A 3 year-old pregnant female Yorkshire terrier dog was presented with major complaints of polyuria and polydipsia. Laboratory tests found persistent hyperglycemia and glucosuria. Abdominal ultrasound study found 2 dead fetuses. Ovarian hysterectomy was performed to remove the dead fetuses. After ovarian hysterectomy, the level of blood glucose was returned to normal range. In addition, the clinical signs and urine glucose were all disappeared. Based on findings on laboratory tests and follow-up study, the case was diagnosed as gestational diabetes mellitus. To our best knowledge, this is the first case report describing a gestational diabetes mellitus of dog in Korea.

A nine-month-old intact female Maltese dog (body weight: 1.5 kg) presented with frequent syncopal episodes (1-2/day), exercise intolerance, and dyspnea. Cardiomegaly with marked dilation of right and left atria along with ascites was indicated on radiography. Tricuspid regurgitant jets (4.36 m/s), pulmonary regurgitant jets (3.4 m/s), left-to-right shunting flow at the ductus arteriosus, and an atrial septal defect were observed on echocardiography. A bubble study with agitated saline found right-to-left shunting at the interatrial septum. Based on diagnostic studies, the dog was diagnosed with right-to-left atrial septum defect (ASD) compounded with patent ductus arteriosus (PDA). The treatment was directed to reduce the pulmonary hypertension, improve cardiac performance, and lower fluid retention. Despite medical treatment for 2 months, the dog died of sudden cardiac arrest. Herein, we describe a very rare case of right-to-left ASD compounded with PDA.

A 4-year-old intact male Shih Tzu dog (5.4 kg of body weight) was referred with primary complaints of heart murmur and exercise intolerance. Diagnostic studies found severe valvular pulmonic stenosis (peak velocity of 6.4 m/s, pressure gradient 165 mmHg). The dog was treated with 3 cm (length) ${\times}$ 1.5 cm (diameter) of Palmaz biliary stent. The outcome of stent placement was favorable and remarkably reduced the severity of PS (6.4 m/s to 3.0 m/s of peak velocity). Clinical condition was remarkably improved with the absence of cardiac murmur, although mild pulmonic regurgitation existed from the day of stent placement. To our best knowledge, this case is the first clinical trial for treating PS with intravascular stent in Korea.

Uterine rupture is uncommon in small animals and can be caused by trauma, infection, dead fetus, or inappropriate obstetric techniques. A 4-year-old, intact female mixed-breed dog weighing 3 kg presented for elective ovariohysterectomy with a history of a motor vehicle accident two months previously. The patient showed no clinical signs of uterine abnormalities or evidence of pregnancy during physical examination. Clinical examinations, radiography, and ultrasonography revealed no significant findings. During ovariohysterectomy, a completely transected left uterine horn and dome-shaped ends were identified. The uterine layers were everted such that the endometrium could be seen outside the uterine horn. The dog recovered without post-operative complications and was discharged the following day. This report describes a rare case of an asymptomatic uterine rupture caused by trauma in a non-gravid dog.

Blood type in dogs is based on the antigen present on the red blood cell surface. Dog erythrocyte antigen 1 is a crucial red blood cell antigen in dogs, whereas the dog erythrocyte antigen 7 has been studied in limited dog breeds worldwide. To assess the prevalence of dog erythrocyte antigens 1 and 7 in 11 breeds in the Republic of Korea, 624 dog blood samples were examined for antigen detection. Overall, 520 dogs (83.3%) showed dog erythrocyte antigen 1 expression. The distribution varied from 50.0~100.0% according to the breed. Dog erythrocyte antigen 1-positive blood type was the highest in Chihuahua (100%), followed by Jindo dog (98.5%), and Sapsaree (95.3%). Dog erythrocyte antigen 7 was positive in 125 dogs (20.0%), and the positivity varied from 5.0~42.9% according to the breed. Dog erythrocyte antigen 7-positive blood type was the highest in Beagle (42.9%), followed by Chihuahua (37.5%), and Jindo dog (27.8%). The high prevalence of dog erythrocyte antigen 1 is because of the high proportion of Jindo dog and Sapsaree breeds that were mostly positive for the antigen. The high abundance of these breeds could be due to inbreeding and local breeding in the Republic of Korea. To our best knowledge, this study is the first to report on the prevalence of dog erythrocyte antigens 1 and 7 among various canine breeds in the Republic of Korea. The prevalence data obtained from this study may contribute to baseline information on veterinary transfusion medicine in small animal practice.

