Summary The purpose of this study is to report the aterial blood gas findings in dogs with bacterial pneumonia. Arterial blood gas samples were collected from 62 dogs with culture-confirmed bacterial pneumonia. These results were compared with 46 normal dog arterial blood gas samples. Results demonstrated that respiratory acidosis was not a problem in dogs with pneumonia in this study. Significant evidence of hypoxemia was noted with abnormal mean values in PaO2 (P

Summary Apparent restihg energy expenditure (AREE) and respiratory quotient (RQ) were determined by open flow indirect calorimetry in a group of 104 apparently resting, critically ill, postoperative and severely traumatized dogs. The evaluations were conducted in a calm, temperature-controlled environment after at least a 12-hour fast. Subjects were allowed to acclimilate to the monitoring equipment prior to beginning the study. The clinical patients were compared to a group of 20 clinically normal, apparently resting, client owned dogs (NC). The data was also compared to published normals (NP) for energy expenditure of apparently resting dogs. Measurements were indexed to actual body weight in kilograms (BW) as well as to metabolic body size(BW0.75). Measurements of VO2 (VO2/kg and VO2/kg0.75) and VCO2 (VCO2/kg and VCO2/kg0.75) were used to calculate the RQ and the AREE. Critically ill, postperative and severely lower RQ values AREE/kg or AREE/kg0.75 (p=0.39). The PO&T dogs did exhibit significantly lower RQ values (p
