Analysis of hematological and biochemical variables in searchand rescue dogs

Abstract

Exercise can induce a series of physiological and laboratory changes depending on some factors such as type of exercise, intensity, frequency, and level of training of the dog. This study aimed to evaluate changes in blood count, leukogram, and biochemical parameters before and after each search performed by the animals. Samples were collected before starting the first search (T0), right after the first search (T1), after the lunch break before starting the second search (T2) and right after the second search (T3). The study was based on verifying changes between these intervals, to also assess possible muscle injuries resulting from efforts made during exercise, with the hypothesis of changes in the blood count due to splenic contraction and gas exchange, we sought to verify changes. Six dogs were studied, four of the Bloodhound breed, a male Belgian Shepherd and a female Labrador Retriever that were submitted to search work. Clinical signs of exhaustion or exercise intolerance were not observed in the dogs during the study. In the course of the studies, no alterations were identified that deviate from the normal physiological pattern.
