Hematologic Values in Mongrel and Greyhound Dogs Being Screened for Research Use

SUMMARY Hematologic and blood chemistry data were collected from Greyhounds and from mongrel dogs. Data were distributed according to sex and, in the case of the mongrels, according to weight. The Greyhounds' mean values for red blood cell (rbc) counts, for packed cell volume (pcv), and hemoglobin (Hb.) determinations were greater than those of the mongrels, in most cases significantly so (P < 0.01). The mongrel dogs, on the other hand, had higher mean values than the Greyhounds in reference to the white blood cell (wbc) counts and the relative percentage of eosinophils. The serum sodium, chlorides, bilirubin, and glutamic oxaloacetic transaminase values were greater, and in most cases significantly so, for the Greyhounds in comparison to the mongrels. The mongrel dogs had a higher total serum protein and a lower serum albumin content than did the Greyhounds. The female Greyhounds had a significantly higher blood urea nitrogen value than did the mongrels. The mean alkaline phosphatase activity values were significantly higher for male mongrels weighing less than 15 kg. than for male Greyhounds.
