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.

Neospora caninum is an important cause of abortion in dairy cattle worldwide. Dog is the definitive host for N. caninum and can infect dairy cattle. The aim of this study is to determine the prevalence of Neospora oocysts in feces of dogs from dairy farms. A total of 174 fecal samples was collected from 89 farm dogs and 85 household dogs during 2006 and 2008. Fecal samples of dogs were microscopically examined for detecting Hammondia Neospora-like oocysts (HNLO) by Mini $Parasep^{(R)}SF$ fecal parasite concentrator. HNLO were microscopically detected in 4 fecal samples (2.2%). The fecal samples with HNLO were examined by N. caninum-specific PCR. Two of the samples were positive for N. caninum. The 2 positive fecal samples were selected for inoculation to calves. Two inoculated calves were seronegative by ELISA for 4 months post-infection. This is the first report of finding N. caninum DNA in feces of farm dogs in Mashhad area, Iran.

The intestines and hearts of dogs were examined for Toxocara canis, Toxascaris leonina, and Dirofilaria immitis, after necropsy between June 26 and September 29, 2004 in Chuncheon, Korea. Of the 662 dogs examined, 6 were infected with T. canis $(0.9\%),\;86\;with\;T.\;leonina\;(13.0\%)$. Fifty dogs were infected with D. immitis among 500 dogs examined $(10.0\%)$. Five were co-infected with T. canis and T. leonina, and three were co-infected with T. leonina and D. immitis. The cumulative positive infection rate for three species was $134/662(20.2\%)$. Considering previously reported seropositive rates of T. canis excretory-secretory antigen, i.e., $5\%$ in the adult population in Korea, the possibility of toxocariasis caused by T. leonina should be reevaluated.

In this study, occurrence of canine brucellosis was surveyed in kennels, indoor dogs and stray dogs in Korea, and infrequent restriction site-polymerase chain reaction (IRS-PCR) was applied to analyze DNA polymorphism of Brucella canis (B. canis) isolates. Among a total of 501 dogs tested, B. canis antibodies by both rapid screening agglutination with 2-mercaptoethanol (2-ME RSAT) and immunochromatographic assay were detected in only 14.1% of kennel dogs. There were no seropositive cases in indoor dogs and stray dogs. DNA polymorphism was observed in 16 B. canis isolates by the IRS-PCR. Sixteen isolates were tested with primers, PsalA, PsalC, PsalG and PsalT, and different primers produced different DNA patterns. In regard to the IRS-PCR pattern of 16 isolates, 9 (56.3%) belonged to the IRS-PCR type I. The remaining 7 were differentiated as type II, III and IV. An application of the primer PsalC provided discrimination between B. canis isolated in 2005 and others.

Observations were made on the infection rate of common internal parasites in Jindo dogs from January to March, 1989. Fecal samples were collected from 115 Jindo dogs in Jindo area. On the basis of egg counting, the following results were obtained； 1. Of 115 fecal samples, 65.2％ were appeared as positive, Dogs from intensive dog-rearing places have lower infection rates than others. 2. Of the parasites detected, Toxocara canis was the most commonly encountered (26.1%). 3. Ascarids, flukes and coccidia were more prevalent in pups than in mature dogs, whereas hookworms were detected less often in young dogs than in older ones.

Eight dogs were experimentally infected with Sarcocystis by oral inoculation of cardiac muscle from naturally infected cattle. The infected dogs commenced discharging of sporocysts in the feces after 10 to 12 days of inoculation, and continued until 20 and 35 days after inoculation. Three dogs were reinfected with cardiac muscle from the naturally infected cattle. Sporocysts reappeared in the feces on 12 to 13 days after reinfection. Sarcosystis sporocysts collected from the experimentally infected dogs were fed to each of the two 30-day-old Korean native calves. The infected calves remained clinically normal, except for the high fever (${\geq}{\;} 40^{\circ}C$) and decreased hematocrit values on day 30 to 40 post inoculation. Muscular cysts of Sarcocystis were found from infected calves on day 40 post inoculation. Proliferative forms of Sarcocystis were also observed in the muscle of infected calves. These results suggest that the Sarcocystis cruzi found in Korean native cattle has a 2-host life cycle with dogs as the definitive host and Korean native calves as the intermediate host.

