Since uploading the footage, the TikTok video has become a viral hit and watched over 49.9 million times and gained 7.6 million likes.
One TikTok user said: “I love this dog, he makes me smile with each step.”
Another jokingly commented: “I think your dog was a horse in his past life.”
In another video posted on Fenix’s page, his owners revealed that their pet almost had his end before it began, where he was dropped off at a kill shelter.
Fenix was left abandoned alongside his sister Nube, who also suffers from the same condition, where they were both unable to stand up.
