Injuries in dogs, which are the result of fights, vary greatly in location and in severity. The following is a case in which the right zygomatic arch was fractured and a hernia produced in a fight with another dog. The patient in this case was a 5-year-old Black and Tan Terrier male which was brought to the Stange Memorial Clinic on March 3, 1944. The owner stated that the dog had been in fights with other dogs, and that he had acquired an enlargement on the abdominal wall, which had become lacerated in one of the fights. Also, there was a deep wound posterior and ventral to the right eye.