This study was carried out to investigate the prevalence of antibody against Toxoplasma gondii in the dog by Latex agglutination test and Indirect fluorescent antibody test. Two month-old dogs were infected intraperitoneally with T gondii to observe histopathological and immunohisto-chemical changes. Results obtained through this experiment were summarized as follows ; 1. Among the serum samples of 163 heads of the dog, 10 samples(6.1%) were positive. 2. In the sex, 6 heads (7.1%) out of 84 female dogs and 4 heads(5.1%) out of 79 male dogs were positive. However, there were no significant differences between the male and female. 3. Overall proportion of agreement between indirect fluorescent antibody and Latex agglutination test in 163 sera of dogs was 97.5%. 4. When 2 month-old dogs were infected intraperitoneally with T gondii, main clinical signs were intermittent fever, dyspnea, diarrhea. In general, the infected dogs recovered closely on the 11th day of post-inoculation. 5. At necropsy, petechial and ecchymotic hemorrages and swelling in small intestine, lung, spleen, liver and kidney were observed. 6. In histopathological observation, interstitial pneumonia, hyperemia and hemorrhages in lung were observed. Focal necrosis of hepatocytes, the neutrophil and basophil in the renal tubular epithelium were observed. 7. By immunohistochemical staining using Vectorstain ABC kit, the positive cells were recognized in the lung and the liver. 8. By indirect fluorescent antibody test, the Toxoplasma antibodies in the infected dogs were detected on the 15th day of postinoculation.

The environmental pollution by heavy metals has become a significant hygenic problem. Recently it is said the garlic supplementation in diet have protective effect on the heavy metal accumulation in tissue of rat by a researcher. In this study two experiments were undertaken. Firstly, dogs were fed diet supplemented with cadmium of cadmium plus 7% of raw garlic for 50 days. on the 50th day of experiment all dogs were euthanasied and the cadmium content of various tissue were measured by atomic absorption spectrophotometeric method. Secondly, in order to find out the toxic effect of garlic dogs were fed diet supplemented with 7% of raw garlic for 50 days and hematological or hematochemical observations were undertaken at 10 day intervals. The results obtained from these experiments were summarized as follows; 1. In dogs treated with cadmium and cadmium plus garlic cadmium was accumulated in renal cortex, liver, and muscle. However the concentrations of cadmium showed no significant between the two group. 2. In dogs fed diets supplemented with 7% of raw garlic significant decrease of erythrocyte count, packed cell volume and hemoglobin content and significant increase of Heinz body erythrocyte and reticulocyte count were recognized. 3. The garlic-treated dogs and control dogs had normal asparate aminotransferase, alanine aminotransferase, alkaline phosphotase, blood urea nitrogen value. The value showed no significant difference between the two group. 4. From these results it may be concluded that the garlic have protective effect for cadmium accmulation in tissue and excess garlic in diet could induce hemolytic anemia in dogs.

The recent increase in the number of dogs in high-density urban environments causes conflicts between dog owners and non-dog owners and the access of dogs to urban parks has been controversial among park users. A lack of exercise and socialization, however, can cause canine behavior problems such as aggression and hyperactivity which are potential dangers to people and there has increased demand for a place where people and their dogs can interact and exercise together. In many developed countries, off-leash recreation areas (OLRA) are considered as safe and effective places that dogs can exercise, play, and socialize with other dogs while reducing conflicts between dog owners and other park users. This study aimed to review the issue of dogs' access to public parks and to examine the perception of park users on OLRA to provide insights and guidelines in establishing OLRA in Korea. The survey respondents, even non-dog owners, perceived that it is necessary to provide a separate space for dogs from other park users by providing OLRAs in urban parks and showed the willingness to use. Most of dog owners consider their dogs as companions or family members and feel the lack of places to exercise their dogs. As local government plays a major role in urban animal management which emerge as a social issue at present, more active interventions of municipalities are necessary to support various needs and activities of park users. An experimental OLRAs based on community participations would be a meaningful starting point to effective urban animal management.
