A castrated male Yorkshire Terrier dog was presented for urinary incontinence and constipation. On physical examination, the dog showed difficult urination. There were no neurological abnormalities and no bacterial detection on urinalysis. Rectal examination revealed a regular, normal-sized prostate. Urethral catheterization was performed easily. Excretory urography and retrograde positive contrast urethrocystography showed displacement of the urinary bladder to the intrapelvic region. There was no evidence of an ectopic ureter. A tentative diagnosis of urethral sphincter mechanism incompetence accompanied with a pelvic bladder was made. Cystopexy was decided to place the urinary bladder to its normal position. The neck of the urinary bladder was anchored to the body wall and prepubic tendon using mattress sutures. Additional sutures were placed to appose the lateral part of the urinary bladder and abdominal wall. A simple interrupted suture was placed to tack the apex of the urinary bladder on the abdominal incision line. A urinary catheter was placed in the urinary bladder to provide post-operative evacuation. The catheter was removed when the dog was able to urinate with minimal straining at 3 days post-operatively. The owner reported that the dogs showed normal urination without straining at 3 days after the catheter was removed. Excretory urography revealed that the urinary bladder was located on its normal position at 2 months post-operatively. Subsequent communication with the owner by telephone revealed that the dog was in good urination at 3 years 11 months post-operatively.

A 6-month-old, intact male Great Pyrenees (35 kg) was referred with 2 weeks continuous left forelimb lameness to the Chonbuk Animal Medical Center, College of Veterinary medicine, Chonbuk National University. The lameness became worse three days before being referred to the hospital. Upon the physical examination, the patient had pain when the left shoulder joint was palpated, and the lameness was visible in the left forelimb during ambulation on gait examination. There were no remarkable findings on radiological and neurological examination. Osteochondritis dissecans (OCD) was suspected based on medical history and gait tests. As a definitive diagnosis could not be made, exploratory arthroscopic surgery was performed to examine the inside of the shoulder joint. During the operation, mild bicipital tenosynovitis, synovitis and OCD which was located on the caudal medial area of humeral head were revealed. Arthroscopic procedures were used for the treating OCD, including the removal of the OCD flap and debriding of the subchondral defect until hemorrhaging by use of an electrical burr. The patient was discharged a day after surgery. After 2 weeks, the patient again presented at the hospital due to complications, including inflammation of the surgical lesion because of licking and seroma within the subcutaneous tissue. Antibiotics were administered and an aseptic bandage was applied. And simple surgical operations were performed for the removal of the cyst and seroma. Eleven weeks following arthroscopy, the lameness was completely resolved. Arthroscopy has the advantage of allowing gross examination inside the joint capsule. Due to this advantage, arthroscopy is one of the best advanced options for diagnosis in dogs with undiagnosed joint pain.

As pets such as dogs and cats have been accepted as family members and companions, calling them companion animals has become more and more common. As the trend of identifying companion animals with humans and treating them as members of a family is spreading, people are more concerned about food, health, and leisure for companion animals, searching for expensive products, and accelerating the growth of related businesses. This study collected data by conducting an online questionnaire targeting customers who visited online companion animal shopping malls. Data collected only for people who have purchased companion animals at least once in online shopping malls for companion animals were used for empirical analysis. Questionnaires from 205 people were collected, but a total of 198 copies were used for the analysis, excluding the questionnaire that gave an insincere response. The results are as follows. First, through exploratory factor analysis, it was confirmed that the service quality factors of the online shopping mall for companion animals consisted of four dimensions: communication-transaction, safe security, design, and information provision. Second, it was found that communication-transactions, information provision, design, and safe security, which are the service quality factors for companion animal online shopping malls, all have a significant positive (+) effect on customer satisfaction. Third, it was confirmed that customer satisfaction in online shopping malls for companion animals had a significant positive (+) effect on loyalty. Fourth, in the relationships between service quality factors (communication transaction, safety security, design, information provision) and loyalty of companion animal online shopping mall, it was confirmed that customer satisfaction has complete mediating effects.

