We once had a dog that ate a bunch of tinsel off the Christmas tree. We found this out when lengths of tinsel started coming out of his ass. Vet did x-rays, a sizeable bill was issued, and we were told that we had to wait until the dog shit out all the tinsel and were not allowed to pull it out in any way once the extruding tinsel was visible on his rear end because of a concern that this could damage or cut his intestines. For several weeks my wife and I drew straws to determine who was going to carefully trim the tinsel sticking out of the dogs ass.
