At Spooner Veterinary Clinic, A lab puppy presented with vomiting and a hard lump in the abdomen. No brainer on the foreign body, but what it was, was very surprising.
The puppy had chewed the tip off a tip up ice fishing rod, and just kept on going, eventually swallowing the whole thing, almost 18" long. Amazingly, he was able to retrieve the whole rod pulling it out through the mouth. Puppy went home this morning just fine..