Canine influenza virus (CIV) induces acute respiratory disease in dogs. In this study, we aimed to determine the signaling pathways leading to the induction of IFN-β in a canine respiratory epithelial cell line (KU-CBE) infected with the H3N2 subtype of CIV. Small interfering RNAs (siRNAs) specific to pattern recognition receptors (PRRs) and transcription factors were used to block the IFN-β induction signals in H3N2 CIV-infected KU-CBE cells. Among the PRRs, only the TLR3 and RIG-I expression levels significantly (p < 0.001) increased in CIV-infected cells. Following transfection with siRNA specific to TLR3 (siTLR3) or RIG-I (siRIG-I), the mRNA expression levels of IFN-β significantly (p < 0.001) decreased, and the protein expression of IFN-β also decreased in infected cells. In addition, co-transfection with both siTLR3 and siRIG-I significantly reduced IRF3 (p < 0.001) and IFN-β (p < 0.001) mRNA levels. Moreover, the protein concentration of IFN-β was significantly (p < 0.01) lower in cells co-transfected with both siTLR3 and siRIG-I than in cells transfected with either siTLR3 or siRIG-I alone. Also, the antiviral protein MX1 was only expressed in KU-CBE cells infected with CIV or treated with IFN-β or IFN-α. Thus, we speculate that IFN-β further induces MX1 expression, which might suppress CIV replication. Taken together, these data indicate that TLR3 and RIG-I synergistically induce IFN-β expression via the activation of IRF3, and the produced IFN-β further induces the production of MX1, which would suppress CIV replication in CIV-infected cells.

In this study, the status of damage by subterranean termites and their management according to the region and type of domestic wooden cultural properties were identified. This was based on the survey reports of agencies conducting regular nationwide and regional monitoring of subterranean termites. In addition, using geographical information system (GIS) based on the survey contents, a map was constructed of termite infestation and its progress on 2,805 wooden cultural properties that were surveyed nationwide. Based on the map produced, a total of 486 cases of termite infestation were confirmed in wooden cultural properties during 2018-2019, of which 143 cases (approximately 29.4%) were confirmed to be owing to the invasion of termites in the ground and infestation of wood materials. A web platform and an application using a mapping application program interface were created to increase accessibility to the investigated damage status data. The methods employed by each institution for investigating and monitoring the invasion of termites in the ground included the use of detection dogs, visual observation, installation of wood specimens made of pine, and microwave equipment. However, it was confirmed that monitoring and survey methods were not applied to determine the territorial range of the subterranean termite colonies. Accordingly, the use of dyeing and mark-release-recapture methods were deemed necessary to understand the current status, such as calculating the scope of the target wooden cultural property, when monitoring subterranean termite colonies.

Mammary gland tumors are one of the most common cancers in female dogs, and there are various types of cells depending on the tumor type. Complex carcinoma consists of a combination of luminal epithelial and myoepithelial cells with intra-tumoral heterogeneity. However, the origins of these tumor cells and their effects on the malignancies of tumors have not been identified. Recently, it has been reported that cancer stem cells, identified in several types of human tumors, are involved in tumor heterogeneity and may also contribute to malignancies such as tumor recurrence and metastasis. Interestingly, cancer stem cells share several abilities of self-renewal and cell differentiation into multiple types of cancer cells, but they have abnormal genetic mutation and signal transduction pathways to regulate the maintenance of stem cell characters. Moreover, it is known that these cell populations contribute to cell metastasis as well as cell resistance against chemo- and radio-therapeutics that promote tumor recurrence. The existence of cancer stem cells might explain the intra-tumoral heterogeneity and cancer aggressiveness during tumorigenesis in canine mammary gland tumors. This review summarizes the characteristics and types of canine mammary gland tumors, the definition of tumor stem cells, methods of isolation, and clinical significance.

