Deaf Therapy Dog Starts School-Tears Over What Students Do Next
A heartwarming clip showing elementary school students performing a song in American Sign Language to their deaf therapy dog has left internet users in tears.
Chris Hannah, 48, a music teacher at Dr. William Mennies Elementary School in Vineland, New Jersey, shared the TikTok footage of the students serenading Cole, @deafcole, a 9‑year‑old deaf pit bull mix who works as a therapy dog at the school. The clip has racked up more than 1.6 million views and over 267,000 likes on the platform.
In the video, a large group of students sing “Hero” by Mariah Carey, which they learned especially for Cole. The dog, unfazed and relaxed, lounges at the front of the room-seemingly more interested in a nap than the emotional moment unfolding around him.
Hannah told Newsweek: “About 200 students in grades 3-5 did a project in the music room about heroes. So many students wrote that Cole was their number one hero and wanted to dedicate the project to him.
“So we all brainstormed how we could communicate this to him, and the obvious answer was with American Sign Language.
“The students spent several class periods, learning piece by piece to learn the song with signing. The funny part is that they would only practice while he was napping, not to ruin the surprise for him. If he woke up while they were rehearsing, they would all immediately stop signing. It was a very heartwarming experience from the start.”
Hannah described cole as “very laid back, king of snuggles,” who “adores his job.” He has been part of the school community for years and plays multiple roles throughout the day. As a therapy dog, Hannah said, Cole is “the first thing the students see when they arrive on their buses,” often waiting outside to greet them each morning. He also spends his days in the music classroom, where Hannah teaches grades K through 5.
“He helps students-and even staff-who may be having a rough day, brings smiles in the hallways and on the playground,” Hannah said. “But his biggest role is being a special needs advocate. Cole is a role model for inclusion and showing students that what makes you different is what makes you beautiful.”
Cole's deafness, Hannah said, actually enhances his role as a therapy dog. “Loud noises and crowds never startle him,” the teacher added. “He may not be able to hear with his ears, but he listens with his heart and gives his undivided attention to those who need it.”
Hannah said that Cole's impact has been recognized well beyond the school walls. He was named American Humane Hero Therapy Dog in 2022 and went on to become the ASPCA National Dog of the Year in 2023.
Social Media Reacts
TikTok users were deeply moved by the moment-some emotional, others amused by Cole's calm reaction.
“I was not expecting to cry at 6:30 in the morning,” one viewer, Krystina Stephens, wrote.
“He don't give a damn I'm crying,” joked another user, Jon.
“This is how I feel when everyone is singing happy birthday,” added C.
Others noted the contrast between the students' dedication and Cole's laid‑back demeanor.
“Like my brain wants to tear up cuz this is so cute, but this dog absolutely could care less about what's going on, and I can't stop laughing,” Brittney Smith commented.
“Brb [be right back] while I cry meanwhile he just wants a snack and a nap,” another user wrote.
Several commenters praised the students themselves, with one writing that it was “the dedication of the students to actually learn the sign language” that made the video especially powerful.
