Thromboembolic complications are increasing in veterinary medicine. Thromboelastography (TEG) is a more comprehensive method for assessing the clotting process than standard plasma-based coagulation tests. This study compared the ability of TEG and standard coagulation tests to analyze the overall hemostatic state of dogs. The study involved 40 dogs with underlying diseases that predispose to hypercoagulability, including neoplasia, hyperadrenocorticism, immune-mediated diseases, gastrointestinal diseases, and protein-losing nephropathies and enteropathies, and 20 healthy dogs. Their overall hemostatic functional state was evaluated by TEG and routine coagulation assays, including activated partial thromboplastin time, prothrombin time, platelet count, and D-dimer concentration. TEG analysis showed significant differences in clot formation time, ${\alpha}$ angle, and maximum amplitude (MA) between diseased and control dogs (P < 0.001 each). Increased MA was the most frequent abnormality on TEG and was indicative of hypercoagulability. TEG was useful in detecting hemostatic dysfunction in dogs with diseases associated with hypercoagulability. Dogs with TEG tracings indicative of hypercoagulability are likely to be in procoagulant states. Future prospective studies are needed to evaluate whether TEG tracings indicative of hypercoagulability are predictive of thrombosis in dogs.

Background: Oral neoplasia has been reported to account for 6-7% of all canine cancer and 3% of all feline cancers. To the authors' knowledge the last epidemiologic analysis of general oral cancer in dogs and cats was published in 1976. Objectives: The goal of this study was to report contemporary demographic information regarding oral tumors in dogs and cats. Methods: Information was collected from cats or dogs diagnosed with oral neoplasia from the Veterinary Medical Data Base. Medical records representing cases that presented to one of 26 veterinary teaching hospitals from January 1, 1996 through December 31, 2017 were included. Results: A total of 1,810 dogs and 443 cats were identified. A total of 962 cases (53.6%) of canine oral tumors were classified as malignant and 455 cases as benign (25.4%). The majority of feline oral tumors were classified as malignant (257 cases, 58.1%) and only a few benign (11 cases, 2.5%). The incidence of oral tumors was calculated to be 4.9 per 1,000 dogs (0.5%) and 4.9 per 1,000 cats (0.5%). Conclusions: This incidence of oral tumors is considerably higher than previously reported in both dogs and cats. These results provide valuable information for generation of hypotheses for future investigations of breed-based and pathology-based oral neoplastic studies.

This study aimed to evaluate the effects of four types of environmental enrichment on the improvement of companion dogs' behavioral problems due to separation anxiety. A total of 21 dogs of various breeds were included in the study. Data were collected to investigate the behaviors associated with anxiety in dogs, including vocalization, elimination, escape attempts, and destructiveness. A first stage, in which the dog and owner were together (P0), lasted 15 min, and a second stage, in which the dog and owner were separated (P1), lasted 15 min. After the dog and owner were separated (P1), the third stage (P2), during which the environment was enriched, lasted 20 min, and the fourth stage, following environment enrichment (P3), lasted 15 min. The results of the study indicated that compared to P0, the frequency of problematic behavior was highest during the 15 min following separation from the owner (P1). Following environmental enrichment, the average frequency of problematic behaviors in P2 decreased (P < 0.001) compared to P1. Environmental enrichment can also be used appropriately in the case of companion dogs, including shelter dogs or experimental dogs that use a limited kennel, and is a particularly effective means of improving the quality of life of dogs.

Background: In veterinary medicine, previous studies regarding the diagnostic performance of shear wave elastography (SWE) in chronic kidney disease (CKD) are not consistent with each other. Moreover, there has been no study evaluating the relationship between symmetric dimethylarginine (SDMA) concentration and renal shear wave velocity (SWV) using two-dimensional SWE (2D SWE) in dogs with CKD. Objectives: This study aimed to evaluate the diagnostic capability of 2D SWE in dogs with CKD and to assess the relationship between renal SWV and SDMA concentration. Methods: Dogs with healthy kidneys and dogs with CKD underwent 2D SWE and SDMA assay. Renal stiffness was estimated as renal SWV in m/s. Results: SDMA concentration had a weak positive correlation with the left (r = 0.338, p = 0.022) and right renal SWV (r = 0.337, p = 0.044). Renal SWV was not significantly different between healthy kidney and CKD groups in the left (p = 0.085) and right (p = 0.171) kidneys. Conclusions: 2D SWE may could not distinguish between dogs with healthy kidney and dogs with early stage of CKD, but it would be useful for assessing the serial change of renal function in dogs.

