The normal BP values vary reflecting differences in subject populations, measurement techniques, and animal handling. However, accurate measurement of BP depends on several factors. Cuff height is one of the factors. This study was to evaluate the relation between BP variation and vertical distance from the heart base to the cuff less than 10 cm. BP of 47 anesthetized dogs were measured by oscillometric method when the cuff was placed at the level of shoulder joint (at the level of aortic valves), 0-5 cm, 5-10 cm, and >10 cm below the shoulder joint. The cuff height could affect the BP values when the cuff is 5-10 cm below the shoulder joint. In the normal BP group, the linear regression showed that with a 1.0 cm descend in cuff height can expect a 0.5 mm Hg rise in systolic arterial pressure. Nevertheless, the result maybe be masked by the anaesthetic. A clinical evaluation of BP in dogs was also performed in this study. The oscillometric procedure was used to measure the BP of 174 dogs that were brought to National Chung Hsing University of Veterinary Medical Teaching Hospital (100 in the group with heart disease [HD], 7 in the group with kidney disease [KD], and 67 in the control group). In the investigation of the BP in all the groups, there were no significant differences in HD, KD and control group. No correlations were identified between gender and body weight with BP. It was noted that the dogs of the control group that were less than 9 kg had a small increase in BP of 1 mm Hg/year. In the HD group, medications that were given for treatment had no influence in BP. It is important to address the cuff should be elevated to the level of the shoulder joint to 0-5 cm below when BP is measured. Despite this study only reveals a significant correlation between age and BP, the individual difference should be noted when interpreting BP measurements obtained from dogs.
