In this paper, we would like to clarify the progressing of healing processes of stomach, morphological and histological development of the stomach after using the autogenous vascularized jejunum flap to reconstruct the experimental gastric defect in 10 stray dogs of both sexes. A protocol of anesthesia include atropine sulphate as a premedication followed by Xylazine /Ketamine at the dose of  3, 10 mg /kg B.wt respectively were used successfully in the present trial Clinicopathological and histopathological examination were performed to justify the current hypothesis. The results of the present trial include no characteristic clinical signs except signs of anorexia and vomiting for the first few days which subside after good hygiene and proper management. Grossly the implanted graft difficulty was distinguished from the gastric tissue. There is a circular ulcerative lesion just at the site of operation in one of the operated animals 2 months post-operatively. Histologically, the complete healing occurs at sixty days post-operatively with mature fibrous tissue, collagen fibers and available number of fibroblast cell. In conclusion, the utilization of the pedicle and taper jejunum flap to replace the damaged stomach is considered as an alternative reconstruction procedure. It is an acceptable method after partial gastrectomy in dog.
