[The leukocyte status of surviving dogs as compared to dogs dying from parvovirus infections].

The white blood picture was examined in 135 dogs with parvovirus disease during the course of the illness. 91 dogs survived, 44 died. The surviving dogs showed higher mean total leucocyte, neutrophil, and eosinophil counts whereas the mean lymphocyte, neutrophil, and monocyte counts on the first day of the disease were lower in those dogs which survived than in those ones which died later. Increasing lymphocyte and monocyte counts appear to be a favourable prognostic sign. The older the dogs, which fell ill, were, the more favourable the prognosis turned out.
