I wanted to find out about a narration. I have heard that it has been narrated in Ahadith that in the time of the holy Prophetﷺ, a woman made an vow that if such a thing happens, then she will sit and eat with dogs. After this incident, she became Muslim, and the condition for fulfilling her vow came true…. (until the end of the narration)
After thoroughly searching through the authentic books of Ahadith, we were not able to find any such narration similar to that as mentioned in the question. However, one must not practice upon statements that has been merely heard of, nor should he ascribe them to the holy Prophetﷺ without having proper knowledge of their authenticity. This must be avoided.
And Allah knows best.
