This study was performed to collect the basic data of DEA 1.1 in four small breed (Maltese, Shih-tzu, Poodle, Yorkshire terrier) and in three large breed (German shepherd, Labrador retriever and Jindo) dogs in the Daejeon area. 105 dogs from 7 breeds (Maltese=20, Shih-tzu=19, Poodle=15, Yorkshire terrier=11, German shepherd=10, Labrador retriever=10, Jindo=20) were selected and tested using the dog blood typing Kit$^{(R)}$ (Korea Animal Blood Bank Inc., South Korea). The prevalence of DEA 1.1 was 83%, that of DEA 1.2 was 17%, and there was no DEA (-) blood type identified in this study. Prevalence according to breeds was Maltese (DEA 1.1, 85%; DEA 1.2, 15%), Shih-tzu (DEA 1.1, 95%; DEA 1.2 5%), Yorkshire terrier (DEA 1.1, 91%; DEA 1.2, 9%), Labrador retriever (DEA 1.1, 90%; DEA 1.2, 10%). One hundred percent of DEA blood type 1.1 was discovered in all of the Poodles and German shepherds, and a higher prevalence of DEA 1.2 was found (DEA 1.1, 40%; DEA 1.2 60%) in Jindo dogs. The prevalence of DEA 1.2 in the Jindo dogs was significantly higher than in other breeds (P<0.01). German shepherds and Labrador retrievers may be more suitable as donor dogs than Jindo dogs in the Daejeon area. Larger scale studies are necessary from more dogs and other areas in South Korea.

A 4-year-old spayed female, Yorkshire terrier dog with a history of petechial and ecchymotic hemorrhages on the face, trunk and hind limb was referred to Veterinary Medical Teaching Hospital, Cheju National University. The complete blood count revealed a marked thrombocytopenia ($96{\times}10^3/{\mu}l$). The biochemical profile showed only slightly increased glucose. The coagulation profile such as prothrombin time and activated partial thromboplastin time, was within the reference range. In Giemsa staining, there were no endoparasites like as Babesia spp. on the RBC. This case was diagnosed as a idiopathic thrombocytopenia in a Yorkshire terrier dog. She was treated with prednisone (1 mg/kg BW, IM q 12 h) and cephalosporin (10 mg/kg BW, IM, q 12 h). When rechecked on day 6, the platelet was within reference range ($507{\times}10^3/{\mu}l$) and also petechial and ecchymotic hemorrhages on the body were gradually improved without any complications. The dose of prednisone was decreased to 0.5 mg/kg BW, q 24 h. On day 17, we finished treatment because all the clinical signs, blood and serum chemistry were reference range and platelet count was dramatically increased.

To study effective dossage and administration route for scaling, ketamine HCl/propionyl promazine HCl(ketamine) combination and tiletamine HCl/zolazepam HCl(zoletil) were administered in one hundred six dogs. The dogs were toy poodle, Yorkshire Terrier, Pekingese and Chihuahua. Scaling and polishing time, possible treatment time after the first injection of anesthetics, the number of anethesia added, presence of tongue movement during anesthesia, the presence of swaying sign during recovery and respiration were evaluated. The possible treatment time after the first Injection of anesthetic in toy poodle were 26.3${\pm}$3.0 minutes with intravenous(IM) treatment of ketamine 10mg/kg, and 21.4${\pm}$6.6 minutes with intramuscula(IM) treatment of zoletil 8mg/kg, In Yorkshire Terrier were 19.51: 1.7 minutes with IV treatment of ketamine 10mg/kg. 19.0${\pm}$5.2 minutes IM and 20.8${\pm}$6.1 minutes with IM treatment of zoletil 5mg/kg,24.8${\pm}$3,5 minutes with IM treatment of zoletil 8mg/kg. In pekingese were 27.5${\pm}$2.1 minutes with IM treatment of ketamine 10mg/kg,28.0${\pm}$4.2 minutes with IM treatment of zoletil 8mg/kg. In Chihuahua were 19.5${\pm}$1.9 minutes with IV treatment of ketamine 7mg/kg, 17.5${\pm}$1.7 minutes with IM treatment of ketamine 10mg/kg and 20.3${\pm}$3.8 minutes with IM treatment of zoletil 5mg/kg, 21.2${\pm}$5.5 minutes with IM treatment of zoletil 8mg/kg. Swaying sign was observed in all group during recovery time, espically, in toy poodle and Yorkshire Terrier which administered zoletil 8mg/kg IM showed more severe swaying sign. The present results suggested that injection of zoletil 8mg/kg IM might be relatively effective for scaling in Chihuahua Within 20 minutes treatment for scaling in Yorkshire Terrier and Chihuahua, IM treatment of ketamine 7 to 10mg/kg is recommended.

