Description
Summary:•After field search and rescue exercises, changes in serum chemistry and blood gases are similar to other endurance activities.•The lack of hemoconcentration suggests that in extreme heat and humidity, dogs with access to water do not undergo dehydration.•The exercise did not produce oxidative stress, and metabolic processes were adequate to protect the dogs.•This study provides important reference data for the evaluation of search and rescue dogs during and after field work. The aim of the study was to assess the physiological and antioxidant status before and after a 4 h search and rescue field exercise, with handlers, under warm-weather conditions performing activities compared to a control group of similarly trained dogs at rest. Serum chemistry demonstrated a decrease in serum sodium (Na) and potassium (K) in both exercising and control groups, however only Na was decreased significantly (P
