A 9-month-old neutered male German Shepherd dog was referred with the primary complaint of episodic collapse. Apparent abnormal findings were not observed in physical examination, routine biochemistry, and diagnostic imaging studies. In the 12-lead surface ECG after collapse, the dog showed frequent ventricular premature contractions (VPCs) with torsade de pointes. The frequency of VPCs was reduced after lidocaine infusion. Based on the history, findings in event recordings oi the ECG and lidocaine response test, the dog was diagnosed as inherited malignant ventricular tachyarrhythmia. Although the dog was initially responded to oral sotalol therapy, the dog was died suddenly. This report described the first case of malignant ventricular tachyarrhythmia of German Sheperd in Korea.

A 6-year-old castrated male Miniature Pinscher dog was referred due to shaking, panting and inappropriate elimination during thunderstorms. The dog had noise phobia after a car accident two years ago. The intensity of the fear of noise, especially with thunderstorms, worsened during the past 3 months (thunderstorm season). Physical examination revealed hyperthermia, tachypnea (panting), mild tachycardia, and an elevated systolic blood pressure. Laboratory examination revealed mild polycythemia with a lower oxygen pressure and saturation. Based on the history, physical examination, and laboratory tests, the dog was diagnosed as a noise phobia concurrent with relative polycythemia. Treatment was initiated with behavior modification with desensitization, counter-conditioning, and medication. Music therapy was also used and appeared to be beneficial. Clinical signs including polycythemia are improved. This case indicates that relative polycythemia can be occurred by chronic mental stress, such as noise phobia in a dog.

The purpose of this study is to understand dogs for their happy lives. Experiment and survey were conducted to find out the effects of sensory stimulation on dogs emotions. Sensory were divided into visual, auditory, olfactory, tactile, complex and emotions were measured by the rate of deep sleep, feed intake, and heart rate. Research has shown that complex stimulation (walking) is the most positive stimulation for dog's emotions, but visual stimulation and auditory stimulation do not act as stimuli that positively change usual state of dog's emotions. Olfactory stimuli is the second best stimulation. Since olfactory stimulation is effective in maintaining a calm state without large deviation in the dog's state, it can be used as a method for relieving the dog's stress in exceptional situations when complex stimulation is not possible. On the other hand, tactile stimulation, bath, is a negative sensory stimulus that causes hypersomnia and binge eating for most dogs.

A five-year-old, male, Great Dane weighing 107 kg was presented with anorexia, abdominal distension, and dyspnea for 5 days. Physical examination, blood works, radiography, electrocardiography (ECG), and echocardiography were performed. Based on severely low fractional shortening (FS) and marked four chamber enlargement in echocardiography, continuous atrial fibrillation and occasional ventricular premature complex (VPC) on ECG, the dog was diagnosed as dilated cardiomyopathy (DCM) concurrent with congestive heart failure. Pleural effusion and ascites were modified transudate. In accordance with DCM scoring system recommended by European Society of Veterinary Cardiology (ESVC), DCM score was 13/15 in this case. Concentrations of cTnI and NT-pro-BNP were 1.0 ng/mL and 693 pmol/L, respectively. Since the former and the latter were remarkably high values, it was certain that the patient had grave prognosis. Intensive care was performed for the dog and the clinical signs as well as the radiographic abnormalities were resolved. However, when he presented serious dyspnea again at 25 days post therapy, the dog was dead. In case of canine DCM, the scoring system for the diagnosis and cardiac biomarkers including NT-pro-BNP and cTnI could be useful to advise owners on the status and prognosis of their dog with DCM.

This study was aimed to know the effect of cadmium chloride (CdCl₂) on glucose transport in L6 myotube and its action mechanism. CdCl₂ increased the 2-deoxy- (l-3H)-D-glucose (2-DOG) uptake 1.9 and 2.4 fold at 10 and 25 μM respectively. To investigate the stimulating-mechanism of glucose transport induced by CdCl₂, the wortmannin and PD98059 were used as PI3K (phosphatidylinositol 3-kinase) inhibitor and MAPK inhibitor respectively, which did not affect 2-DOG uptake. This fact suggests that CdCl₂ induced 2-DOG uptake may not be concerned to the insulin signalling pathway. Whereas nifedipine, a calcium channel blocker, and trifluoperazine, a calmodulin inhibitor, were found to inhibit the 2-DOG uptake stimulted by CdCl₂. In addition, we also measured the ROS (reactive oxygen species) production and GSH level in L6 myotube to investigate the correlation between the glucose uptake and ROS. CdCl₂(25 μM) increased ROS generation approximately 1.5 fold and changed the cellular GSH level, but GSSG/GSH ratio remained unchanged. CdCl₂ stimulated 2-DOG uptake and ROS generation were inhibited by N-acetylcystein. And BSO pretreatment, a potent inhibitor of γ-GCS, resulted in the dramatic decrease of 2-DOG uptake and also the increase of the sensitivity to cadmium cytotoxicity. The obtained results suggest that CdCl₂-stimulated glucose uptake might be based on the activation of HMP shunt as an antioxidant defense mechanism of the cells.

A 6-year-old, castrated male Shih-tzu dog was presented due to left side facial paralysis with head tilt. Neurological examination revealed absence of facial sensation, menance response, and palpebral reflex on the left side. On magnetic resonance imaging (MRI), intracranial intra-arachnoid cyst (IIAC) was noted. The dog was poor response to steroid and dieuretic therapy. Based on characteristic historical and clinical findings, and excluding of other causes of acute facial nerve dysfunction, the dog was tentatively diagnosed as idiopathic facial paralysis. The clinical signs were improved gradually after acupuncture therapy with bee venom. Eight weeks after initial acupuncture with bee venom, the patient recovered sensory and neurological facial signs. This case report demonstrates that bee venom acupuncture for an idiopathic facial paralysis could be useful in a dog.

The cumulative registration status of dogs is from 1.07 million in 2016 to 2.32 million in 2020. Animal registration is increasing by more than 10% every year, and accordingly, a name must be decided when registering a dog. We want to give a name that fits the characteristics of a dog's appearance, but there are many difficulties in naming it. This paper explains the development of a system for recognizing dog images and recommends dog names based on similar objects or food. This system extracts similarities with dogs' images through models that learn images of various objects and foods, and recommends dog names based on similarities. In addition, by recommending additional related words based on the image data of the result value, it was possible to provide users with various options, increase convenience, and increase interest and fun. Through this system, it is expected that users will be able to solve their concerns about naming their dogs, check names that suit their dogs comfortably, and give them various options through various recommended names to increase satisfaction.
