Abstract
The purpose of this paper is to describe some fundamental physiological data in F 1 hybrids bred from a Mexican hairless dog and beagle cross. These F 1 hybrids numbered 5 hairless dogs and 12 haired dogs. The hematological profile of these offspring was assessed via an automated cell counter and compared with those of healthy beagles. In hairless dogs, red blood cell count, hemoglobin concentration and packed cell volume tended to be higher than in beagles. White cell distribution curves in hairless dogs and beagles yielded a single peak, while in haired dogs one or two peaks were present. Red blood cell and platelet distribution curves revealed few differences among the 3 kinds of dogs.
