The phrase "went to the rainbow" is often used as a euphemism for death, particularly in reference to pets like dogs. This expression has its roots in the idea of a rainbow bridge that connects heaven and earth. According to this myth, when a pet dies, it goes to a beautiful meadow where they can run and play with other pets until their owner joins them. At that point, they all cross the rainbow bridge together into heaven. This notion provides comfort to many pet owners by suggesting that their beloved companions are not gone forever but rather waiting for them in a better place. It also helps children understand death in a less frightening way. The use of "went to the rainbow" is a gentle and poetic way to express that a dog has passed away, acknowledging both the sadness of the loss and the hope for reunification.
