The aim of this study was to compare the appearance rate of vaginal cytology during estrous cycle in small pet bitches. A characteristic features of vaginal cytology during the estrous cycle were the high proportion of superficial cell in proestrus, anuclear cell in estrus, small intermediate cell in diestrus, and small intermediate cell in anestrus, respectively. There were no statistically significant differences of appearance rate of vaginal cytology among small pet bitches in the each phase of estrous cycle. These results indicated that the vaginal cytology was useful method for estimating estrous cycle and optimal breeding time in small pet bitches.

The purpose of this study is to develop the most appropriate garment patterns for dog. This study is analyzed the body structures and bodily movements of different types of dogs and constructed garment patterns that are appropriate for each category: the basic pattern for dogs with oval-shaped chests; and the modified pattern for the ones with barrel-shaped chests. Analyzing some of the existing patterns in the market as well as studying the size chart of one of the dog apparel manufacturers, who participated in the Fashion Week for the very first time, were undertaken in order to understand the bodily figures and movements of dogs. Furthermore, based the previous studies and relevant information available regarding some of the most popular dogs in four selected countries: (names of the selected countries), dogs were broadly categorized into three groups according to the shape of their chests: Oval, Barrel, and Flat-sided. Later, two types of pattern were created and then constructed for fitting: the basic pattern for oval-shaped chest; and the modified pattern for barrel-shaped chest. As a result, the two patterns turned out to be most suitable for pet dogs.

This study was carried out the normal serial ultrasonographic appearance of the postpartum uterine involution with small pet bitches. Postpartum changes in uterine shape, architecture, echogenicity and diameter were monitored with ultrasonography in small pet bitches (Miniature Schnauzer, Cocker Spaniel and Shih-tzu). In the Miniature Schnauzer bitches, uterine diameter of the placental sites and interplacental sites were decreased from at 1 day to at 7 day, and at 1 day to at 7 day postpartum. In the Cocker Spaniel, the placental sites and interplacental sites were decreased from at 1 day to at 7 day, and at 1 day to at 7 day postpartum. In the Shih-tzu, the placental sites and interplacental sites were decreased from at 1 day to at 7 day, and at 1 day to at 7 day postpartum. And uterine diameter was no statistically significant difference among bitches (p>0.05). At 67 days, the uterine diameter in Miniature Schnauzer bitches were 6~7 mm both placental and interplacental sites, and the uterine horns showed uniform hypoechoic, tubular structures without enlargement. In present study, the involution of the uterus was completed at 67 days after parturition in Miniature Schnauzer, and 65 days in Cocker Spaniel and the Shih-tzu. There were no significant differences of normal postpartum uterine involution between small pet bitches (p>0.05). In conclusion, the postpartum involution of small pet bitches appeared to be completed normally at 65~67 days after parturition and could be identified by gross findings such as vaginal discharges and ultrasonographic findings of uterine shape and echogenicity.

Serial ultrasonographic examinations were performed to establish a prediction table of parturition date in pregnant Maltese, Yorkshire Terrier, Shih-tzu and Miniature Schnauzer bitches. The inner chorionic cavity diameter and fetal head diameter in 45 pregnant bitches were converted retrospectively based on the day of parturition. The data of inner chorionic cavity diameter obtained from Day-44 to Day-25 and fetal head diameter obtained from Day-25 to Day-1 were used to compile a equations of prediction of parturition date. The 70 pregnant bitches with unknown mating time were examined to assess an accuracy of the equations established in this study. And these results were applied to the prediction of parturition date and compared to actual parturition date. The accuracy for parturition date within 0, 1, and 2 days interval using the equations of prediction of parturition date were 64.3%, 22.8% and 12.8%, respectively. The overall accuracy of prediction table of parturition day based on the ICCD and HD was 100% accurate within 2 days. Therefore, the prediction table seems to be a useful tool of the prediction of parturition day in practice.

Serial ultrasonographic examinations were daily performed from 15 days after ovulation until parturition to determine the growth curve of gestational structures in pregnant Maltese, Yorkshire terrier, Shih-tzu, and Miniature Schnauzer bitches, respectively. 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. The inner chorionic cavity diameter were significantly and linearly relative to gestational age especially days 20 to 40, and the fetal head diameter were significantly and linearly relative to gestational age especial1y day 40 to parturition. These results indicate that inner chorionic cavity diameter were the most accurate for estimating gestational age before day 38 of gestation and the fetal head diameter were after day 38 of gestation.

Serial ultrasonographic examinations were daily performed from 15 days after ovulation until parturition to determine the time of first detection and ultrasonographic appearance of the fetal and extra-fetal structures in pregnant 10 Maltese, 10 Yorkshire Terrier, 15 Shih-tzu, and 10 Miniature Schnauzer bitches, respectively. Gestational age was timed from the day of ovulation (day 0), which was estimated to occur when plasma progesterone concentration was first increased above 4.0ng/ml. The gestational length was (range: ) days and the geatational length was no statistically significant difference among bitches (p>0.05). The initial detection of the extra-fetal structures were; gestational sac at days , zonary placenta at days , yolk sac membrane at days , yolk sac tubular shape at days , and amniotic membrane at days , respectively. The time of the first detection of the extra-fetal structures were no statistically significant difference among bitches (p>0.05). The initial detection of the fetal structures were; embryo initial detection at days , heartbeat at days , embryo bipolar shape , fetal movement at days , limb buds at days , stomach at days , urinary bladder at days , skeleton at days , and kidney at days , respectively. The the time of the first detection of the fetal structures were no statistically significant difference among bitches (p>0.05). These results indicate the evaluation of the time of first detection and ultrasonographic characteristics of the gestational structures might be useful for pregnancy diagnosis, estimating fetal age, embryonic resorption, fetal monster, abnormal fetal growth and fetal viability, respectively.

애완견의 털에 부착되어 있는 세균을 분리 동정한 후, 이 분리 세균들에 대한 항세균효과가 있는 생약재 추출물을 탐색하였다. 애완견의 털에서 76개의 세균을 분리한 결과, Staphylococcus속이 41균주로 가장 많았으며 그 다음으로 Micrococcus속이 21균 주, Enterococcus속이 8균주, Bacillus속이 3균주, Exiguobacterium속 of 2균주, Shigella속과 Zoogloea속이 각각 1균주씩으로 동정되었다. 이러한 결과는 개의 털에 존재하는 세균들이 사람에게 감염을 일으킬 수 있는 원인이 될 수 있음을 시사한다. 분리균주들에 대한 항생제 저항성과 생약재 추출물의 항세균 활성은 디스크 확산법으로 확인하였다. 황금의 추출물이 애완견의 털로부터 분리한 세균들에 대해 높은 항세균 활성을 나타내어 항생제 저항성이 있는 세균들에 대한 새로운 항미생물제로 사용학 수 있을 것으로 기대된다.
