A six-month-old Boston terrier presented with an extruded penis caudally, incompletely formed preputial sheath, bifid scrotum, retained testicle and deformity of the os penis. On physical examination, the urethral orifice was located on the surface of the perineum and a fibrous band was observed running from the grans to the urethral orifice on the perineum. The dog also had urethritis that was infected by ascending bacteria entering through the contaminated urethral orifice. Corrective surgery was undertaken to excise the external genitalia and retained testicle. The prepuce, penis and retained testicles were successfully excised. After the urethral orifice was cleaned periodically and antibiotics were administrated, recurrent urethritis disappeared. Using this therapeutic regime it is not necessary to reconstruct the anomaly located urethral orifice, if the location of urethral orifice is not the cause of recurrent urethritis and urinary incontinence.

A 6-year-old female Boston terrier dog was presented with seizure episode, forelimb paraparesis, excessive panting, and ataxia. On physical and neurological examination, episcleral vessel engorgement, delayed postural reaction, delayed pupillary light reflex (both direct and consensual), and crossed forelimb were noted. Serum biochemical profiles were not remarkable other than mildly elevated hepatic enzymes. On cerebrospinal fluid analysis, elevated protein concentration was observed. In magnetic resonance imaging scans, the left frontal brain lesion with ring enhancement strongly suggested the presence of intracranial tumor. Concurrently, secondary hydrocephalus and syringomyelia were also observed. The dog was euthanized at 4 months after initial presentation because of aggravated neurological signs. This case was definitely diagnosed as an intracranial anaplastic oligodendroglioma based on postmortem histopathologic examination.

A 7-year-old intact male Pitbull terrier dog was presented with complaints of marked abdominal distension and severe exercise intolerance. Diagnostic studies found a right-sided cardiomegaly with marked dilation of pulmonary arteries, diffuse interstitial pulmonary infiltration and heavy worm burden in the right atrium and ventricle. Color and spectral Doppler echocardiography also revealed tricuspid and pulmonic regurgitation indicating severe pulmonary hypertension. The 104 heartworms were removed by interventional extraction using a loop snare (Snare, Boston Scientific, USA) through external jugular vein. After heartworm removals, the clinical condition of this dog was remarkably improved. To author's best knowledge, this is the first case of interventional heartworm extraction using a loop snare in Korea.

A 7-year-old castrated male Boston terrier dog was referred due to dyspnea and unilateral cervical mass. On physical examination, mass on left submandibular region was palpated. CT findings revealed this case could be the tumor originated from left lingual vein. The client refused further treatment and the patient expired because of respiratory failure 10 days after presentation. On necropsy, a well-defined firm mass which located in the left side of larynx was detected. Histopathological findings for the mass indicated polygonal tumor cells arranged in nest and separated by fibrovascular septa. We performed immunohistochemisry to evaluate of chromogranin A and tumor cells showed positive immunoreactivity for chromogranin A. Based on computed tomography (CT), histopathological and immunohistochemical findings, this case was definitely diagnosed to paraganglioma of the body on the lingual vein. This report describes the clinical findings, CT imaging characteristics, histopathologic and immunohistochemical features of paraganglioma arised from lingual vein in a dog.

To determine the prevalence of breed, age, and sex of canine primary glaucoma by comparing previous reports in Korea. We included the medical records of dogs diagnosed with primary glaucoma who visited the veterinary medical teaching hospital of Seoul National University (SNU) from January 2011 to December 2020 and investigated their breed, age, and sex. All the patients underwent a full ophthalmic examination. We analyzed the results using a binary logistic regression analysis based on the Jindo dog, which was close to the mean value of the primary glaucoma incidence rate. Of the 14,587 dogs treated at the veterinary medical teaching hospital of SNU, 107 (0.73%) were diagnosed with primary glaucoma. Glaucoma occurred in 14 breeds, including the American Cocker Spaniel, Shih Tzu, Maltese, Pomeranian, Jindo dog, Mixed Breed, Pekinese, Toy Poodle, Samoyed, Shiba Inu, Miniature Pinscher, Boston Terrier, Labrador retriever, and Yorkshire Terrier. The mean age of onset of primary glaucoma was 7.8 ± 2.3 years. Primary glaucoma was observed in 53 spayed females, 11 females, 38 castrated males, and five males. Regardless of neutralization, the ratio of females to males was 1.5:1. This study showed that primary glaucoma was significantly higher in American Cocker Spaniels and higher in Shih Tzus than other breeds in Korea; they had the highest incidence of primary glaucoma at 7 and 8 years of age, respectively. Therefore, the two breeds should be carefully monitored for the occurrence of primary glaucoma when they approach 7 years of age.
