Bruno the Boxer’s Tears Have a Medical Explanation, and a Whole Lot of Heart

A boxer named Bruno has gone viral for a reason most pet owners have never seen—he appears to “cry” when begging for treats. But as his owner revealed, those tears are more than just an emotional plea.

Bruno, a six-year-old boxer dog, has been by Hannah Fouts’ side since he was five months old. The two have been inseparable ever since, moving together from Pennsylvania to North Carolina and sharing every milestone in between. But what makes Bruno stand out isn’t just his loyalty—it’s his deeply expressive eyes, which literally fill with tears when he wants food.

In a now-viral TikTok video posted to @bruntheboxer, Bruno is seen standing beside a man eating a banana. As the man takes a bite, Bruno gazes longingly at the treat. Soon, tears begin to roll down his cheeks. The caption reads, “How are we supposed to say no when he literally cries,” and viewers agreed—racking up more than 11.5 million views and over 2.3 million likes.

What initially seemed like an exaggerated case of puppy eyes turned out to be a medical condition. Bruno has Keratoconjunctivitis sicca (KCS), also known as dry eye, a disorder where a dog’s tear production is significantly reduced. After exhausting medication options, Fouts agreed to a specialized surgery where part of Bruno’s saliva gland was rerouted to provide natural moisture to his eyes.

The surgery was successful, but with a unique twist: now, whenever Bruno smells food, his saliva glands activate, and tears stream from his eyes. In his case, this reaction is so strong it can temporarily impair his vision. “He’s run into walls and walked into pools,” Fouts said. “But after he settles, his vision comes back.”

Some viewers expressed concern in the video’s comments, wondering if Bruno’s tears were a sign of pain. But Fouts reassured followers that it’s simply a side effect of the surgery—one that, in Bruno’s case, has made him a little internet-famous. As she put it, “He took puppy eyes to a whole other level.”

Whether he’s begging for bananas or bumping into a coffee table, Bruno has captured hearts around the world—and shown that even medical quirks can become something beautiful.
