Yeeps, that's scary! I only have a dog that tries to catch flying bugs, and she went after a bee. We couldn't tell if she had really had contact with it or not (she was wiping at her face), and kept her in the room with us to make sure her muzzle didn't inflate like it had when she was a puppy.
I met a lady who was sure her 12 year old son woke up every day and said to himself; "what can I do to kill myself today?" She couldn't remember how many times she'd been to the ER!
