A dachshund in England stunned his owner and vet when he blew up to three times his normal size after air from his windpipe became forced under his skin. As a result the dog took on a balloon-like appearance, but luckily was “deflated” by his vet, and is now reported to be doing well.

Four-year-old Trevor was rushed to the emergency vet after he mysteriously bloated and experienced trouble breathing, The BBC reported. The pooch was soon diagnosed with sub-cutaneous emphysema, a rare condition where air collects under the skin. The air had escaped from a hole in Trevor's windpipe. The dog was soon admitted to surgery where vets stitched up the hole in his windpipe and relieved the pressure of the air buildup under his skin.

"I have never seen a case like this before and it was a new surgery for me,” the performing veterinarian Michelle Coward of the Beech House Surgery in Warrington and the Willows Veterinary Group, told the BBC. "Every time he took a breath, some of the inhaled air escaped through a hole in his windpipe."

It's not clear how the hole in the windpipe occurred, as there were no visible external wounds. His owner, Fran Jennings, from Lymm, Cheshire in England was equally confused about the root of Trevor's mysterious ailment and explained that the dog's appearance seemed to change suddenly.

“We came down one day and found Trevor in a bad state, he literally looked like he'd blown up like a balloon and we had no idea what had happened,” Jennings told the Manchester Evening News.

Sub-cutaneous emphysema is not restricted to our canine friends and can also occur in humans. These pockets of air are often the result of either blunt or penetrating trauma, and may also occur as a result of infection of surgical complications. However, they may also be spontaneous. While these pockets of air are often minimal, they can sometimes be severe or even life-threatening in humans. The pockets can put pressure on the airway and interfere with the lungs' abilities to fully re-expand. In Trevor's case, the air under his skin was also affecting his heart, The BBC reported.

Trevor's emergency surgery was able to address his problem, and a bit of manual deflation helped the pooch shrink back to his normal size. His owners report that he is also back to his normal playful self and hopefully, unaware of the mysterious yet serious health issue he was able to escape.
