INTESTINAL OBSTRUCTION IN THE DOG: ITS BY CECIL FRENCH, D V.S., THE WASHINGTON (D. C.) CANINE INFIRMARY. THE term "intestinal obstruction" includes all cases in which the onflow of the contents of the intestinal canal is obstructed. The less degrees of constipation do not, however, form part of the consideration. Occlusion of the canal is sometimes congenital, most frequently in the region of the anus (atresia ani), where the integument remains imperforate or the rectum ends in a blind. sac. The classification of all other cases into three principal groups, adopted by the late George Ross, M.D., in an article on "Intestinal Obstruction in the Human Being," is equally applicable to the dog: I. From compression, obliteration of the canal taking place from pressure without. II: From obstruction, blocking of the canal by obstruction within its walls. III. From constriction, obstruction by causes developing in connection with the wall itself. 1. Obstruction arising from compression without may be due to slits in the mesentery or omentum.
