The dog was first treated with palliative care by putting pressure bandage. But it did not respond and subcutaneous emphysema extended to shoulder and whole body including limbs and tail. Subcutaneous gas was partially expelled through three stab incisions on back. Shaving of hair at the suspected ventral part of cranial neck revealed bite marks in skin and hence the case was suspected to have perforation in trachea. Later surgical exploration under general anaesthesia confirmed perforation of trachea and was corrected. The clinical symptoms subsided and the animal showed uneventful recovery.
