Rabies virus is transmitted most commonly through a bite from an infected dog. Especially, stray dogs that are not excluded from contact with rabid wild animals can become rabies vectors. Therefore, serological survey of rabies virus from stray dogs in Seoul Metropolitan City was carried out in this study. To investigate prevalence of rabies antibodies in the stray dogs, serum samples were taken from 500 stray dogs between April and December 2010. Antibodies to rabies virus were detected by indirect ELISA. Of 500 tested sera, 147 (29.4%) were positive to rabies virus. Prevalence rates of rabies antibodies(PRRA) in northern and southern Han river region of Seoul were 26.4% and 33.2% respectively. PRRA in male and female dogs were 33.6% and 26.1% respectively. PRRA in less than 1 year, 1~2< years, 2~3< years, 3~5< years, 5~10< years and over 10 years old dogs were 12.7%, 21.6%, 26.4%, 36.4%, 32.5% and 46.4%, respectively. These results indicates that antibody seroprevalence to rabies is still not enough to prevent rabies and rabies vaccination is required to enhance the seroprevalence in the dogs. To improve the situation, measures to raise public awareness of rabies and its prevention is needed. Also, reducing stray dogs and keeping companion animals from contact with wild animals are indispensable for the prevention of rabies.

Cystatin C is a low molecular weight 13 kilodalton protein. It is known to be a more sensitive marker of glomerular filtration rate than creatinine in humans. The purpose of the present study was to demonstrate the changes of renal markers including cystatin C according to the severity of chronic mitral valve insufficiency (CMVI) and to investigate the clinical relevance of cystatin C as an early renal marker in dogs with CMVI. A retrospective study was performed to assess renal function according to International Small Animal Cardiac Health Council (ISACHC) system classification of heart failure in dogs with CMVI. Thirty seven dogs were divided into a group 1 (healthy dogs ; n = 10), a group 2 (ISACHC I ; n = 10) and a group 3 (ISACHC II-III ; n = 17). In all dogs, serum concentrations of bun (sUr), creatinine (sCr) and cystatin C (sCys-C) were measured with an automated analyzer. In dogs with CMVI, sCys-C concentrations were significantly correlated with sCr concentrations and were independent of age, BW, SBP, and sex. Renal dysfunction tended to occur more frequently as the severity of CMVI increases. In dogs with mild CMVI, only sCys-C concentrations were statistically higher than in healthy dogs. This study demonstrates the clinical relevance of sCys-C. sCys-C may be a valuable renal marker for early diagnosis of renal dysfunction in dogs with CMVI.

In canine acute pancreatitis (AP), inappropriate release and activation of zymogen proteases within the pancreas results in the consumption of serum antiproteases. The aim of this study was to examine whether the serum concentrations of ${\alpha}_2$-macroglobulin (A2MG), ${\alpha}_1$-antitrypsin (A1AT), and C-reactive protein (CRP) differ between dogs with AP and healthy dogs. Twenty healthy dogs and 20 dogs with AP were included in this study. Concentrations of A2MG, A1AT, and CRP were measured in the sera of healthy dogs and dogs diagnosed with AP. Serum A2MG and A1AT concentrations were significantly lower in dogs with AP than in healthy dogs, whereas the serum CRP concentration was significantly higher. In addition, the concentrations of A2MG and A1AT were significantly higher in AP survivors than in AP non-survivors, while the CRP concentration was significantly lower. However, in both AP survivors and non-survivors, the CRP concentrations showed a negative correlation with A2MG concentrations but not with A1AT. These findings indicate that serum antiproteases and CRP concentrations might be associated with the mortality rate of AP in dogs.

Background: Stenting is an effective treatment option for tracheal collapse in dogs. Cross-braided tracheal stents are currently the norm in veterinary medicine, but cross-and-hook braided stents have recently been adopted in human medicine. We examined whether stents manufactured using this novel braiding technique provided additional advantages for the treatment of tracheal collapse in dogs. Objectives: To evaluate the outcomes of cross-and-hook braided stent implantation in the treatment of tracheal collapse in dogs. Methods: The medical records of 22 client-owned dogs that underwent luminal placement of cross-and-hook braided Fauna Stents for the treatment of tracheal collapse between January 2018 and July 2021 were examined and data on canine signalment, clinical signs, diagnostic test results, surgical outcomes, and postoperative complications were retrieved and analyzed statistically. Results: Twenty-six stents were surgically implanted, with 20 dogs (90.9%) receiving one stent and the remaining two (9.1%) receiving two or more stents. All dogs survived the procedure. The median survival time at a median follow-up of 990 days was 879 days. At the final follow-up examination, loss or mild improvement of cough was observed in all dogs. Conclusions: Compared with conventional lumen stents, the cross-and-hook braided Fauna Stent offered a higher survival rate and improved clinical symptoms in all patients. The results of this study suggest that the Fauna Stent may be a promising treatment option for dogs with tracheal collapse.

