Abstract

Establishing methods and actions to improve performance and reduce changes during physical activity is essential in search and rescue dogs. Studying the changes in search and rescue dogs during working activities and how to correct them can help improve their performance and avoid complications. Six healthy adult dogs, which had participated in search and rescue operations for at least one year, were used. Animals had no evidence of clinical disease nor received any supplement or medication prior to the assessment. Dogs were evaluated before, during, and after exercise and submitted to volume replacement with mineral water (T1) and hydroelectrolytic supplementation (T2). Body temperature (BT), parameters of hydration (body weight, erythrogram, and total protein (TP)), energy indicators (glucose, lactate), electrolytes (K+, Na+, Cl-, P+, Ca2+, Mg2+), and hormone levels (cortisol, aldosterone, insulin) were determined. After exercise, isotonic dehydration was detected in both treatments, accompanied by erythrocytosis and weight loss. During the recovery phase, in both treatments, dogs presented a significant increase in BT and lactate and a significant decrease in insulin, TP, and P+. BT and lactate increased after exercise and returned to basal upon recovery. Insulin decreased after exercise without changes in glucose. The maintenance of cortisol indicated the adjustability of dogs to environmental stimuli and stress resistance, and aldosterone did not change during exercise. Both volume replacement with water or hydroelectrolytic and energetic supplementation can correct the isotonic dehydration exhibited by dogs.