Ninety-nine dogs diagnosed as tracheal collapse were reviewed for 2002-2003 year at Veterinary Medical Teaching Hospital, Seoul National University with clinical records and radiographs. Dogs were ranged in age from 1 to 15 years old (average 8.23 years old) and in weight from 1.2kg to 10.3kg (average 3.3kg). The population included 58 females (6 spayed) and 41 males (8 castrated). It is highly predominant in Yorkshire terrier (64, 64.6%) followed by Pomeranian (10, 10.1 %), Poodle and Chihuahua (8, 8.1%), Maltese (4, 4.0%), mixed breed (3, 3.0%), Cocker Spaniel and Pug (1, 1.0%). The incident rate of female dogs (59%) exhibited relatively higher than that of male dogs (41%). The most prevalent occurrence location was thoracic inlet (60%) of all and carina region (15%), intrathoracic trachea (14%) and cervical trachea (11 %) showed similar rate. Conclusively, tracheal collapse was observed in completely matured or old small breed dogs, largely Yorkshire terrier, on thoracic inlet primarily regardless of gender. These tendencies were apparently similar to previous reports.

A two-month-old female Yorkshire terrier was referred to the Veterinary Teaching Hospital, College of Veterinary Medicine, Kyungpook national University. The patient was presented with a history of dyspnea, cough, exercise intolerance and abdominal distension, but she was appetence. In physical examination the puppy was coughed on slight tracheal compression. Rectal temperature, pulse and respiratory rate were normal, and grade 3/6 systolic murmur heard at the left heart base. The murmur was crescendo-decrescendo. Electrocardiography showed sinus arrhythmia, right-ventricular hypertrophy pattern, and right axis deviation. Thoracic radiography revealed cardiomegaly, bulging of the main pulmonary artery, and enlarged left side heart. Abdominal radiography revealed abdkominal distention. Echocardiography showed hypertrophy of right ventricle and turbulence in the pulmonary artery in parasternal oblique view. Subvalvular pulmonic stenosis was diagnosis based upon the clinical signs, physical examination, electrocardiography, radiography and echocardiography. We treated the patient with furosemide, enalapril and $\beta$-blocker. After the clinical signs of cough, abdominal distension and dyspnea were disappeared, she was on just $\beta$-blocker for prevention of occurrence of congestive heart failure. Now she was recovered her health, and she is not on any medication.

An 11-year-old female Yorkshire terrier presented with alopecia, hyperpigmentation, and pruritus. Dermatological examination revealed a large number of Demodex mites including D. cornei and D. canis. Mean length of total body length of D. cornei was one third shorter than that of D. canis. In addition, sequential analysis of DNA extracted from the skin lesions showed a 97% and 99% identity with the two sequences of D. canis and D. cornei. This is the first report of a combined infestation of D. cornei and D. canis in Korea, along with its morphological and molecular characterization.

Serial ultrasonographic examinations were daily performed on 8 bitches (5 Maltese and 3 Yorkshire terrier) from day 15 until parturition to determine the size of gestational structures. Gestational age was timed from the day of ovulation (day 0), which was estimated to occur when plasma progesterone concentration was first increased above 4.0 ng/ml. When the size of fetal and extra-fetal structures according to gestational age was measured, there was a difference between Maltese and Yorkshire terrier in extra-fetal structures (P<0.001), and no difference in fetal structrures (P<0.001). The correlations between the gestational age and the growth in fetal and extra-fetal structures were examined by regression analysis. The extra-fetal structure which showed high correlation from day 20 to 35 was inner chorionic cavity diameter in two breeds. The fetal structures which showed high correlation from day 36 until parturition was fetal head diameter in two breeds. In conclusions inner chorionic cavity diameter was the most accurate for estimation of gestational age and prediction of whelping day from day 20 to 35, and fetal head diameter from day 36 to parturitions respectively. Ultrasonography is very useful tool to evaluate the gestational age and to predict the whelping day in pet dogs.

A 15-year-old intact Yorkshire terrier was presented with anorexia, lethargy, and a pale mucous membrane. A physical examination one year ago revealed right testis mass and subcutaneous petechia. Blood work revealed severe thrombocytopenia and mild anemia, and no abnormalities were found in serum chemistry or ultrasonography. The preoperative serum estrogen concentration was moderately elevated. The enlarged testis was surgically removed. A well-encapsulated mass composed of polyhedral or round with abundant eosinophilic cytoplasm containing fine granular or vacuolation were found in a histological examination of the removed tissue. The nuclei of tumor cells were round, and mitotic figures were low but neoplastic cells showed a mild invasive tendency to adjacent tissues with contained neoplastic cell emboli in one lymphatic lumen. A diagnosis of a malignant Leydig cell tumor was made. The patient recovered from surgery uneventfully, but his condition worsened despite repeated transfusions and supportive therapy, and he was euthanized according to the owner's decision. Leydig cell tumor should be included in estrogen toxicity associated with testicular mass.
