[Dynamics of the white blood cell picture during prolonged stress of training in the dog].

Thirty clinically healthy dogs of two age categories were studied for the effect of long-continued training load upon the pattern of the components of the white blood picture of dogs. There is a number of changes--leucocytosis, elevation of the neutrophil granulocytes, depression of lymphocytes and eosinophil granulocytes. These changes vary with the age of the dogs. They can be considered as manifestations of myogenic reaction under physical load and under stress, and as manifestations of a gradual adaptation in the course of training. The results can be included in the set of tests within the scientific system of dog training.
