Introduction: To assess the health and fitness status of dogs and to control the effects of physical activity
caused by physical work hematological, biochemical and metabolic data are of great interest in
veterinary medicine. A variety of changes in blood parameters can occur in dogs in response to
the physical work, but these are only sparsely documented in dogs.
Question: The aim of this thesis is to provide an overview of existing literature to demonstration the
different blood parameters that are used in performance diagnostics in the dog.
Materials and methods: With the help of the search engines PubMed, Scopus, ISI Web of Knowledge, Medline, Scirus
and the catalog of the University library a total of forty studies that deal with the issue of
performance diagnostics in the dog could be found.
Results: Based on the analysis of the included studies, the hypothesis that these parameters show
significant changes after performance and thus be meaningful, can only be confirmed for certain
parameters and certain forms of exercise. The following parameters showed clear results during
sprint races: lactate (significantly increased), hematocrit (significantly increased), hemoglobin
(significantly increased), total protein (significantly elevated), glucose (significantly increased),
pH (significantly reduced), oxygen partial pressure (significantly increased), partial pressure Carbon dioxide (significantly decreased), bicarbonate (significantly decreased). Also the retrieval
which is very similar to the performance intensity of the sprint races provided significant values:
lactate (significantly increased), creatine kinase (significantly increased), pH (significantly
increased), partial pressure of carbon dioxide (significantly decreased).
Conclusion: The examined blood parameters of the studies and the different forms of exercise (submaximal,
maximal work) sometimes differ considerably and had different results. Clear results were found
particularly in the wake of sprint race. This may be explained by the fact that these races are
standardized and that these dogs have an identical training status and a similar training program.
The results in this thesis can possibly serve as a basis for further studies.
