Three dogs accidentally ingesting superball, radiolucent elastic ball, were successfully treated by gastrotomy and intensive cares. All dogs ingesting the superballs had shown severe vomiting, and two of them were in dangerous condition by severe dehydration and electrolyte imbalance at admission. Furthermore, the dog of case 1 showed mild renal insufficiency and unconsciousness. Radiography revealed severe gastric dilation in the dog of case 2 that suggested complete obstruction of the pylorus by the ingested superball.
Foreign bodies were not conclusively diagnosed by plain radiography, however, their presence was demonstrated on positive contrast films. The superballs were located at the pyloric portion of the stomach in 2 cases (cases 1 and 2), and at the corpus of the stomach in a case (case 3) . These findings suggests that the superball accidentally ingested by the dog may have the risk to obstruct the pylorus and cause severe dehydration and electrolyte imbalance seen in these cases. After the intensive cares mainly with intravenous electrolyte solution therapy, the gastric foreign bodies were removed by gastrotomy. The general condition of the affected dogs recovered soon after the operation.

Subluxation of the fetlock joint with medially displaced phalanges of the forelimb was radiographically diagnosed in 3 dairy cows. The cause of subluxation of case 1 was unknown, however, the periosteal new bone formation at the affected joint may suggest that a certain period had past after the luxation. Other two cows (cases 2 and 3) were considered to be luxated when their limbs were caught in chains which tied the cow to the stall.
Under the sedation with xylazine, subluxated joint was reduced by the traction of the affected limb and the hand. In case 1, the dislocation could not be reduced. In case 2, the procedure was attemted on the third day of onset of subluxation and the dislocation was successfully reduced. In case 3, complete reduction could not be performed on the ninth day of luxation. After the reduction, affected joint was fixed with plaster. The prognosis of case 2 was quite good and, in case 3, the lameness disappeared 2 months after the reduction.