The purpose of this study was to investigate the effects of desensitization and flooding on the behavior of dogs during grooming, focusing on their response to the sound and skin stimulation while using a clipper. A total of 20 adult dogs over two years of age with complete personality formation were included in the study. Ten dogs, of which three were Bichons (average weight 5 kg), four were Poodles (average weight 5 kg), and three were Malteses (average weight 4 kg), were subjected to the desensitization process. The remaining 10 adult dogs were subjected to the flooding experiment, and were of the same breed and average weight as the adult dogs used in the desensitization process. The desensitization and the flooding were performed three times a day (approximately 1 min per session) for 10 days. For desensitization, statistical significance was observed only on the fifth day, when compared by breed (p<0.05). Overall, when compared by measurement day, the results of desensitization for Bichon, Poodle and Maltese dogs were statistically significant (p<0.05). The results for the Bichon, Poodle, and Maltese dogs that were subjected to flooding were found to be statistically significant (p<0.05). There was a significant difference in the results of the flooding on the second and ninth days (p<0.05); however, flooding had no effect on the other days (p>0.05). Desensitization using the clipper, a beauty tool, was faster than flooding in achieving stabilization. In conclusion, desensitization and flooding showed positive results on the stress relief and emotions of dogs during grooming, with respect to cosmetic fear response.

Cancer is a major cause of death in dogs worldwide, and the incidence of cancer in dogs is increasing. The attenuated total reflection Fourier transform infrared spectroscopic (ATR-FTIR) technique is a powerful tool for the diagnosis of several diseases. This method enables samples to be examined directly without pre-preparation. In this study, we evaluated the diagnostic value of ATR-FTIR for the detection of cancer in dogs. Cancer-bearing dogs (n = 30) diagnosed by pathologists and clinically healthy dogs (n = 40) were enrolled in this study. Peripheral blood was collected for clinicopathological diagnosis. ATR-FTIR spectra were acquired, and principal component analysis was performed on the full wave number spectra (4,000-650 cm^-1). The leave-one-out cross validation technique and partial least squares regression analysis were used to predict normal and cancer spectra. Red blood cell counts, hemoglobin levels and white blood cell counts were significantly lower in cancer-bearing dogs than in clinically healthy dogs (p < 0.01, p < 0.01 and p = 0.03, respectively). ATR-FTIR spectra showed significant differences between the clinically healthy and cancer-bearing groups. This finding demonstrates that ATR-FTIR can be applied as a screening technique to distinguish between cancer-bearing dogs and healthy dogs.

Two dogs with spontaneously developing osteosarcoma of the extremities and one dogs with spontaneously developing osteosarcoma of the mandible were referred to the University of Tokyo Veterinary Medical Center. Three dogs were diagnosed as osteosarcoma by clinical sign, radiography, and histological examination. After diagnosis, two dogs was treated by amputation and one dog by partial mandibulectomy. Three weeks after two surgery, all dogs administered cisdiamminedichloroplatinum (cisplatin) chemotherapy 40-50 mg/$m^2$, IV of body surface. After cisplatin therapy, dog 1 and dog 3 survived without overt metastasis. Dog 2 died of metastatic disease. The survival times of dog 1, dog 2, and dog 3 were estimated to be 69.5, 36.3 and 66.4 weeks, respectively. It was thought that the surgery in combination with cisplatin chemotherapy was a useful method to treat a canine osteosarocoma.

In recent years, worldwide surveys of Toxoplasma gondii infection in dogs have been reported. However, only limited surveys of T. gondii infection in police dogs have been available, including China. In the present study, we report the seroprevalence of T. gondii in police dogs in Shenyang, northeastern China. Sera from 291 police dogs were examined for T. gondii antibodies with the modified agglutination test (MAT), and 30.9% animals were tested seropositive. The results of the present study indicated a relatively high prevalence of T. gondii infection in police dogs in Shenyang, China.

The objective of this study was to determine the safety test for propolis in Beagle based on blood count, serum biochemistry, and electrolyte. Total six beagle dogs were assigned to this experiment. To investigate the safety of propolis in beagle dogs, we performed oral administration of propolis (5%) for 8 weeks. Among six beagles, three beagle dogs were randomly allocated to the control group which were fed only regular fodder, and the other three dogs were assigned as the treatment group which were fed regular fodder and propolis (5%). No clinical signs were observed in neither group throughout the experimental period. During the experimental period, there were no significant change in feed intake, water consumption, and body condition. Also, there were no statistically significant differences in hematological and biochemical analyses between the control group and the treated group. Our safety study showed that oral consumption of propolis did not cause any toxicological effects in beagle dogs.

Fifty six dogs diagnosed with intervertebral disk disease between January 1999 and August 2001 were reviewed to characterize signalments and prognosis. Seventy-five percent was chondrodystrophoid breeds (42 dogs). Mean age was 5.1$\pm$3.0 year-old and fifty-four percent had acute onset. Interspaces between eleventh thoracic vertebrae and fourth lumbar vertebrae were affected most commonly. Success rate of conservative treatment to dogs with paresis was 83% and that of operation to dogs with paralysis was 67%. Six dogs were recurred and 50% of them had recovered again. There was significant correlation between success rate of treatment and the degree of clinical signs but there was no significant correlation between success rate of treatment and rate of onset, status of clinical signs, duration of clinical signs.
