What does the rainbow bridge mean? Do people actually think that our pets die and are jettisoned to some magical bridge with a rainbow constantly hovering over it? Is it a bridge formed out of a rainbow? Then what happens? So.... they're dead, go to the rainbow bridge and then what? They are like, in heaven, living in eternal bliss..... is that what you all mean. Does it have something to do with the song "somewhere over the rainbow! I am sincerely curious, otherwise I would not inquire. Please correct me if I am mistaken. Sounds like a very interesting take, that's for sure. I have never had a clue as to what the hell this means. Merely guesses.
