Because of their superficial anatomical resemblance, the male dog seems to be suitable for studying the physiologic and pathological alterations of the bladder neck of human males. The present study was carried out to compare and contrast the muscular anatomy of the male dog lower urinary tract with that of humans. The complete lower urinary tract, including the surrounding organs bulb of penis, prostate, rectum and musculature of the pelvic floor were removed from adult and newborn male dogs and histologically processed using serial section technique. Based on our own histological investigations, three-dimensional 3D -models of the anatomy of the lower urinary tract were constructed to depict the corresponding structures and the differences between the species. The results of this study confirm that the lower urinary tract of the male dog bears some anatomical resemblance musculus detrusor vesicae, prostate, prostatic and membranous urethra to man. As with human males, the two parts of the musculus sphincter urethrae glaber and transversostriatus are evident in the canine bladder neck.
