This study was prepared to compare between the skin of local and wild rabbits. The samples were taken from five body region (ear, abdomen, neck, thorax and back ).The present study revealed that the basic structure of the skin in local and wild rabbits formed of supperfacial layer is epidermis, which covered with keratinized stratified squamous epithelium and arranged into four rows from cells, beside thickness of epidermis in local rabbit more than that thickness of epidermis in wild rabbits .The deep layer is dermis which dermis divided into two layers, the superficial papillary and deep reticular layers without a clear line demarcation between two layers. Local rabbit dermis was thicker than that wild rabbit dermis due to density of dense irregular connective tissue and fibers. There are two types of hair follicles in both animals was primary and secondary hair follicles. The follicles consists of one into three primary hair follicles and clusters of secondary hair follicles in local rabbit whereas in the wild rabbits, the follicles consists of central primary hair follicles and several of smaller secondary follicles surrounded the central primary hair follicles.
