An eleven year old, male, collie presented for evaluation of a right facial mass. The mass was located rostroventrally to the right eye. Antibiotic therapy was initiated. The mass did not regress and two weeks later it was reevaluated. A small amount of pus was obtained from the mass by needle aspiration. The teeth were cleaned at this time and more antibiotics were dispensed.
