All pieces are accounted for. And, since I’ve paid for an obstruction before, I am aware of the cost. Also the signs. Knowing what the odd behavior means is a plus because I can confidently say he needs an x-ray, even if I don’t know what is missing.I would worry that a horses head may cause the dog bowel obstruction.
That would not be cheap to fix - and we know you don't need another "plumbing" problem......