Effect of Jeo Ryong-Tang water Extract on Renal Function in Rabbit and Dog. In order to investigate the Pharmacological action of Jeo Ryoung-Tang on renal function, this study was performed in rabbit and dog, making use of it's water extract. Jeo Ryoung-Tang water extract (JRWE), when given into ear vein of rabbits, produced diuresis in a small dose, but antidiuresis in a large dose. Diuretic action of JRWE accompanied the increase of glomerular filtration rate (GFR), renal plasma flow (RPF) and amounts of $Na^+$ in exdreated in urin, but fractional excretion of filtered $Na^+$ was not changed. JRWE, when injected into proleg's vein of dog, produced diuresis, At this time, changes of renal function were similar to that of diuresis in rabbit. JRWE, when infused into a renal artery of dog, exhibited the diuresis in both kidney. It is thought that JRWE, when given into vein of rabbit or dog, induces the diuresis, and the mechanism of it's diuresis is the increase of renal plasma flow through secondary action by some endogenous humoural substance.

A nine-month-old Pomeranian dog with exercise intolerance and syncope was presented. The dog was depressed with grade 4 systolic murmur on cardiac auscultation. Based on cardiac examination, the dog was diagnosed with severe subaortic stenosis with involvement of the anterior mitral valve. ${\beta}-blocker$ administration was initiated and clinical signs were improved, but not fully resolved. Balloon valvuloplasty was performed and the dog survived for nearly one year without clinical sign and the cardiac troponin I level was normalized. This case describes successful management of severe subaortic stenosis in a small breed dog through balloon valvuloplasty.

This report presents two rare cases of gallbladder rupture in dogs with small gallbladders that did not result in bile leakage and their subsequent surgical treatment. The report includes a 5-year-old spayed female Chihuahua weighing 3.5 kg and a 9-year-old castrated male Poodle weighing 5.3 kg. Both dogs had elevated liver enzyme levels on blood chemistry. However, only the second dog (2) (Poodle) presented with hyperbilirubinemia and jaundice, whereas the first dog (Chihuahua (1)) did not display any specific clinical signs. Diagnostic imaging revealed a small gallbladder in both dogs, and the dogs were diagnosed with cholecystolithiasis (1) and extrahepatic biliary tract obstruction (2). No bile leakage-related abdominal effusion was observed. Gallbladder rupture and adhesion to the adjacent tissues were confirmed during cholecystectomy.

As with humans, overweight or obesity is a major health concern in the companion animal population. A cross-sectional questionnaire-based survey of dog owners attending primary small animal veterinary practices from different areas in Chuncheon, Kangwon province, Korea was undertaken to explore the relationships between socioeconomic and other relevant risk factors associated with canine obesity. In addition, the author was to estimate the prevalence of obesity compared to published literatures for dogs. Owners were asked about dog age, neuter status, feeding habits, dog exercise, household income and owner age. The body condition score (BCS) of the dogs was also assessed. Multivariable binary logistic regression was used to assess the association between BCS and potential risk factors controlling for confounding variables, using odds ratios (OR), 95% confidence intervals (CIs). A total of 275 dogs (136 males and 139 females) aged 1-12 years (mean age $5.6{\pm}3.7$ years) were surveyed in 2013. Of these, 46.9% of dogs (n = 129) were classed as an ideal body shape (BCS = 3), 30.9% (n = 85) were overweight (BCS = 4), 8.4% (n = 23) were obese (BCS = 5) and 13.8% (n = 38) were underweight (BCS = 1 or 2). Neutered males and spayed females had the highest prevalence of obesity (43.4% and 33.9%); intact females had the lowest prevalence of obesity (31.6%). In univariable model, risk factors associated with canine obesity are multifactorial and include owner income, owner age, age of dog, neuter status, frequency of feeding per day, frequency of snacks and consultation with veterinarian on dog's weight. In final multivariable logistic regression model, dogs whose owners reported no consultation with veterinarians for weight management were significantly more likely to be obesity than ideal (OR = 7.6, 95% CI, 4.2-13.8; p < 0.0001). This study showed a high prevalence of obesity in domestic companion dogs. Since this was a cross-sectional study with small samples, the association of canine obesity with risk factors warrants more research. To the author's best knowledge, this is the first Korean study on dog body condition and obesity.
