Hematologic values of captive Mexican wolves.

Hematologic reference values were determined for a captive population of 11 Mexican wolves (Canis lupus baileyi). Wolf pups from 4 to 24 weeks old had progressive age-related increases in PCV, hemoglobin concentration, mean cell volume, and RBC counts similar to those seen in domestic dog pups (C familiaris). Hematologic indices in wolves older than 24 weeks were comparable to those of the adult domestic dog; however, PCV, hemoglobin concentration, and RBC counts were higher.
