War of the stray dog
The events began on October 22, when a Greek soldier ran after his dog, who lost his way across the border from Greece, so it was sometimes called the "stray dog war." Bulgarian border guards shot the Greek soldier. According to the Greek army, a Greek captain was also killed.
In view of the tense political climate, the situation escalated, and in response, the Greek dictatorship led by General Theodorus Bangalos sent a military force to Bulgaria, in an attempt to occupy Petrich. It also sent a letter to the Bulgarian side demanding:
Punish the leaders of the Bulgarian force responsible for shooting against the Greek soldiers. An official apology from the Bulgarian government for the accident. Compensation of six million Greek dirhams for the families of the victims.
Bulgaria was given 48 hours to accept the Greek demands.
