Abstract

Demand for dog is on an increase because they are used as watchdog, hunting and its breeding serves as a source of income to both rural and urban dwellers. As demand is increases, breeders often mate dogs at premature age thereby causing several complications from conception to birth.

This study was aimed at considering the post-natal development of the uterus from histomorphological aspects and to correlate features to attainment of puberty. Hysterectomy was carried out to secure the uterus from Day 2, Week 4, Week 8, Week 12 and Week 20. This developmental study attempted highlighting some silent microanatomical parameters, including the circular muscle, longitudinal muscle, myometrial glands, blood vessels and epithelial features of the uterus in the Nigerian indigenous bitch. The inner circular muscle and the germinal epithelium were the first microstructures to be observed on day 2 and week 4 of postnatal development respectively. Within these range of development, little or no histological variations occurred. Simple columnar epithelium and longitudinal smooth muscle were seen on the twelfth week. The inner circular muscle and outer longitudinal muscles made up the fundamental component of the smooth muscle. The significant of this study is to indicate histological changes that takes place within the uterus and this finding show some corresponding relationship that exist between age and uterine development, an indicator for determining puberty.