A 6-year-old, spayed female, Maltese dog with tachypnea and dry cough was presented to Gyeongsang National University Veterinary Medical Teaching hospital. On physical examination, its respiration rate was 132 per minute. Decreased partial pressure of oxygen, partial pressure of carbon dioxide, and hyperlactatemia were found on arterial blood gas analysis. Its diastolic blood pressure was 80 mmHg. Auscultation revealed arrhythmia. Electrocardiogram revealed P pulmonale, P mitrale, and ventricular premature complexes. Thoracic radiographs revealed mild enlargement of both atrium and moderate enlargement of the left ventricular. There was also a moderate alveolar pattern in the right and caudal part of the left cranial lung lobe. Two-dimensional echocardiography showed enlargement of generalized four chambers without remarkable findings of valvular degeneration. M-mode echocardiography showed decreased left ventricular fractional shortening and enlarged left ventricular internal diameter at both end-systolic and end-diastolic. Color-flow Doppler imaging revealed eccentric turbulent flow starting below the left ventricular outflow tract and extending into the left atrium during systole. Spectral Doppler recordings revealed a high velocity flow through the mitral, tricuspid, aorta, and pulmonic regurgitation. Restrictive transmitral flow revealed high E-wave velocity, short E-wave deceleration time, and reduced A-wave velocity. There was also low ejection velocity thorough left ventricular out tract flow. Based on echocardiographic examination, dilated cardiomyopathy was the tentative diagnosis. The dog was medicated with inotropes, angiotensin converting enzyme inhibitor, and diuretics. At the 10-day following-up, the dog died suddenly. This report describes echocardiographic diagnosis and prognosis of dilated cardiomyopathy rarely reported in small breed dogs.

Although registration of dogs is mandatory according to the revision of the Animal Protection Act, the registration rate is low due to the inconvenience of the current registration method. In this paper, a performance improvement study was conducted on the dog face recognition technology, which is being reviewed as a new registration method. Through deep learning learning, an embedding vector for facial recognition of a dog was created and a method for identifying each dog individual was experimented. We built a dog image dataset for deep learning learning and experimented with InceptionNet and ResNet-50 as backbone networks. It was learned by the triplet loss method, and the experiments were divided into face verification and face recognition. In the ResNet-50-based model, it was possible to obtain the best facial verification performance of 93.46%, and in the face recognition test, the highest performance of 91.44% was obtained in rank-5, respectively. The experimental methods and results presented in this paper can be used in various fields, such as checking whether a dog is registered or not, and checking an object at a dog access facility.

Purpose: The aim of this study was to analyze by age group the characteristics of patients with dog bite injuries, as well as determine which factors were associated with wound infections in those patients. Methods: We reviewed patients with dog bite injuries who presented to Gachon University Gil Medical Center in Incheon, Korea from January 1, 2014 to December 31, 2018. They were classified by age group: children (0-18 years), adults (19-59 years), or elderly (≥60 years). Event profiles, wound characteristics, and infections were compared across these age groups. Multivariable logistic regression was used to identify factors associated with wound infections. Results: Of the total 972 dog bite injuries, 272 (28.0%) were in children, 606 (62.3%) were in adults, and 94 (9.7%) were in the elderly. The median age was 30 years (interquartile range, 16-48 years) and the majority of patients (60.5%) were female. The most common place of injury was at home (73.8%) and indoors (77.0%). In children, the head and neck were the most frequent sites of injury (43%), while the most frequent site in adults and the elderly (50.8% and 59.6%, respectively) was the upper extremity. The odds ratio (OR) for wound infection was 3.997 (95% confidence interval [CI], 1.279-12.491; P=0.017) for head and neck injuries and 3.881 (95% CI, 1.488-10.122; P=0.006) for lower extremity injuries. The OR for wound infection was 4.769 (95% CI, 2.167-10.494; P<0.001) for significant injuries. Elderly patients had a higher risk for wound infection than other age groups (OR, 2.586; 95% CI, 1.221-5.475; P=0.013). Conclusions: When analyzing patients with dog bite injuries, differences across age groups were found, with the elderly at the highest risk for significant injury and wound infection. It is recommended that age-specific approaches and strategies be used to prevent dog bite wound infections.
