Background: Cataracts are the leading cause of impaired vision or blindness in dogs. There are many antioxidants that can prevent cataract progression, but whether they are clinically effective in dogs has not been established. Objectives: To analyze the delaying or preventing effect of oral antioxidants on canine senile cataracts through retrospective analysis. Methods: Medical records of dogs from January 1, 2015 to July 10, 2020 were reviewed. Dogs that were 8 yr of age or older with senile cataracts were included in this study. The dogs were divided into two treatment groups (dogs administered with Ocu-GLO supplement and dogs administered with Meni-One Eye R/C supplement) and a control group (dogs that were not administered any supplement). Dogs with incipient and immature cataracts were included in this study. Altogether, 112 dogs (156 eyes) with incipient cataracts and 60 dogs (77 eyes) with immature cataracts were included. The period of time that cataracts progressed from incipient to immature, and from immature to mature was recorded for each dog. Results: There was no significant delaying effect on the progression of incipient cataracts. However, both Ocu-GLO (hazard ratio = 0.265, p = 0.026) and Meni-One (hazard ratio = 0.246, p = 0.005) significantly delayed the progression of immature cataracts compared to the control group. Conclusions: Although there was no significant delaying effect of oral antioxidants on incipient cataract progression, antioxidants could be used to delay the progression of senile immature cataract.

This study was carried out to investigate the actual condition of canine herpesvirus(CHV) infection in Korea. A total of 338 serum samples were collected randomly from the breeding and companion dogs in the local areas in Korea. The serum samples were used to determine the actual condition of the canine herpesvirus infection in Korea using enzyme linked immunosorbent assay(ELISA). The mean prevalence of CHV infection in dogs was 37% and that of the breeding and companion dogs was 58% and 28%, respectively. The prevalence of CHV infection in Seoul, Kyung-gi, Chung Nam, Cheon Nam and Pusan was detected 23%, 28%, 18%, 28% and 70%, respectively. The prevalence of CHV infection in less and more than 6 months old dogs, and in male and female dogs was 26% and 40%, 42% and 33%, respectively. These results indicate that the incidence of CHV infection is high in Korea, especially breeding dogs and older dogs.

Dirofilaria (D.) immitis is an important canine parasitic nematode in dogs. D. immitis parasitizes the right ventricle and pulmonary artery of dogs. An ivermectin and pyrantel pamoate compound (IPPC) was administered to dogs naturally infected with this parasite. IPPC is composed of 68.0, 136.0 and $272.0{\mu}g$ of ivermectin and 57.0, 114.0 and 227.0 mg pyrantel pamoate for small, middle, and large animals. Ivermectin has activity against nematodes and ectoparasites in dogs. Pyrantel pamoate is also effective against nematodes in dogs. Our results showed that this drug combination has good efficacy in D. immitis infected dogs.

Nine dogs with history of lameness and anorexia were presented. On physical examination, all dogs had gait abnormality and six dogs had high body temperature. Their clinical signs were mostly episodic, and only non-specific symptoms were occasionally observed. Arthrocentesis was performed in all dogs, and immune-mediated polyarthritis (IMPA) was diagnosed. Definitive rheumatoid arthritis (RA) and systemic lupus erythematous (SLE) were diagnosed in one dogs, one each. Prednisolone (PDS) was chosen as the first-line therapy for all dogs, except for the one with RA. Most cases responded to PDS but some cases including those of SLE and RA were refractory to PDS. IMPA can be challenging to diagnose due to its vague symptom and is commonly implicated in 'fever of unknown origin'. Therefore, clinicians should consider IMPA as a differential diagnosis when the patient has fever with systemic, non-specific signs, such as anorexia and depression, but does not respond to antibiotics.

This study was performed to investigate the prevalence of Toxocara canis in local districts in North West Bank of Palestine. Fecal samples from 132 dogs were collected in Nablus, Tulkarm, and Jenin cities from September 2008 to April 2009 and examined for T. canis eggs with the floating technique. The overall infection rate of toxocariasis in dogs was 36.4%. The dogs less than 6 months old showed higher infection rates than those older than 12 months (p=0.04). Vigorous interventions are necessary, such as routine coprological examinations of dogs and prescription of anthelmintics to infected dogs.

In human, sympathetic nerve blocks with local anesthetics are widely used to treat a variety of diseases in the innervating regions. However, its procedure in dogs is difficult to approach and process repeatedly because of anatomically location. Therefore, this study was designed to develop a new technique of sympathetic nerve block in beagle dogs. Fifteen healthy beagle dogs, which did not show any neurologic abnormalities and disease, were used for the study. Radiograghs were taken after injected radiopaque material mixed with 2% lidocaine at the cranial cervical ganglion and injected methylene blue using the same percutaneous technique to verify the reliability of this newly developed technique. The successful block rate of the cranial cervical ganglion block was present in 80% of all dogs and the stained cranial cervical ganglions were shown in all dogs. The results show that this new technique of the cranial cervical ganglion block is a reliable and simple method that can be used for clinical studies in dogs.

Incidence of gastrointestinal disease in dogs of Seoul and Kyung-gi area was 40.5% (380/939) and dogs with gastrointestinal disease were more likely to be 1-5 month old (55.5%). Comparison among seasons revealed that spring(48.3%) was potentially at increased risk The incidence of pancreatitis in the gastrointestinal disease was 1.49% (6/402). In helathy dogs, amylase activity was higher in male dogs than female and in the alee of >1 year than <1 year. Lipase activity was higher in female dogs than male, and higher in the age of <1 year than >1 year. The correlation coefficient$(r^{2})$ was 0.71 between the methods of measuring amylase; amyloclastic and chromogenic methods.

Recently, as the number of families raising dogs has increased, cases of lost dogs have frequently occurred. According to US statistics, 5% of the total dogs are reported to be alive, with only 18% reporting to their owners. Therefore, a device for preventing the loss of dogs is needed, and the demand for the market is rapidly growing. Therefore, it is necessary to develop a lost device for dogs. In this paper, we developed a loss prevention device that combines low-power broadband wireless communication technology, LoRa communication method, and GPS positioning technology. The result of this study is expected to prevent the loss of dogs. It is also expected that social problems will reduce the problem of lost dogs.

We describe 7 cases of splenic smooth muscle tumors in dogs. Histopathological and immunohistochemical analysis revealed that 6 cases were diagnosed as splenic leiomyosarcoma and 1 case as leiomyoma. All dogs underwent splenectomy without chemotherapy, and one of them was euthanized 2 months after surgery because of hepatic metastasis. Of the remaining 6 dogs, 5 died in the postoperative period and only one dog survived > 4 years. The median survival of the 6 dogs was 16.9 months. To the best of our knowledge, this is the first detailed study on splenic smooth muscle tumors in dogs in Korea.

[Purpose] Exercise is a fundamental way to maintain and improve health and physical fitness. Many human studies have demonstrated the beneficial effects of exercise on various biological parameters. However, studies investigating the effects of exercise in dogs are limited. This review summarized the current data from studies that examined the effects of different exercise conditions (treadmill vs. non-treadmill and acute vs. chronic) on physiological and hematological parameters in dogs. [Methods] Papers addressing the effects of exercise in dogs published from January 2000 to October 2020 were retrieved from the online databases of Scopus, Google Scholar, and PubMed and were selected and reviewed. [Results] The exercise conditions differentially affected physiological and hematological responses and adaptation in dogs. Therefore, the development and comprehensive evaluation of scientific exercise programs for dogs are necessary. [Conclusion] The dog would be a valuable exercise science animal model, and studies aiming at the optimal health, well-being, and quality of life of dogs need to be conducted.
