When a pint-sized Chihuahua named Niblett arrived at the Humane Educational Society (HES) just a few weeks ago, staff immediately fell in love. Weighing barely over 2 pounds, the cheerful puppy was impossibly small — but it didn’t take long for caregivers to realize there was something more going on.
Along with his big personality, Niblett was facing a serious medical challenge.
After further testing, veterinarians confirmed their concerns: Niblett had hydrocephalus, also known as “water on the brain.” The condition prevented part of his skull from fully fusing, leaving a soft spot that made even the smallest bump potentially life-threatening.
“[I]t soon became evident that Niblett had a serious medical condition,” HES wrote in a press release shared with The Dodo. “The condition made him extremely vulnerable to minor injuries, posing a significant threat to his life.”
Determined to protect the fragile pup, shelter staff began brainstorming solutions — no easy task given Niblett’s tiny size. Then Officer Leigh Stacy had a simple but brilliant idea.
“Niblett needs a cap.”
Veterinarian Dr. Samantha Blair agreed, and soon an unexpected partnership formed. She reached out to the University of Tennessee at Chattanooga’s College of Engineering and Computer Science, where associate professor Dr. Trevor Elliot and recent graduate Connor Mackey immediately volunteered to help.
“As soon as I saw Niblett’s cute little face, I said, ‘We’ve got to help,’” Dr. Elliot said.
With Mackey’s experience in 3D printing, the team got to work — starting with an exact scan of Niblett’s head. Working alongside Volkswagen’s Justin Stephens, they created a detailed 3D model of the puppy’s skull.
From there, the team designed several versions of protective headgear, testing and refining each one until they landed on the perfect solution.
“Ultimately, they created a football helmet-like design that Niblett quickly took to,” HES wrote.
When Niblett finally tried on his custom-made helmet, it fit him perfectly. Even better? He didn’t seem to mind wearing it at all.
Since then, he’s been sporting his tiny helmet daily — and caregivers have already noticed a positive difference.
“We believe he’s in the best possible place to have a good outcome and the longest life he can in a happy home,” said Sarah Callahan, HES’ director of veterinary services.
While Niblett is still waiting to find his forever family, he’s surrounded by love and care at HES. His caregivers are more than happy to protect him, cheer him on, and watch him thrive — helmet and all.
“As Niblett continues his journey, he stands as a testament to the extraordinary lengths people will go to save a life,” HES wrote. “It’s really cool that you can save a dog’s life using these techniques.”
