The body condition score（BCS）is a subjective and semi-quantitative assessment of the nutritional status of dogs. The method, though popularly used, is not always accurate, and scores can vary among observers. In the present study, we examined if an objective morphometric analysis could be used to estimate BCS in dogs. Three anatomically defined body lengths were measured in 42 dogs of 19 different breeds, size and sexes and analyzed for correlation with ideal body weight（IBW）, which was estimated by current body weight and body fat percentage. As a result, a high correlation was found between IBW and the length between the episternum and the ischial tuberosity. Using the regression expression, theoretical IBWs were calculated. BCS was estimated based on the difference between IBW and current body weight. These results suggest that a simple morphometric measurement can be a practical alternative to the conventional BCS assessment.
The body condition score（BCS）system is used by veterinary practitioners worldwide for the assessment of the nutritional status of small animals. The BCS is a subjective method performed by visual observation and palpation, and results can vary among observers. For this reason, we developed a canine BCS palpation model and reported its effectiveness in minimizing the inter-observer variability. In the present study, a questionnaire-based survey was conducted to evaluate the usefulness of the improved version of the model among veterinarians and dog owners. The majority of the veterinarians perceived that the palpation feeling of the BCS model was in good agreement with actual patients. We also found that although most veterinarians were routinely performing BCS assessment and communicating the results to owners, however,most dog owners did not know about BCS. Thus, the BCS model is likely useful as a communication tool between veterinarians and owners during nutritional consultation. This is especially important given the high prevalence of obesity among pet dogs.
Measurements of glucose concentration by urinalysis test papers are generally accepted for kidney diseases and diabetes mellitus（DM）examinations in veterinary medicine, but the actual urine glucose concentration values have remained undetermined. Here, by using a digital meter（UG-120-H; Tanita,Tokyo）, we identified the urine glucose concentrations in 233 dogs and 124 cats. In the physiological conditions, the sugar concentrations of the dogs' urine（36±17 mg/dL）were significantly higher than those of the cats（32±12 mg/dL）, and the excretion of glucose into urine increased with an age-dependent manner in both the dogs and cats. Our findings suggest that this digital device enables the identification of the existence of 30 - 40 mg/dL glucose in the urine of healthy dogs and cats.
