Introduction

Adult dog

The domestic dog (Canis lupus familiaris) has been derived from an ancestoral wolf and now consists of a breed family of more than 300 worldwide, with extensive variations in morphology (size, shape and weight). The modern dog breeds show high phenotypic diversity and are thought to have arisen from this first population bottleneck associated with wolf domestication (7,000–50,000 generations ago) and a second from more recent intensive selection to create the breed (50–100 generations ago).[1]

The average canine gestation period from ovulation to birth (parturition) is approximately 64 days and there have been identified about 400 congenital disorders relating to dog development.

Many of these developmental abnormalities are common to human development. The list below links to information on the Online Mendelian Inheritance in Animals.
