Two dogs (Case 1: Poodle, 4 years old, spayed female; Case 2: Bulldog, 3 years old, intact female) were referred to us for treatment of vomiting; Case 1 had a history of acute vomiting that started 1 day prior to presentation, and Case 2 had a history of chronic vomiting that started 2 years prior to presentation. The vomiting did not respond to medication in the local animal hospital. Results from abdominal ultrasound examinations showed that case 1 had gastric wall thickening, and case 2 had no remarkable findings. For both cases, we performed gastrointestinal endoscopic examinations, and several biopsy samples were obtained from different gastric areas. On the basis of the results of histopathological examinations, both dogs were diagnosed with atrophic gastritis concurrent with a Helicobacter infection. Clinical signs improved after antibiotic therapy. This case report describes the clinical, endoscopic, and histopathological findings of atrophic gastritis concurrent with a Helicobacter infection.

A 5-year-old, intact male, poodle dog with right external auditory canal obstruction and subaural mass was presented. Physical examination revealed that right external auditory canal opening was absent and right head tilt was identified. Aspiration in right subaural mass revealed a small amount of dark brown exudate. Streptococcus canis and Staphylococcus spp. were identified on the microbial culture. Radiography of the skull was revealed absence of air-filled ear canal at the right external ear canal (EEC) level. Computed tomography (CT) revealed well capsulated, hypoattenuated mass in the right EEC region. On the contrast enhanced CT images, rim enhancement around the mass and ear canal obstruction were identified. Fluid attenuated material filled with right bulla. Mild thickening of the right tympanic bulla wall with mild lytic lesion of the ventral wall were found. Based on the images findings, the case was tentatively diagnosed as right external auditory canal atresia with otitis media. Total ear canal ablation and lateral bulla osteotomy was performed. The entire ear canal was removed, numerous hair in the canal and the thickening wall were founded. Right ear canal was sent for histopathological evaluation and found to otitis externa. The patient was followed up for two weeks and there were no complications. This report described the CT diagnosis of right EEC atresia with otitis media rarely reported in small breed dogs.

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.

The present study aimed to examine the effect of dietary Ptecticu tenebrifer powder mixtures as pet dogfeed ingredients on crude fat and ash digestibility. Three groups of feeds Feed A, Feed B, and Feed C supplied from three farms were fed to a total of 45 dogs. The dietary Ptecticu tenebrifer powder mixture were prepared by mixing 25 g of Ptecticu tenebrifer powder with 100 g of canned food. Feed A, Feed B, and Feed C containing dietary Ptecticu tenebrifer powder mixtures were fed to 15 dogs of each breed of bichon, poodle, and chihuahua that were divided into three groups following a completely randomized design. For measuring the crude fat and crude ash digestibility, manure of each dog breed from each group were collected. Crude fat digestibility was not statistically significant among the dog breeds fed with feed C (p>0.05), but overall there was a statistical difference between the feed and the group by dog breed (p<0.05). In terms of crude ash digestibility, the three types of feed showed differences with respect to dog breeds (p<0.05). However, the group with no significant difference was observed in Feed B by dog breed (p>0.05). In conclusion, feeding Ptecticu tenebrifer powder mixture to dog breeds had no positive effect on the crude fat and ash digestibility and can be used as pet dogfeed ingredients.

Objective: The present study analyzed the influence of co-transferring embryos with high and low cloning efficiencies produced via somatic cell nuclear transfer (SCNT) on pregnancy outcomes in dogs. Methods: Cloned dogs were produced by SCNT using donor cells derived from a Tibetan Mastiff (TM) and Toy Poodle (TP). The in vivo developmental capacity of cloned embryos was evaluated. The pregnancy and parturition rates were determined following single transfer of 284 fused oocytes into 21 surrogates and co-transfer of 47 fused oocytes into four surrogates. Results: When cloned embryos produced using a single type of donor cell were transferred into surrogates, the pregnancy and live birth rates were significantly higher following transfer of embryos produced using TP donor cells than following transfer of embryos produced using TM donor cells. Next, pregnancy and live birth rates were compared following single and co-transfer of these cloned embryos. The pregnancy and live birth rates were similar upon co-transfer of embryos and single transfer of embryos produced using TP donor cells but were significantly lower upon single transfer of embryos produced using TM donor cells. Furthermore, the parturition rate for TM dogs and the percentage of these dogs that remained alive until weaning was significantly higher upon co-transfer than upon single transfer of embryos. However, there was no difference between the two embryo transfer methods for TP dogs. The mean birth weight of cloned TM dogs was significantly higher upon single transfer than upon co-transfer of embryos. However, the body weight of TM dogs did not significantly differ between the two embryo transfer methods after day 5. Conclusion: For cloned embryos with a lower developmental competence, the parturition rate and percentage of dogs that remain alive until weaning are increased when they are co-transferred with cloned embryos with a greater developmental competence.

