermal cutaneous vasoconstriction in the dog is undulatory and can occur with a sharp drop in rectal temp. Thermal cutaneous vasomotor activity is abolished by sympathectomy. The sympathectomized dog depends on sweating and panting for its control of body temp.
