Footage reveals odd behavior
Over the next few days, they observed the footage. Bruno acted normally around most people, wagging his tail and appearing friendly.

However, when specific people walked in, his demeanor changed drastically. He’d whimper, bark, and pull away as though terrified.
Mary observed the odd behavior, perplexed. ‘What’s different about these people?’ she wondered aloud, scribbling down notes and marking the timestamps on the footage where Bruno acted out.
