A lot of surgery is done to remove objects that they can block the bowel if too big to pass. Some dogs repeatedly. Always a risk with any surgery.
As a puppy, our Timmy swallowed a few macadamia nuts that fell from trees. The shells are smooth and really hard.
I have had bandicoots digging under many of my plants, but especially bearded iris. They don't appear to eat anything unless it is some roots. But something did chomp down some fans. maybe hares, although they usually prefer the daylilies.
