ABSTRACT
Safety pharmacology studies in dogs often integrate behavioral assessments made using video recording with physiologicmeasurements collected by telemetry. However, whether merely wearing the telemetry vest affects canine behavior and otherparameters has not been evaluated. This pilot study assessed the effect of a telemetry vest on behavioral and physiologic responses to an environmental stressor, the sounds of a thunderstorm, in Labrador retrievers. Dogs were assigned to one of 2 experimental groups (Vest and No-Vest, n = 8 dogs per group) by using a matched pairs design, with a previously determined,sound-associated anxiety score as the blocking variable. Dogs were individually retested with the same standardized soundstimulus (thunderstorm) in an open-field arena, and their behavioral responses were video recorded. Video analysis of locomotor activity and anxiety-related behavior and manual determination of heart rate and body temperature were performed;results were compared between groups. Vest wearing did not affect total locomotor activity or rectal body temperature butsignificantly decreased heart rate by 8% and overall mean anxiety score by 34% during open-field test sessions. Our results suggest that the use of telemetry vests in dogs influences the measurement of physiologic parameters and behaviors that areassessed in safety pharmacology studies.
