Abstract: 
The aim of this study was to identify the functional anatomical structures of the canine penis during and after erection to demonstrate the respective changes to provide a basis for further examinations of pathological conditions like priapism. Additionally, a gray-scale analysis was performed to quantify results from the ultrasound examination. In total, 80 dogs were examined. In group (Gr.) A, 44 intact or castrated dogs were examined, and in Gr. B, 36 dogs were examined during erection and after complete detumescence of the penis. The following parameters were assessed: (1) using physical measurements: length of the Pars longa glandis [Plg] and length of the Bulbus glandis [Bg]; and (2) using ultrasound: total penile diameter, width of the erectile tissue of the Plg, diameter of the Corpus spongiosum [Cs] including the penile bone and urethra, vertical diameter, circumference of the penis, cross-sectional area, and area of the Cs including the urethra. The mentioned parameters could be assessed in all dogs of Gr. A and Gr. B with the only exception being the urethra that could be visualized using ultrasound in some dogs only and predominantly in the erected penis (Gr. B). Concomitantly, the erectile tissue of the Plg and the Cs was more heterogenous and hypo- to anechoic during erection compared with dogs in Gr. A and Gr. B after detumescence. Comparing the results in Gr. B, the length of the Plg and the Bg were decreased approximately 40.6% and 38.0%, the total width of the penis 40.5%, the total width of the erectile tissue of the Plg 48.0%, and the width of the Cs 15.6% during detumescence compared with erection. Comparing the decrease in size at the different locations (apex penis, middle of Plg, middle of Bg) for vertical diameter, total circumference, and cross-section area, it was largest at the Bg. B-mode ultrasound is a suitable tool to investigate not only the morpho-functional structures of the resting canine penis, but also of the erected and detumescent penis, and to investigate the underlying changes during erection and detumenscence.
