Canine parvovirus (CPV) is one of the most important cause of mortality in young dogs and no specific treatment exists. Since prolonged leukopenia greatly increases the risk of death in infected pups, strategies to counteract this decline were investigated. The outcomes of CPV naturally infected pups treated with the recombinant canine granulocyte-colony stimulating factor (rcG-CSF), in combination with the routine therapy, were compared with similarly-managed infected pups not treated with rcG-CSF. A non-randomized prospective clinical trial was performed on 62 CPV infected pups with WBC counts <3000 cells/μL and two different groups were selected based on a non-randomized approach. Group A dogs (31/62) received 5 μg/Kg of rcG-CSF daily from the hospitalization day until WBC reached the reference range (3–5 days) and group B (31/62) received 1 ml of placebo injection. All dogs in group A recovered, while five dogs in group B died. The rcG-CSF treatment demonstrated a statistically significant effect on WBC counts (p < 0.0001) and, surprisingly, also on lymphocytes and monocytes counts (p < 0.0001). There was no significant effect of treatment on neutrophil count (p = 0.5502). Although lymphocytes and monocytes are not a specific target for rcG-CSF, our study highlights that rcG-CSF is able to improve haematological parameters compared to untreated dogs and a clear increase in their number was detected, as previously described for humans treated with the homologous molecule.
