ABSTRACT Some morphological traits of Ven dogs
This study was carried o u t to determine some morphological traits of Ven dogs A total of 36 dogs v/ere raised from birth to 12 m o n t h s of age to record some morphological indicators such as live vi'eight, lengths of muzzle, tail and the limbs, body height, and circumferences of chest and waist.
The results showed an increasing trend of weight and other dimensions m Ven dogs from birth to 12 months. The weight of newborn dogs at birth, 1, 6 a n d 12 months old was 265.7, 864.9, 8,411.4, and 13,327.8g, respectively. From 6 m o n t h s to 12 m o n t h s of age, there was a non-significant growth observed on the lengths of tail, front a n d hind limbs a n d body height. Male dogs showed higher values in most of the dimensions compared to those of female dogs However, the differences were not significant (P>0.05). At ali obsevation times, live weight and body measurements of male and female mare dogs were correlated, b u t the older the dog's age, the less the correlation coefficients were found. The results of this report may be useful for further studies on the Ven dogs, as a basic potential genehc for the breeding selection and domestication of this breed in Vietnam.
Keywords, Ven dog, body weight, body height, chest circumference, waist circumference
