Zuko, the 2½-year-old French Bulldog, just became the face of every pet who’s ever been tricked into taking their meds. In a now-viral moment, his owner cleverly tucked a pill into a slice of banana and handed it over like nothing was up.

Zuko happily munched away, blissfully unaware… until a few seconds later, when his expression shifted from joy to betrayal. He coughed, paused, and then dramatically walked away, clearly realizing he’d been duped.

The pill was for Syringomyelia, a neurological condition caused by fluid buildup in the spinal cord that can lead to pain, weakness, and other symptoms. Despite the seriousness of the condition, Zuko’s reaction brought a moment of levity.

The owner tried to sneak the medicine into a banana, but the dog wasn’t fooled after one bite, it made its displeasure hilariously clear.
