No Angie, but I will throw my .02 worth in.
It didn't completely eliminate the threat with mine, but I would do it all over again in a heartbeat. I will always pexy any Chows I get in the future. I actually do think it saved my girl's life. They told me the twist was high up on the esophagus, not down in the stomach area. She had only twisted on one end, the other was holding. I think if it had twisted on both ends we wouldn't have been able to save her. So, which not the total cure-all I hoped it was, I do think it was totally worth it.
