Comparative Analysis of Hematological Parameters in Working Police Dogs

Hematological parameters were analyzed in working police dogs.The analysis of hematological parameters included three dog breeds: Belgian Shepherd dogs-Malinois (n = 27), Labrador Retriever (n = 54) and German Shepherd (n = 55), fifteen months to 10 years old.Training excercises affects their hematological parameters distinctly when comparing different dog breeds.Statistical analysis showed significant values for packed cell volume values (p = 0.01), hemoglobin concentration (p = 0.00) and reticulocytes (p = 0.01) between compared breeds.In group from 2 to 7 years statistically significant differencies were obtained for packed cell volume (p = 0.00), hemoglobin concentration (p = 0.00) and reticulocytes (p = 0.003).Similar hematological values between Malinois and Labrador Retriever were obtained, and it can be concluded that German Shepherd dog can conduct more intensive trainings than Malinois or Labrador Retriever dogs.The obtained results enables the establishment of hematological and biochemical reference values in these three dogs blood breeds that will support clinical diagnosis and further research into working police dog physiology.
