SUMMARY
Heart and body weights were obtained from 230 Greyhounds during necropsy. Sex and age were recorded for each Greyhound. Twenty-nine racing and 21 nonracing Greyhounds among the 230 dogs were compared. Heart-to-body weight ratio was calculated. Statistical analysis was done to determine the effects of age, sex, and racing on heart and body weights and heart-to-body weight ratio.
In adult Greyhounds, mean ± SD body weight was 28.4 ± 3.1 and 31.5 ± 2.8 kg, heart weight was 355.6 ± 52.8 and 381.4 ± 50.8 g, and heart-to-body weight ratio was 1.3 ± 0.2 and 1.2 ± 0.2% for females and males, respectively. Heart and body weights were significantly different between sex and age groups and among nonracing and racing males. However, heart-to-body weight ratio was not significantly different among age, sex, or racing groups.