The incidence of canine cognitive dysfunction syndrome (CCDS), a prominent geriatric disease, is increasing because of the extended lifespan of companion animals. Various complementary therapies have been proposed for the management of CCDS. This study evaluated the clinical efficacy of the Brain Six Complex Extract^ⓒ in dogs with cognitive dysfunction syndrome (CDS). Fifteen dogs with CDS were included, and four to five drops of Brain Six Complex Extract^ⓒ, composed of herbal extracts, were applied around the dorsal neck of all dogs twice daily for 1-3 months. Clinical efficacy was evaluated using the CCDS scale, and serum β-amyloid oligomer concentrations were measured before and after administration of the extract. The CCDS scale score significantly decreased after administration in dogs with CDS (p = 0.0313), compared to pre-administration levels. Although the serum β-amyloid oligomer concentration decreased after administration, the change was not statistically significant (p > 0.05). A notable decrease was observed between pre- and post-administration in dogs with β-amyloid levels >300 pg/mL (p = 0.0313). The laboratory results showed no remarkable adverse effects of the extract. This study suggests that Brain Six Complex Extract^ⓒ extract could be an adjunctive treatment for dogs with CDS.

Wild raccoon dogs (Nyctereutes procyonoides koreensis) may play a role transmitting several pathogens to humans and pet animals. Information concerning the incidence of rabies, canine distemper virus (CDV), canine parvovirus (CPV), canine adenovirus type 2 (CAdV-2), canine parainfluenza virus type 5 (CPIV-5), and canine herpesvirus (CHV) is needed in wild raccoon dogs. In total, 62 brain samples of raccoon dogs were examined for rabies virus (RABV) and CDV, and 49 lung samples were screened for CDV, CAdV-2, CPIV-5, and CHV. No RABV, CAdV-2, CPIV-5, or CHV was identified, but nine CDV antigens (8.1%, 9/111) were detected. Moreover, 174 serum samples from wild raccoon dogs were screened for antibodies against the five major viral pathogens. The overall sero-surveillance against CDV, CPV, CAdV-2, CPIV-5, and CHV in wild raccoon dogs was 60.3%, 52.9%, 59.8%, 23.6%, and 10.3%, respectively. Comparisons of the sero-surveillance of the five pathogens showed that raccoon dogs of Gyeonggi province have slightly higher sero-positive rates against CDV, CPV, and CHV than those of Gangwon province. These results indicate high incidences of CDV, CPV, and CAdV-2 in wild raccoon dogs of two Korean provinces and a latent risk of pathogen transmission to companion and domestic animals.

Canine vector-borne diseases (CVBDs) are transmitted by different groups of hematophagous arthropod vectors that are distributed worldwide and can cause significant health problems for dogs. The aim of this study was to investigate and compare the prevalence of selected CVBD pathogens in rural outdoor dogs based on prevention status. Between June 2017 and February 2019, blood samples were collected from 343 clinically healthy rural dogs composing two different groups: systematically managed dogs (SMD; n=92) and personally managed dogs (PMD; n=251). Vaccination and preventive medications were applied strictly following the programmed schedule for the SMD group; in contrast, in the PMD group, they were applied only when requested by the dog owners. Serological and molecular assessments showed that significantly more dogs in the PMD group were infected with B. gibsoni (P<0.001) and D. immitis (P=0.001) than those in the SMD group. These findings suggest that the regular use of preventive medications and environmental controlling efforts contribute to reducing the prevalence of CVBD pathogen infections. In addition, dogs infected with certain kinds of CVBD pathogens could remain asymptomatic, suggesting that continuous monitoring and periodic preventive treatment should be conducted even for clinically healthy dogs.

Serum proteins of Korean native dogs (Gyeongju DongGyeong dogs) was analyzed by capillary electrophoresis system. Electrophoretic patterns showed six fractions. Total serum protein and ratio of albumin to globulin were $5.99{\pm}0.83$ (g/dl) and $1.41{\pm}0.29$ (g/dl) in DongGyeong dogs. Relative percentages of total serum albumin and $\alpha-1$, $\alpha-2$, $\beta-1$, $\beta-2$, $\gamma$-globulin fraction were $57.94{\pm}5.43$, $3.15{\pm}2.30$, $7.49{\pm}4.09$, $9.43{\pm}3.50$, $7.63{\pm}5.70$, and $14.36{\pm}7.63$, respectively. It was observed that $\beta$-globulin was higher than other fractions. The most striking alternation with age was founded in the $\gamma$-fractions. Also, it was observed that ratios of albumin to globulin in DongGyeong dogs were higher than on other dogs.

Animals imported from abroad are a cause of rabies outbreaks in many countries. Therefore, rabies serology testing for dogs and cats traveling abroad is an important measure to reduce the incidence of rabies. Rabies virus antibodies were measured in sera collected from 2,367 dogs and 894 cats between 2017 and 2021. A serum sample with a value of 0.5 IU/mL or higher was considered a pass. The overall pass rates for rabies virus were 96.4% in dogs and 98.4% in cats. The mean rabies virus neutralization assay titers were higher in cats than in dogs and in female than in male animals. According to age, 6-year-old dogs and 9-year-old cats had the highest virus neutralization assay titers. Of the failure cases, 53.0% (53/100) were dogs or cats less than 1 year old. Although the average failure rates in dogs and cats were low at 3.5% and 1.6%, respectively, the factors influencing failure were age and vaccine manufacturer. Therefore, it is necessary to observe the vaccination interval and timing of blood collection after boosting.
