A particularly sharp and well-trained K9 officer named Rex had been the pride of the force, often visiting schools to educate and interact with children. But during one of these routine visits, his incessant barking at a particular teacher raised concerns among the staff.

Initially, the teachers and students thought Rex’s barking was just a playful act, a sign of excitement. However, when the barking continued and grew more intense every time the dog was near this specific teacher, the officer handling Rex decided to investigate further.
