Zuni is 1 year old Yorkie/Boston mix. She has vomited the same almost identical substance 5 or 6 times now, not frequently, usually a month or so apart. The substance feels very rubbery and is semi flexible and has no real odor. I have scoured the areas of the house she has access to and cannot find anything even remotely close. It also looks nothing like anything we have fed her, and no part of any of her toys matches it. Here are a couple of pics of the latest one from a few days ago:

This morning, I noticed a similar one in her poop, not as large, a lot smaller and thinner, but definitely the same type of material.

Does anyone have any idea what this could be?
