[The effects of the stress of long-term physical and psychological training on the red blood cell picture in dogs].

The effect of the physical and psychical load of long-continued training on the components of the red blood picture was studied in thirty clinically healthy dogs of two age categories. The values of erythrocytes were found to be increased whereas those of haemoglobin, haematocrit and other components (MCV, MCH, BI, MCHC) were depressed. The effects are discussed of training, adaptation process, parasympathicotonic form of overload, and qualitative nutrition deficiency as a reflection of the studied training load as exerted on certain insufficiency of the desired formation of the red blood picture, and thereby of a possible adverse impact on the performance of the trained dog.
