I actually saw this on a tv show before! (We watch a lot of Animal Planet
) Anyway, the vet on the show just said to "stick it back in". I'm not a pro on this topic, so I'm not sure if this is the right advice and I wouldn't want to jeapordize your baby's health in any way. I'd just thought I would share that you are not the only one that this happened to, so good for you for asking! The vet said it was a male thing, and when it doesn't go back in, just aide the process. However, this is probably different case to case. If it keeps happening, I would maybe take him in. Good luck!!
