Changes in Pulse Rate, Respiratory Rate and Rectal Temperature in Working Dogs before and after Three Different Field...

Physiological changes (pulse rate, respiratory rate and rectal temperature) induced by exercise are usually studied as physical fitness indices. The aim of this study was to investigate how these physiological parameters could be modified in a group of trained working dogs during three different field trials (rubble, search on field, obedience), in order to assess which parameter would be more useful to detect the dog response to exercise. Nine dogs were included in this study. The animals were monitored at rest, immediately before and after the working session. Pulse rate values increased significantly in all the phases compared to rest status. Respiratory rate values increased significantly after the competition, while rectal temperature was significantly increased only after search on rubbles and obedience activities. Reference values for specific competitions need to be stablished in order to promptly identify poor performance or exercise intolerance.
