I hope it turns out to be nothing! Let us know. Prayers for him that he's fine. Cracker ate a pincusion once when he was 9 months old, the kids had left it down and he thought it was a ball. He swallowed several pins. He was able to pass them all though, after being fed cotton balls, and the vets didn't find anything on x-rays. I'm sure Buck will be okay, it's not your fault, if he did get something it was an accident.
