On 4 December 2016, Mandowal Call for Tonyawire (Cleo) participated in the CACIB Belgrade International Dog Show in Serbia.

At this exhibition, Cleo was awarded Best Junior, completing the requirements for the title of Serbian Junior Champion.

With this result, she became Romanian, Hungarian, and Serbian Junior Champion, reflecting the consistency of her results during her junior show career.

Participation in international exhibitions allowed Cleo to be evaluated under different judges and in competition with quality Scottish Terriers from several countries. These early show results formed an important part of her development before becoming the foundation female of the Tonyawire Kennel Scottish Terrier breeding program.
