Two different methods of measuring the angle of inclination of the femoral head and neck were made and compared on 108 dogs. Resultant angles were not related to age, sex, or breed. The angle of inclination is related to technique of measurement, positioning, and anteversion angle.

The normal nasolachrymal systems of the dog (meso‐, dolicho‐, and brachycephalic) and cat were investigated by dacryocystorhinography and latex preparations. Nasolachrymal abnormalities associated with obstructions, deviations, a congenital defect and invasion of the system were demonstrated by dacryocystorhinography in four dogs and two cats. The value of dacryocystorhinography in the clinical evaluation of nasolachrymal diseases and in the diagnosis of nasal masses is presented. Résumé. Le systeme naso‐lacrymal normal du chien (méso‐, dolicho‐, et brachyocéphale) et du chat a été étudié par dacryocytsto‐rhinographie et d'après des préparations de latex. Les anomalies nasolacrymales dues à l'obstruction, aux déviations, aux lésions congénitales ou invasives ont pu être mises en évidence grâce à la dacryocysto‐rhinographie chez 4 chiens et deux chats. Les auteurs soulignent les avantages de cette méthode dans le diagnostic des affections naso‐lacrymales et en particulier dans celui des masses nasales. Zusammenfassung. Die normalen nasolachrymalen Systeme des Hundes (meso‐, dolicho‐und brachiocephal)und der Katze wurden mittels Dacryocystorhinographie und Latexpräparaten untersucht. Nasolachrymale Anomalitäten, die mit Obstruktionen, Abweichungen, einem con‐genitalen Defekt und Invasion des Systems verbunden waren, wurden durch Dacryocystorhinographie bei vier Hunden und zwei Katzen nachgewiesen. Der Wert der Dacryocystorhinographie bei der klinischen Untersuchung nasolachrymaler Krankheiten und für die Diagnose nasaler Massen wird erläutert.

Three intrapelvic urethral anastomosis techniques were performed on 12 mature male dogs to compare the degree of stricture. The intrapelvic urethra was transected 1 cm caudal to the prostate, and anastomosis was performed using either suturing of the urethra over an indwelling catheter, suturing of the urethra without an indwelling catheter, or apposition of the urethra without sutures over an indwelling catheter. Postoperatively, the dogs were evaluated using clinical urination patterns, biochemical tests, radiography, and pathology. Three of four suture-catheter dogs and one of four catheter-only dogs had normal urinary patterns. Stricture (25-84%) with urethral dilation or fistulas tracts was visible on retrograde, positive contrast urethrograms of 3 of 12 intact dogs 20 weeks after surgery, and on all 12 excised lower urinary tracts. Suture-catheter dogs subjectively had the least amount of stricture. All eight dogs (1 suture-catheter dog, 4 suture-only dogs, and 3 catheter-only dogs) with severe stricture (greater than 60% lumen diameter reduction) had histopathologic signs of chronic, inflammatory urinary tract disease, including four with chronic, ascending lymphocytic pyelonephritis. Hydroureter and hydronephrosis developed in two catheter-only dogs. Complete urethral transection resulted in some degree of stricture, regardless of technique used for anastomosis. Urethral anastomosis over an indwelling catheter appeared to result in a lesser degree of stricture and clinical and histopathologic derangement.
