Imagine learning that your furry best friend has a rare medical disorder that will cause their bones to grow to epic proportions. That’s exactly what happened when Christopher Cline took his dog Juji to the vet to find out why he hadn’t stopped growing. Although the vet assured Chris that this rare disorder wouldn’t cause Juji pain, it would come with a unique set of challenges, including how to find a collar that fits and where to store all that dog food. Over three million people have viewed Chris and Juji’s story, but is it real? Is Juji really the world’s largest dog, or is this just an example of a gigantic lie?