Dogs exhibit patterns of health issues that vary by life stage. An understanding of disease incidence with respect to breed and age/life stage could be an important component of canine health management and welfare. This study aimed to describe the age-specific disease incidence of 3 small dog breeds that attended veterinary clinics in the Republic of Korea, based on data from electronic veterinary medical records (EVMRs). A total of 40,785 EVMRs from Maltese (n = 21,355), Miniature Poodle (n = 11,658) and Shih Tzu dogs (n = 7,772) were analyzed. Common health problems in 3 small dog breeds were 'diseases of the skin' and 'diseases of the ear,' respectively. Among dogs aged ≤ 3 years, 'preventive medicine' was the most common cause cited for veterinary clinic visits. Among dogs aged 4 to 8 years, the most frequent health problems were 'diseases of the skin.' Among dogs aged 9 to 13 years, 'heart diseases,' 'kidney diseases,' 'mammary gland tumor,' and 'neoplasia (unspecified)' were considerably more frequent, compared to the rates in dogs ≤3 years. Among dogs aged ≥ 14 years, 'heart diseases' and 'sneezing/cough' were the main health problems. In all breeds, the frequencies of 'diseases of circulatory system,' 'diseases of respiratory system,' 'diseases of the nervous system,' 'endocrine' and 'neoplasia' increased rapidly with aging. This surveillance could inform strategies for disease screening tests and management based on life stage in these dog breeds and enable more effective health management.

A 10-year-old, castrated poodle dog presented with a cough for 2 weeks, and the cough initially developed since very young age. On radiographs, pneumothorax was noticed by characteristics of radiolucent area without pulmonary markings along the thoracic wall and diaphragm, retracted lung lobes from the thoracic wall and severely decreased volume of the left cranial lung lobe with disconnected bronchus. Computed tomography (CT) findings identified several pulmonary air-filled cysts and collapsed lung with abnormal shape and non-tapered end of bronchus, bronchioles at the accessory lobe and left cranial lobe. Also, pneumothorax, pneumomediastinum and subcutaneous emphysema were found. Imaging diagnosis was the spontaneous pneumothorax caused by ruptured emphysematous bullae associated with congenital bronchial cartilage abnormality or bronchial tree malformation. On surgery, hypoplasia of the left cranial lobe, right middle lobe, and accessory lobe with a bulla where air was leaking was identified. The accessory lobe was partially resected and bronchial cartilage hypoplasia was confirmed by histopathologic examination.

An eight-year-old, castrated male, Poodle dog was presented with a bite wound in the neck region. Clinical examination revealed non-ambulatory signs of tetraparesis with deep pain, and upper motor neuron changes in all limbs. Fractures of the transverse process of C1 and the dorsal spinous process of C2 were observed on the radiographs and the computed tomography (CT). Conservative therapy was performed for 1 week. However the neurological problems were not alleviated until 7 days after injury. The owners agreed to perform surgical stabilization. The surgical stabilization was performed 7 days after presentation. Ventral stabilization was performed with screws, K-wires and bone cement. The dog stood up independently after 4 weeks and was able to walk 6 weeks postoperatively. In this report we suggest that using combined stabilization techniques are effective for this type of cervical fracture in which the dorsal and ventral structures of the vertebra are severely disrupted.

An 8-month-old, 3.5 kg intact female Toy Poodle was presented for non-weight-bearing lameness on left hindlimb. In radiological testing, left proximal tibal type II Salter-Harris physeal fracture and fibular fracture were seen. Following open reduction, the fracture was stabilized with cross-pins, tension band wires, and a hinged transarticular external skeletal fixator (HTAESF). The range of the HTAESF was increased to $25^{\circ}$ at 7 days postsurgery and to $70^{\circ}$ at 14 days post-surgery. The HTAESF was removed 3 weeks after surgery. At 6 weeks post-surgery, the fracture was successfully healed with no complications and the patient recovered a normal gait. Seven months post-surgery, the patient had a normal gait and a normal stifle joint range of motion compared to the contralateral normal limb. This is a case in which the combined use of cross-pins, tension band wires, and HTAESF was successful for treatment of a proximal tibial physeal fracture in a dog. It is thought that these methods are beneficial for stability of fracture site and recover of joint's normal range of motion through early joint movement.

A 12-year-old male poodle weighing 2.0 kg presented for evaluation of right thoracic limb lameness. The owner reported that the dog showed recurrent bilateral shoulder joint luxation after a car accident for a year. Recently, the left shoulder joint appeared well maintained, but right shoulder joint luxation was exacerbated. On physical examination, the dog showed non-weight bearing lameness on the right thoracic limb. Craniocaudal radiographic views revealed medial displacement of the right humerus. Mediolateral radiographic views revealed overlap of the glenoid cavity and humeral head. Muscle atrophy of the right thoracic limb, reduced biceps brachii muscle tendon tone, a tear of the medial glenohumeral ligament, and a rupture of the subscapularis tendon were identified intraoperatively. Transposition of the biceps muscle tendon was performed. However, at 7 days, there was evidence of right shoulder reluxation on radiographs. The second surgery was performed with two $2mm{\times}6mm$ cortical bone anchors and a $4mm{\times}6mm$ cancellous bone anchor placed in the cortical bone of the distal scapula and the cancellous bone of the proximal humerus respectively. Two scapular bone anchors were then connected with a humeral bone anchor using heavy nylon suture to minimize shoulder abduction range of motion. On radiographs right after surgery and 6 weeks after surgery, the affected limb revealed no evidence of medial shoulder luxation. At 6 months, no evidence of lameness was noted on the right thoracic limb.
