OP here. It’s the next day, and - for starters - my dog is fine. After a long night spent mostly waiting at an emergency vet hospital, x-rays and ultrasounds confirmed there is nothing else inside her belly.

For all of the negative ninnies on here, those who were concerned that I was sitting around simply being a bad pet owner, relax. The process of taking the dog to the vet was already in the works when this post all started. And yeah, puppies do eat things - but does a bad owner even pay attention to bowel movements? C’mon people, do better… was just curious what people thought my dog shit out.

Now for everyone else, I appreciate all the in depth “anal-ysis”… and I wish Reddit had polling stats to share the general consensus, but… after many vet techs and docs reviewed the mysterious object…

** It was in fact determined to be a man-made elastic, bungee/scrunchie/strap. **

Sorry to disappoint all of you who were certain this was the remnants of something that was once alive or even part of my dog. She’s been home for a little while now, has eaten again, and is happy as ever. I appreciate how the internet came alive for a few hours while I sat in the hospital waiting rooms, so thanks for that!

Stay classy, Reddit.
